- FIG. 3 is a diagram illustrating a putting green 300 having various turf analysis locations along with turf analysis data according to an embodiment of the subject matter disclosed herein. Such a view may be displayed on a display at any computer such that a user may utilize and interact with data collected and to be collected by a turf analysis device 100 .
- a putting green 300 is shown; however, any depiction of turf may be rendered such as a fairway, sports field, or even a simple block diagram showing regions of turf to be analyzed.
- the putting green shows four turf analysis locations. There may be many more in a typical analysis, but four are illustrated here for the purposes of this embodiment. The four locations correspond to references A 310 , B, 320 , C, 330 , and D 340 .
- the locations may correspond to actual locations in which the turf analysis device 100 was used to determine specific factors (e.g., data collected) about the turf. These factors may be assimilated into a turf analysis algorithm (discussed below) to determine an overall turf quality indicator known as turf performance indicator (TPI). These turf performance indicators may be displayed in a table 350 .
- TPI turf performance indicator
- Turf performance in and of itself, may be the result of several factors.
- the factors may be determined using a turf analysis device 100 within a turf and soil insight system.
- the collection of data about the various factors makes it possible to effectively measure key variables that indicate turf performance and turf stress to be assessed for current and/or trending conditions.
- lab analytics can be used to indicate key characteristics that become very powerful indicators when combined with in situ measurements of key variables of the turf.
- several variables sometimes called stresses
- an algebraic equation may be used to assess the performance of a turf system against any one turf variable/stress.
- TPI Turf Stress Index
- the formulas are written to allow the optimum levels to be customized while taking into account tolerance factors for each variable.
- the data collected may be assimilated into an analysis application to keep track of real time measurements using one or more stationary sensor systems. Further, the application may assimilate data collected from measured variable or ratio of variables captured from portable monitoring, in-ground monitoring, lab analysis, or observational measurements that are made scientifically and practically.
- the individual TSI calculation can be applied to any number of variables that can be recorded from the turf analysis device 100 , a turf analysis weather station, other soil sensors, lab analysis reports, and any other variable where a comparison of the actual versus the optimum can be made.
- the formula takes into account several factors that influence turfgrass performance.
- the various stresses that can be measured include soil moisture, soil salinity (sometimes called electrical conductivity (EC), ambient temperature, canopy temperature, and EC/moisture ratio.
- TTI Turf Stress Indicator
- TSI Turf Stress Indicator where 100 is the least likelihood for the particular stress; zero is the highest likelihood.
- the TPI may be thought of as the turf's strength against a particular stress. So a score of 100% means the turf is likely not under any pressure from that stress, or variable.
- e mathematical constant of 2.71828 which is approximately the base of the natural logarithm.
- x measured variable of interest (moisture, salinity, temperature, (EC/moisture ratio, and the like).
- xo optimum value for the variable of interest (user′ definable and determined from a large network of users and collected data, customizable per customer's tolerances and key property or zone attributes determined from observations or lab analysis).
- TOL a defined tolerance factor for each measureable variable essentially defining the delta around an optimum value (i.e., if optimum salinity is 0.21 dS/m and it is desired to allow a range of 0.15 to 0.27, TOL would be 0.12). Again, this is customizable and unique.
- the formula will look like that below and will not only calculate the TSI but will indicate whether the value is below (indicated by a negative value) or above the optimum level. This is important for several variables. For instance, if moisture has a 70% stress performance score, it may be important to know if it is too moist (positive value) or too dry (negative value) causing this less than optimum condition.
- B 3 is a column assignment for measured condition
- a 3 is the column assignment for the optimum condition
- C 3 is the column assignment for the TOL factor
- a reference to the actual measured value minus the optimum value is made before combining the +/ ⁇ symbol to the calculated TSI Value.
- B 3 is the column assignment for the measured condition
- a 3 is the column assignment for the optimum condition
- EC moisture stress with limited salinity
- Another turf performance condition exists. If there are elevated moisture and salinity stresses, then an entirely different turfgrass performance level exists. This can be the case for any number of variables.
- the three most easily ascertained, and which are three of the most influential variables on turf performance include moisture, salinity (EC), and temperature. Further, with regard to temperature in particular, turf canopy, or surface temperature is a direct measurement of temperature's influence on turf stress.
- the turf analysis device 100 directly measures these variables using research grade multi-parameter sensors requiring no calibration in any turf/soil type. This makes the repeated capturing of these variables easy and applicable to apply these calculations to understand how well the turf system is performing at any given time.
- the consistent measurements of research grade multi-parameter sensors results in a universally comparable TPI value using different turf analysis devices and across many geographically locations. For example, a golf course in one geographical region can compare the TPI to another golf course in a separate geographical region.
- turf performance can be suffering from external influences not directly measurable.
- pathogenic fungi can be invading a particular turf plot and causing disease decline even when temperature, moisture and salinity measurements are not indicating there is a problem.
- Pathogenic fungi are influenced by increased heat and moisture, but the attack on turf plants is not necessarily increased due to this.
- the recovery of the turf is directly related to the turf's performance at the time of disease onset. Therefore, having knowledge of turf performance indicators or having a quantitative value to associate with a qualitative condition has application in disease likelihood assessment or any other ailment that can result in turf decline.
- using a customized visual analysis of the conditions may allow the input of a number indicating such visual appearance into the turf performance indicator calculation allowing for a measurement of the overall turf performance to include a visual inspection.
- TPI is high (>85%)
- turf performance is generally acceptable and least likely to develop conditions leading to declined performance.
- a weighted average Turf Performance Indicator can be calculated.
- Using a weighted average formula where this formula above would be calculated for any number of variables (e.g., salinity, moisture, temperature, ambient temp/humidity, traffic, and the like) and each of those variables are assigned a weighted value from 1 to 5 for instance, a summation of the result of multiplying each individual TSI by the weighted value and then dividing that total by the sum of all of the weighted values is calculated.
- TPI total weighted average TPI on the same 0 to 100 scale indicating the overall TPI of the turf (or crop, land stress, runoff potential, etc.). While the weighted average values are being assessed with much data being collected over the past years and moving forward, the initial formula treats each variable equally. However, here is the weighted average formula written out:
- Turf Performance IndexWAvg ⁇ (100/[( e 0.5( x ⁇ x 0/ TOL )2]) TSI 1 +(100/[( e 0.5( x ⁇ x 0/ TOL )2]) TSI 2 +(100/[( e 0.5( x ⁇ x 0/ TOL )2]) TSI 3 +TSI n calculations ⁇ /(Weighted valueTSI1+Weighted valueTSI2+Weighted valueTSI3+Weighted value TSI n )
- TPI ⁇ 100/[( e 0.5( x ⁇ xo/TOL )2]) TSI 1+100/[( e 0.5( x ⁇ xo/TOL )2]) TSI 2 +100/[( e 0.5( x ⁇ xo/TOL )2]) TSI 3 +100/[( e 0.5( x ⁇ xo/TOL )2]) TSI n ⁇
- a TPI report is used to summarize a report card for multiple TSIs as they relate to turf performance while giving insight to individual ‘scores’ that will direct attention to any one variable.
- the resulting TPI factor of the above combines the results of several variables into a quantitative analysis of the overall performance potential of a system called the Turf Performance Indicator. This calculation is implemented utilizing a database such as the turf analysis system 200 , and then the resulting determinations are relayed in near real time through the turf analysis application and cloud-based computing system.
- the turf analysis device 100 itself is unique so this calculation is truly unique and based upon the value of much recorded data from turf systems around the globe.
- Another TSI to be considered includes measuring the effects of temperature and moisture together.
- stresses set in that are influenced by that temperature.
- moisture has a particular impact on turf performance as well.
- both temperature and moisture rise above their optimum levels the combination of the two have a much more negative influence on turf performance.
- a calculation measuring the points away from optimum for both variables combines these results to get a total departure from the two together and indicating the stress that this combination causes.
- an optimum temperature level is 78 degrees F. and the turf is at 88 degrees in the canopy (measured by the turf analysis device 100 ), a 10-point variance from optimum is recorded.
- the optimum moisture value is 0.25 wfv, or 25% wfv, and a turf value at 0.38, or 38% wfv, then there is a 13-point variance from optimum for moisture. The combined effects of these would be 23 points from optimum. This is one way to measure the effects of the two variables together. More complex forms of this calculation are possible as more and more data is collected from the turf analysis system from turf systems around the world.
- Lab Analytics may be used in turfgrass and agronomy applications for understanding soil influences or water, tissue, pathogenic fungi, and microbiological influences as well.
- One particular way to use lab analytics here is to develop a turf analysis Soil Health Report. In this report, some specific information is ascertained to understand what the optimal levels are for the particular soil being tested. Each turf analysis ‘zone’ that is identified at a particular property will have different specific conditions only identified by this analysis.
- the variables that are recorded may be used in a logarithmic assessment and have applied optimum levels based on user-determined algorithms. These optimum levels drive how far away from optimum the condition is.
- a Saturation Percentage may be determined indicating how much water an equal part of soil takes to saturate, or reach field capacity.
- an ideal condition for a particular soil and for a quality turfgrass surface may be achieved when the user can maintain a moisture percentage (wfv) that is 40% of the saturation percentage.
- the measurement may be further refined to include a bulk density of the sample that indicates whether a dense layer exists in the turf system or not. Soil tests may not identify the existence of such a layer despite the fact that these layers are very detrimental to turf systems and have a significant impact on water holding and salinity holding capacities of the turf system as whole. This analysis overcomes these issues. Additional report guidelines are contemplated.

- a user of a turf analysis device 100 may begin collecting field data by identifying and selecting specific turf locations to analyze at 410 . Once a turf location is selected, the turf analysis device may be inserted in the turf and activated at 412 .

Abstract
Description
- The present application claims priority and benefit from the U.S. Provisional Patent Application No. 62/298,886, filed Feb. 23, 2016 and titled, “SYSTEM AND METHOD FOR DETERMINING TURF QUALITY INDICATOR”. The entire content of the provisional application is herein expressly incorporated by reference. Further, the present application refers a commonly-assigned U.S. patent application Ser. No. ______, entitled “SYSTEM AND METHOD FOR TRACKING AND OPTIMIZING PINHOLE LOCATIONS ON A PUTTING GREEN” filed on ______, and commonly-assigned U.S. patent application Ser. No. ______, entitled “SYSTEM AND METHOD FOR INSTANTANEOUSLY DETERMINING UNIFORM DISTRIBUTION OF WATER, SALINITY, CONDUCTIVITY, TEMPERATURE AND OTHER CONDITIONS IN SOIL” filed on ______, the disclosures of which are incorporated by reference.
- Golf is a sport enjoyed by millions of people the world over. Its popularity indicates that interest in golf remains vibrant and growing. As a result, groundskeepers (which include golf course greenkeepers and superintendents) are always seeking to enhance the playing experience for golfers while increasing efficiencies in maintaining turf including fairways, putting greens and other areas of the golf course property in additions to sports fields, parks, and other land covered in grass turf. Many variables may affect turf quality including moisture content, water retention and drainage, soil contents and conditions, salinity influences, weather, and use patterns. Thus, groundskeeper are continuously monitoring various conditions in an effort to maintain or improve the quality of the turf.
- One particular area in which groundskeepers are keenly aware of involves overall turf quality both on putting greens and in fairways. Many factors may be used to determine overall turf quality. These factors include relative hardness, moisture content, resilience, temperature, conductivity, salinity, and the like. However, in addition to years of education, groundskeepers typically hone their craft through years of trial and error experience such that a feel for the turf may be developed. Of course, the “feel” may differ from course to course and from groundskeeper to groundskeeper. Conventional golf course maintenance does not have any objective, standard, or measurable indicators. Turf performance indicators (TPI) may be used to determine the overall performance quality of the turfgrass system.
- Aspects and many of the attendant advantages of the claims will become more readily appreciated as the same become better understood by reference to the following detailed description, when taken in conjunction with the accompanying drawings, wherein:

FIG. 3 is a diagram illustrating a putting green 300 having various turf analysis locations along with turf analysis data according to an embodiment of the subject matter disclosed herein. Such a view may be displayed on a display at any computer such that a user may utilize and interact with data collected and to be collected by aturf analysis device 100. In this illustration, a puttinggreen 300 is shown; however, any depiction of turf may be rendered such as a fairway, sports field, or even a simple block diagram showing regions of turf to be analyzed. Further, the putting green shows four turf analysis locations. There may be many more in a typical analysis, but four are illustrated here for the purposes of this embodiment. The four locations correspond to references A 310, B, 320, C, 330, andD 340. The locations may correspond to actual locations in which theturf analysis device 100 was used to determine specific factors (e.g., data collected) about the turf. These factors may be assimilated into a turf analysis algorithm (discussed below) to determine an overall turf quality indicator known as turf performance indicator (TPI). These turf performance indicators may be displayed in a table 350. - Turf performance, in and of itself, may be the result of several factors. The factors may be determined using a
turf analysis device 100 within a turf and soil insight system. The collection of data about the various factors makes it possible to effectively measure key variables that indicate turf performance and turf stress to be assessed for current and/or trending conditions. In addition, lab analytics can be used to indicate key characteristics that become very powerful indicators when combined with in situ measurements of key variables of the turf. In an effort to assess the turf performance quality of any turf grass system, several variables (sometimes called stresses) may be individually measured and then used to tailor lab analytics to include key assessments associated with understanding what monitored measurements mean as far as their insight to true turf conditions. In one embodiment, an algebraic equation may be used to assess the performance of a turf system against any one turf variable/stress. Such an equation yields a Turf Stress Index (TSI) that is associated with the specific variable being measured. Further, using a weighted formula, one may combine the effects of several stresses to indicate a Turf Performance Indicator (TPI) score, which is an indication of turfgrass performance as a whole. That is, several TSIs may be combined to generate an overall TPI. - The formulas are written to allow the optimum levels to be customized while taking into account tolerance factors for each variable. The data collected may be assimilated into an analysis application to keep track of real time measurements using one or more stationary sensor systems. Further, the application may assimilate data collected from measured variable or ratio of variables captured from portable monitoring, in-ground monitoring, lab analysis, or observational measurements that are made scientifically and practically.
- The individual TSI calculation can be applied to any number of variables that can be recorded from the
turf analysis device 100, a turf analysis weather station, other soil sensors, lab analysis reports, and any other variable where a comparison of the actual versus the optimum can be made. The formula takes into account several factors that influence turfgrass performance. The various stresses that can be measured include soil moisture, soil salinity (sometimes called electrical conductivity (EC), ambient temperature, canopy temperature, and EC/moisture ratio. - The Turf Stress Indicator (TSI) calculation for a single variable is
-
TSI=100/[(e0.5(x−xo/TOL)2]Var1 - In this formula, the variables are: TSI=Turf Stress Indicator where 100 is the least likelihood for the particular stress; zero is the highest likelihood. The TPI may be thought of as the turf's strength against a particular stress. So a score of 100% means the turf is likely not under any pressure from that stress, or variable.
- Another variable is e=mathematical constant of 2.71828 which is approximately the base of the natural logarithm. Another variable is x=measured variable of interest (moisture, salinity, temperature, (EC/moisture ratio, and the like). Another variable is xo=optimum value for the variable of interest (user′ definable and determined from a large network of users and collected data, customizable per customer's tolerances and key property or zone attributes determined from observations or lab analysis). Another variable is TOL=a defined tolerance factor for each measureable variable essentially defining the delta around an optimum value (i.e., if optimum salinity is 0.21 dS/m and it is desired to allow a range of 0.15 to 0.27, TOL would be 0.12). Again, this is customizable and unique.
- In a spreadsheet, the formula will look like that below and will not only calculate the TSI but will indicate whether the value is below (indicated by a negative value) or above the optimum level. This is important for several variables. For instance, if moisture has a 70% stress performance score, it may be important to know if it is too moist (positive value) or too dry (negative value) causing this less than optimum condition.
-
TSI (Spreadsheet Language): =(100/2.71828̂(0.5*((B3−A3)/C3)A2)) - Where:
- B3 is a column assignment for measured condition
- A3 is the column assignment for the optimum condition
- C3 is the column assignment for the TOL factor
- To determine whether the value is to the positive or negative size of optimum, a reference to the actual measured value minus the optimum value is made before combining the +/− symbol to the calculated TSI Value.
-
Positive or Negative (+/−) value determination (Spreadsheet Language): =IF(B3−A3<0,“−”,“+”) - Where:
- B3 is the column assignment for the measured condition
- A3 is the column assignment for the optimum condition
- Note that ‘+’ is assigned to 0 values and above and ‘−’ values are assigned to <0 values.
- Turf Performance Indicator (Moisture, Salinity (EC), Temperature)
- To calculate the performance of a turf system, several factors may be considered. For instance, if there is a moisture stress with limited salinity (EC) stress, then one level of turf performance exists. If there is the same turf system with low moisture stress but increased salinity stress, then another turf performance condition exists. If there are elevated moisture and salinity stresses, then an entirely different turfgrass performance level exists. This can be the case for any number of variables. The three most easily ascertained, and which are three of the most influential variables on turf performance, include moisture, salinity (EC), and temperature. Further, with regard to temperature in particular, turf canopy, or surface temperature is a direct measurement of temperature's influence on turf stress. The
turf analysis device 100 directly measures these variables using research grade multi-parameter sensors requiring no calibration in any turf/soil type. This makes the repeated capturing of these variables easy and applicable to apply these calculations to understand how well the turf system is performing at any given time. The consistent measurements of research grade multi-parameter sensors results in a universally comparable TPI value using different turf analysis devices and across many geographically locations. For example, a golf course in one geographical region can compare the TPI to another golf course in a separate geographical region. - However, even when measured variable conditions are optimal, turf performance can be suffering from external influences not directly measurable. For example, pathogenic fungi can be invading a particular turf plot and causing disease decline even when temperature, moisture and salinity measurements are not indicating there is a problem. Pathogenic fungi are influenced by increased heat and moisture, but the attack on turf plants is not necessarily increased due to this. The recovery of the turf, however, is directly related to the turf's performance at the time of disease onset. Therefore, having knowledge of turf performance indicators or having a quantitative value to associate with a qualitative condition has application in disease likelihood assessment or any other ailment that can result in turf decline.
- Despite this fact that problems can still occur even when conditions seem optimal for good turf performance, using a customized visual analysis of the conditions may allow the input of a number indicating such visual appearance into the turf performance indicator calculation allowing for a measurement of the overall turf performance to include a visual inspection. Generally speaking, when the TPI is high (>85%), turf performance is generally acceptable and least likely to develop conditions leading to declined performance.
- By combining several Turf Stress Indicator results with weights to their influences applied, a weighted average Turf Performance Indicator can be calculated. Using a weighted average formula where this formula above would be calculated for any number of variables (e.g., salinity, moisture, temperature, ambient temp/humidity, traffic, and the like) and each of those variables are assigned a weighted value from 1 to 5 for instance, a summation of the result of multiplying each individual TSI by the weighted value and then dividing that total by the sum of all of the weighted values is calculated. There is now a total weighted average TPI on the same 0 to 100 scale indicating the overall TPI of the turf (or crop, land stress, runoff potential, etc.). While the weighted average values are being assessed with much data being collected over the past years and moving forward, the initial formula treats each variable equally. However, here is the weighted average formula written out:
-
Turf Performance IndexWAvg={(100/[(e0.5(x−x0/TOL)2])TSI 1+(100/[(e0.5(x−x0/TOL)2])TSI 2+(100/[(e0.5(x−x0/TOL)2])TSI 3+TSI n calculations}/(Weighted valueTSI1+Weighted valueTSI2+Weighted valueTSI3+Weighted value TSI n) - In a first phase, all variables are given equal weight, where n is the number of individual TSI's calculated, the Turf Performance Indicator without weighted averages applied would be:
-
TPI={100/[(e0.5(x−xo/TOL)2])TSI1+100/[(e0.5(x−xo/TOL)2])TSI 2+100/[(e0.5(x−xo/TOL)2])TSI 3+100/[(e0.5(x−xo/TOL)2])TSI n} - The more TSI values inputted to the calculation, the more representative the calculation will be to include as many influencing variables as possible. A TPI report is used to summarize a report card for multiple TSIs as they relate to turf performance while giving insight to individual ‘scores’ that will direct attention to any one variable.
- The resulting TPI factor of the above combines the results of several variables into a quantitative analysis of the overall performance potential of a system called the Turf Performance Indicator. This calculation is implemented utilizing a database such as the
turf analysis system 200, and then the resulting determinations are relayed in near real time through the turf analysis application and cloud-based computing system. Theturf analysis device 100 itself is unique so this calculation is truly unique and based upon the value of much recorded data from turf systems around the globe. - From a practical perspective, users can input respective tolerances and simply view the TPI at any given time to know where their system is from zone to zone, property to property (in the case of management companies and multi-facility operations), or from period to period. At no time does a user have to dive into this calculation. The proprietary nature of the calculation is done in the background while the user may adjust the optimum level and log conditions.
- The effects of EC and moisture together have multiple effects that influence turfgrass performance. It is not always enough to simply look at the moisture and salinity levels without understanding the relationship of these to each other. A ratio of EC to moisture, for instance, indicates the concentration of salts to a given amount of water. This is insightful to understand salinity issues besides just having elevated salts in the turf system. A calculation to understand this involves dividing the EC by moisture. Both would have to be in decimal format with moisture being reported as a decimal percentage water fraction volume (i.e., 0.22=22% moisture by water fraction volume (wfv)). Salinity (EC) on the other hand would be reported to two decimal places as well but reporting in deciSiemens per meter (dS/m) such as 0.65 dS/m. In this case, our EC/Moisture ratio would be 0.65/0.22=2.95. This is a unique way of determining the concentration of EC to moisture. This example calculation shows a very high EC/Moisture ratio indicating a high salinity concentration for a fairly low amount of moisture. Ideally in turf, the ratio should be around 1.00. However, with the increased demand to use reclaimed and effluent water sources on turf in particular, salinity levels are at an all-time high. This ratio must be considered in a turf system to truly understand turf performance levels at any given time.
- Another TSI to be considered includes measuring the effects of temperature and moisture together. In particular, as canopy temperature rises above an optimum level, stresses set in that are influenced by that temperature. As moisture climbs above an optimum level, moisture has a particular impact on turf performance as well. However, when both temperature and moisture rise above their optimum levels, the combination of the two have a much more negative influence on turf performance. To effectively measure this initially, a calculation measuring the points away from optimum for both variables combines these results to get a total departure from the two together and indicating the stress that this combination causes.
- For example, if an optimum temperature level is 78 degrees F. and the turf is at 88 degrees in the canopy (measured by the turf analysis device 100), a 10-point variance from optimum is recorded. In addition, if the optimum moisture value is 0.25 wfv, or 25% wfv, and a turf value at 0.38, or 38% wfv, then there is a 13-point variance from optimum for moisture. The combined effects of these would be 23 points from optimum. This is one way to measure the effects of the two variables together. More complex forms of this calculation are possible as more and more data is collected from the turf analysis system from turf systems around the world.
- Lab Analytics may be used in turfgrass and agronomy applications for understanding soil influences or water, tissue, pathogenic fungi, and microbiological influences as well. One particular way to use lab analytics here is to develop a turf analysis Soil Health Report. In this report, some specific information is ascertained to understand what the optimal levels are for the particular soil being tested. Each turf analysis ‘zone’ that is identified at a particular property will have different specific conditions only identified by this analysis.
- The variables that are recorded may be used in a logarithmic assessment and have applied optimum levels based on user-determined algorithms. These optimum levels drive how far away from optimum the condition is. In addition to this, a Saturation Percentage may be determined indicating how much water an equal part of soil takes to saturate, or reach field capacity. In one embodiment, an ideal condition for a particular soil and for a quality turfgrass surface may be achieved when the user can maintain a moisture percentage (wfv) that is 40% of the saturation percentage. The measurement may be further refined to include a bulk density of the sample that indicates whether a dense layer exists in the turf system or not. Soil tests may not identify the existence of such a layer despite the fact that these layers are very detrimental to turf systems and have a significant impact on water holding and salinity holding capacities of the turf system as whole. This analysis overcomes these issues. Additional report guidelines are contemplated.

FIG. 4 is a flow chart of a method for determining and using turf performance quality indicators for turf under analysis according to an embodiment of the subject matter discussed herein. The method may start at 400. A user of aturf analysis device 100 may begin collecting field data by identifying and selecting specific turf locations to analyze at 410. Once a turf location is selected, the turf analysis device may be inserted in the turf and activated at 412. At 414, the turf analysis device collects and determines one or more data points about the underlying turf at 412. At 414, the turf analysis device may store the data locally or upload the data to a nearby portable computing device that may be executing a turf analysis application. At 416, the local mobile device may display the collected data measures with theturf analysis device 100 and present the average of soil measurements within the specific turf location to provide an immediate visual turf performance conditions. At 418, a determination is made as to whether additional turf locations are to be analyzed. If yes, the method loops back to 410. If no, the user may proceed to 420. - At 420, the locally collected data may be uploaded to a server computer for further analysis and assimilation. Once uploaded, the data may be used in a series of algorithms at
step 422 to determine specific indicators about overall turf quality as discussed above. The indicators may then be used to determine an overall turf quality at 424. Additionally, lab analysis of turf samples may be used to determine additional indicators about the turf atstep 426. Then all indicators determined from direct lab analytics or algorithmic indicators may be assimilated in a set of overall results at 428. Based on the overall results, specific actions may be recommended or taken atstep 430. - Additional steps may be implemented that utilize additional information such as turf analysis or may discount some data because of anomalies.
