Description
TITLE: VARIABLE ZONE CROP-SPECIFIC INPUTS PRESCRIPTION METHOD
AND SYSTEMS THEREFOR
FIELD OF THE INVENTION
This invention relates to methods for managing agricultural crop production in large fields. More particularly, the invention relates to methods and systems for prescribing options for variable fertility and pest management inputs for optimizing crop production in selected agricultural fields.
BACKGROUND OF THE INVENTION
Increasing demands for increased efficiencies in crop production have resulted in the development of new agricultural production management tools, methods, and systems. Adoption of these tools has enabled significant improvements in crop yields harvested on a per-acre basis.
However, the efforts required for maximizing crop yields are difficult, time consuming, and costly because the characteristics of farmlands vary from acre to acre. This variance is due to a variety of factors including among others physico-chemical factors such as soil topography, soil nutrient availability, and environmental factors related to weather conditions particularly precipitation and temperature. Agricultural farmland productivity is also affected by the types of crops produced, their fertility requirements and their optimal environmental growing requirements. A constant challenge in all crop production management strategies is timely pest detection and control.
Current agronomic production strategies are focused on intensive fertilization to achieve maximized crop yields on individual fields. Such strategies require understanding of various physico-chemical characteristics of individual fields that could significantly affect crop yields.
Agricultural lands are typically comprised of several different soil types, each of which may be categorized according to differences in soil texture, soil profile characteristics, soil chemistry, and organic matter content. Some fields contain one dominant soil type that covers the majority of the field area with the remaining area made up of other different soil types. These other soil type areas are distributed around the field in various locations and have irregularly shaped boundaries, which often, but not necessarily, correspond to low or high spots.

Often, a field
-2-contains a plurality of irregularly distributed interfacing soil types.
Although any given plot of land or field may include many different soil types, its potential productivity and related fertilization requirements are additionally affected by post-production-cycle residual nutrient levels remaining in the soil matrix profiles throughout and about the fields.
Residual soil nutrient levels can vary considerably within a single field. For example, residual nitrate nitrogen levels can vary from about 0 to 200 lbs/acre or higher. According, it would be unusual if a field did not include at least two substantially different soils having substantially different fertilization requirements. Present methods generally determine nutrient requirements by taking soil samples from different areas of the field in a grid configuration in reference to yield data or multispectral satellite imagery. Characteristics such as soil composition and type comprising each soil sample are quantified and summarized. The depth and thickness of soil horizons and their properties can vary immensely within a landscape, and even within a given field. If a critical soil property, such as nutrient and water holding capacity or carbon content, is to be assessed within a given field or area, then it is critical that the vertical and horizontal distribution of such properties be determined accurately. When a soil core is collected, the number of sections analyzed in the sample limits the vertical resolution of the soil property assessment at that location. This is due primarily to the high cost and time expenditure associated with soil sample collection, preparation, analysis, and recording procedures. For example, if one producer managing farmland on the order of several thousand acres would require the collection and analyses of hundreds of soil samples from throughout their fields for the purpose of determining the pluralities of soil characteristics for which nutrient input requirements must be determined.
Extracting and analyzing this multitude of soil samples is cost prohibitive and does not provide a viable method for maximizing agricultural output. Typically, only a few locations across a landscape are chosen for core sampling, and only a few sample sections are removed from each core for analysis. This limited vertical soil information results in errors when attempting to model the spatial distribution and volume of soil properties across a landscape. Furthermore, the grid method may unintentionally allow a varied number of soil types and elevations to be included within a single area due to the irregularity in shape of the different areas of the field.
This is also problematic.
The type of the crop to be grown in a field will also significantly affect the fertilization requirements for maximal production of the crop. For example, protein and test weight for wheat

The type of the crop to be grown in a field will also significantly affect the fertilization requirements for maximal production of the crop. For example, protein and test weight for wheat
-3-can range 2.5 percent in a single 40-acre field. The yield can vary as well.
Typically, yields range from 50 percent less than the mean to 50 percent greater than the mean. Most applied nutrient amounts are determined by the expected yield of the crop. Therefore, it is important to determine yield potentials prior to application of fertilizers. Ideally, each of the individual areas of different soil should be treated independently for the purpose of applying seed, fertilizer, or other items to the field. Current practices are to prescribe items, such as seed and fertilizer, to the entire plot of land or section of the land, if using the grid method, according to the needs of the most deficient soil, or according to the averaged requirements of the different soils. Such practices commonly employ satellite imagery in combination with GIS software (i.e., geographic information system) or alternatively GPS software (i.e., global positioning system) for detecting and mapping selected fields, and for determining various attributes such as topography, estimations of soil moisture levels based on the brightness of the soil in high-resolution aerial satellite imagery, and estimations of a` normalized difference vegetable indeg'(i.e., NVDI) based on biomass extrapolations derived from multispectral satellite imagery. Such practices typically integrate the results of soil sample analyses with data derived and extrapolated from satellite images for preparation of soil fertility input recommendations that provide specific fertilizer input suggestions for each management zone within the field, based on field-averaging approaches for maximizing a crop yield.
Other problems encountered with the current agricultural production management tools, methods, and systems used for maximizing crop yields relate to recommendations prepared in reference to optimal growing conditions. Unexpected weather patterns occurring during the crop production cycle often reduce the beneficial effects of fertility inputs on subsequent crop growth and development. Crop plants are typically stressed significantly during extended periods of drought or alternatively excessive moisture, and during extended periods of unusually cold temperatures or alternatively high temperatures. Such stresses generally reduce plant metabolic rates and may have long-term debilitative effects of their physiological performance, thereby reducing the amounts of the applied fertilizers that are taken up by the plants. Consequently, in such stressed growing conditions, significant amounts of anionic macronutrient salts are leached away from the soil profiles while the cationic forms tend to accumulate in the upper soil horizons. Atypical weather conditions are commonly accompanied by pest infestations of the stressed crops that further reduce crop yields and add to the growers' production costs.

-9-An exemplary method and related system S for providing variable zone-based crop-specific fertilization prescriptions for a selected agricultural field is shown in Fig. 2. After a farmer selects an agricultural field 10 for which he wishes input prescriptions for selected crops to facilitate their crop selection and production management decisions, suitable high-resolution geo-referenced aerial imagery is obtained to determine and acquire the field's shape, dimensions, and boundaries. The fields boundaries can be saved as geo-referenced (e.g., GPS) shape file or polygon that is accessible by GIS-based programs. The fields topography can be integrated into one or more selected polygons from which a site-specific geo-referenced field shape file 20 is produced. It is optional to incorporate a site-specific topography map into the field shape file 20 if so desired. One of a site-related multispectral satellite imagery, and hyperspectral satellite imagery collected in previous years, is obtained and clipped onto the field shape file 20 to produce a site-specific vegetation sitemap 30. It is suitable if so desired to obtain, process and correlate several site related satellite imagery to produce an averaged satellite imagery to clip onto the field shape file 20. The near-infrared bands and red bands of multispectral imagery are vectored to a vectorized polygon grid, after which a normalized difference vegetation index (NDVI) pertaining to the distribution of ranges of biomass densities within and throughout the field, can be calculated 40. The NDVI values are then classified and grouped into several classes wherein each class has similar ranges of biomass density distribution. The classes are interpolated using suitable geostatistical techniques exemplified by kriging, nearest-neighbor, inverse distance, Delauney triangulation, minimum curvature, polynomial regression, radial basis function, Shepards method, the like, and combinations thereof, into about 4 to 8 zones that comprise the agricultural field. The NVDI classes may be created by methods of classification exemplified by natural breaks, equal area, equal intervals, the like, and combinations thereof.
The zones are then mapped onto one or more field map templates, and the number of acres within each zone is calculated 50. It is suitable to refer to these zones as`

-10-data using algorithms exemplified by fuzzy k-means clustering and by the minimum-volume embedding algorithm.
After the soil management zones have been delineated for the agricultural field, a pattern of soil sampling suitable numbers of sites within each soil management zone throughout the agricultural field is derived 60. Soil samples are then collected and analyzed for selected macronutrients and micronutrients, and at least some of soil pH, soil EC, soluble salts, texture, mineral composition and organic matter content 70. The soil analysis results provide a physico-chemical profile for each of the soil management zones. The physico-chemical profiles are then compared to reference data sets pertaining agronomic fertility inputs for optimal production of a selected crop, and the differences are then reported for each soil management zone 80. Using information provided by the farmer regarding the list of crops he is considering growing during the upcoming production season 100, agronomic recommendations for each of the selected crops e.g., 111, 112, 113, are input, and a set of equations 120 then calculates a set of fertilizer application rates (i.e., prescriptions) for selected macronutrients and micronutrients for each of the soil management zones for each of the selected crops 131, 132, 133.
Weather conditions and crop development occurring during a growing season often proceed outside of predictions and calculated projections that were made prior to crop sowing.
For example, unusually high ambient temperatures for extended periods of time coupled with ideal precipitation and soil moisture conditions can produce un-anticipated rapid rates of crop growth and development that may result in depletion of soil nutrient levels that were previously adjusted according to prescriptions. Alternatively, excessive precipitation coupled with unusually cool ambient temperatures could result in depletion of the anionic components of applied fertilizers through leaching (e.g., nitrates) or precipitation (e.g., phosphates) that may result in the occurrence of crop nutrient stresses. Accordingly, it is within the scope of the present invention to adapt the method and systems exemplified in Fig. 2 to provide one or more variable zone-based crop-specific inputs prescriptions during the course of a crop production cycle on a selected agricultural field, to augment crop inputs prescriptions provided prior to the commencement of growing season. It is known that different and varying concentrations of macronutrients and micronutrients in soils will cause changes in the reflectance of crops growing in those soils. Such changes in crop reflectance are detectable with hyperspectral imagery. In

Inputting data sets comprising hyperspectral information, in combination with other selected crop production parameter data, enables early detection of the potential occurrence and severity of macronutrient and/or micronutrient deficiencies associated with the unusual weather conditions occurring during the early stages of crop production.
Accordingly, the processing module then calculates using appropriately adapted algorithms, a set of in-season fertilization prescriptions for each of the soil management zones across the field to ameliorate the potential nutrient deficiencies thereby enabling mid-season optimization of crop production.
Several pest events invariably occur during the course of a crop production cycle.
Various types of pests exemplified by weeds, insects and microbial diseases are commonly associated with certain geographies, agronomic practices and/or crop types.
The severity of damage caused to the crop can be ameliorated by prophylactic applications of certain chemical pesticides, alternatively by early detection of pest appearance and immediate application of one or more suitable chemical or biological pesticides. Quite often, the severity of pest infestation is exacerbated by weather conditions. Accordingly, certain aspects of the present invention relate to use and analyses of data collected by several different pest monitoring and detection systems exemplified by crop scouting and satellite images, for early detection of localized pest appearance in one or more soil management zones comprising the agricultural field. An exemplary method and related system 200 for providing pest management prescriptions during a crop production cycle is shown in Fig. 3.

Historical weather data from previous production cycles 250 and current weather forecast projections 260 are input. Also input are suitable agronomic recommendations pertaining to recommended pest control products and management practices for each of the identified pests 270. The processing module 280 processes, calculates and correlates the pest scouting data sets with the NDVI zones across the agricultural field, the historical weather data, and with the current weather forecasts, after which the periods of highest risk for development of significant diseases, insect and weed pests are calculated, projected and reported. Concomitantly, the processing module 280 correlates the disease risk projections to reference data sets of chemical pesticides and biological pesticides and to the agronomic recommendations for pest management and provides prescription options ,e.g., 291, 292, 293, for selection of suitable pest control products, related recommended application rates for each of the soil management zones, and timing of applications.
Weed control products represent a significant cost for agricultural producers.
Current management strategies to control these costs are focused on booking volume quantities of selected herbicides in advance of the growing season in anticipation that certain weed pests will appear and will need to be controlled.

It is a common agricultural practice to rotate the type of crop grown on an agricultural field from year to year. Accordingly, providing the methods and systems of the present invention with a plurality of historical annual record inputs for an agricultural field whereon multiple crops have been produced over several production cycles, will enable averaging of historical production data for each crop.
