Definitions
- the present invention relates to devices and methods for determining an elemental composition in a soil, in particular in an agriculturally used, geogenically or anthropogenically designed soil.
- the invention is directed to a method for determining the element composition of the soil as a function of the depth and to a method for determining the element composition of the soil and to corresponding devices.
- the invention is directed to a method for treating an agriculturally used soil using a determined element composition of the soil.
- the object of the present invention is to at least partially overcome the problems known from the prior art and, in particular, to provide methods and devices with which the quality of a soil can be determined particularly efficiently and reliably across the board.
- a method for determining an element composition of a soil as a function of the depth includes:
- a soil can be characterized automatically.
- the element composition of a soil in particular can be determined with the method described. This means the distribution of the chemical elements in the soil.
- the element composition can also be referred to as the distribution of the element concentrations.
- the chemical bond state of the elements is not important.
- the composition of the elements is an important quality parameter in many applications.
- the determination of the element composition can also be referred to as a multi-element analysis.
- the method described is preferably applied to an agriculturally used soil, such as an agricultural area or a forestry area.
- the method described can also be used on soils influenced by anthropogenic influences, such as in a landfill.
- the described method can also be used in the context of geological exploratory drilling, for example for the development of deposits, for the development of groundwater or for the investigation of the ground.
- the raw material extraction potential of a soil can be determined, the solution potential of environmentally relevant substances in the groundwater development can be monitored or the potential use of a building site such as a former landfill can be determined.
- Possible contamination of the soil can also be assessed when dismantling industrial plants such as petrol stations.
- time delays caused by laboratory tests can be avoided. Any additional examinations that may be required can thus be carried out particularly easily because their necessity can be identified immediately.
- the quality of the soil in the form of the element composition can be determined particularly efficiently and reliably.
- Samples of the soil are taken and analyzed using LIBS.
- LIBS has the advantage that an analysis of the samples taken can be carried out on site, ie directly at the location where the sample was taken. The samples can therefore be analyzed particularly quickly.
- the element composition can be determined depending on the depth of the soil.
- depth is to be understood as a distance between the surface of the ground and a point under consideration within the ground. This can also be referred to colloquially as “depth”. For example, a depth of 1 m describes a point one meter below the ground surface.
- the core sample is preferably taken vertically. This means that one axis of the core sample is aligned vertically before the core sample is taken. It is also possible that the core sample is taken tilted against the vertical.
- the process can cover different depths.
- a maximum depth of 1 m can be sufficient because the roots of agriculturally used plants usually do not extend deeper into the ground.
- Considerably greater depths can be investigated in the case of anthropogenically influenced soils and, in particular, geological exploration boreholes.
- a depth-dependent determination of the element composition is possible with the method described in that the samples are taken in the form of core samples.
- a core sample is to be understood as a sample that is taken, for example, in the form of a drill core. If the method described is used on geological For exploratory drilling, a drill core obtained from a drilling represents a core sample.
- a core sample is a sample that is representative of a certain depth range of the soil.
- the depth-dependent elemental composition of the soil can thus be determined using the core sample.
- the core sample is preferably taken by means of a probe such as a ramming core probe, in particular by means of a so-called Pürckhauer.
- a ram core probe is a device with which a typically cylindrical core sample can be taken from the ground.
- the core sample preferably extends from the soil surface to a depth of 0.5 m, preferably even to a depth of 1 m. Such depth coverage is particularly well suited for many applications, especially in agriculture.
- the depth range over which the elemental composition of the soil can be determined by means of the method described.
- the method described has the advantage that it is not just an analysis of the surface of the soil.
- the core samples are preferably taken automatically. This means that a device for taking samples is used which automatically takes the core samples after switching on and setting. This can reduce the effort required to carry out the described method or, alternatively, enable a higher number of samples to be used with the same effort.
- the elemental composition of the soil is preferably determined as a function of the depth by direct analysis of the core sample taken using laser-induced breakdown spectroscopy, LIBS. "Directly" means that LIBS is applied directly to the core sample.
- the position of the removal is preferably determined, for example by GPS.
- the position can also be determined by means of the 5G cellular network.
- the core sample taken is analyzed using LIBS.
- the core sample is scanned along its length with a laser.
- the result is an element composition depending on the position along the core sample and, to that extent, depending on the depth of the soil.
- the core sample can be stored after it has been taken and then analyzed using LIBS. This has the advantage that the device used for the LIBS does not have to be subject to any special requirements, in particular in terms of size and shape.
- a fresh section of the core sample is preferably analyzed.
- the outermost 5 mm of the core sample in the radial direction can be peeled off by means of a burr. This can follow when pulling out and / or afterwards.
- the core sample can also be analyzed without peeling. This is particularly possible when smearing effects only occur to a small extent and / or when only a low level of accuracy with regard to the depth dependency is required.
- the core sample is analyzed during removal.
- a LIBS device is preferably used which is designed and arranged in such a way that the core sample is guided past the LIBS device when it is pulled out of the ground.
- the analysis be performed on a fresh gate. Analyzing the core sample while pulling it out has the advantage that the sample can be stored immediately after it has been taken without having to pay attention to the fact that individual parts of the core sample are displaced or mixed. If that were to happen, a subsequent analysis would no longer be able to obtain a correct depth dependency.
- depositing the drill core can also be difficult or even impossible for reasons of space. According to the present embodiment, however, the core sample is analyzed as soon as it is pulled out of the ground, so that it is not necessary to carefully deposit the entire core sample.
- a plurality of measurements preferably 10 to 50 measurements per second, is preferably carried out during the extraction of the core sample from the soil.
- the core sample can be analyzed with a high spatial resolution, so that the elemental composition can be determined with a correspondingly high-resolution depth dependency.
- other parameters of the soil can be determined, for example using optical cameras, infrared analysis, NIR, Radar measurement, microwave measurement, ultrasound measurement and / or gamma ray backscatter and absorption.
- a device for determining an element composition of a soil as a function of the depth comprises:
- a LIBS device for determining the elemental composition of the soil as a function of the depth by analyzing the core sample removed by means of laser induced breakdown spectroscopy, LIBS.
- the described particular advantages and design features of the method for determining the elemental composition of the soil as a function of the depth are applicable and transferable to the device for determining the element composition of the soil as a function of the depth, and vice versa.
- the method described is preferably carried out with the device described.
- the device described Vorrich is preferably set up to carry out the method described.
- the LIBS device is preferably set up in such a way that the core sample can be analyzed during extraction.
- a method for determining an element composition of a soil includes:
- step c) Determining the elemental composition of the soil from the results of step a) and / or b).
- step b) the special features of step b) are described in particular.
- the result of the method described is preferably a profile of the element composition of the floor.
- a profile is preferably dependent on location and depth, and to that extent three-dimensional.
- the depth dependency can be achieved through step a).
- a two-dimensional profile can also be created which is only location-dependent and includes a value for each location.
- Such a profile can also be created without step a).
- a two-dimensional profile can also be obtained, for example, by projecting the values of a three-dimensional profile.
- the profile obtained can be used, for example, to identify the pollutant concentration in anthropogenically influenced soils. This can make it easier for operators of such floors to provide the necessary official evidence.
- Environmentally relevant parameters in particular can be systematically be captured. Based on this, pressures on soil and water can be minimized.
- the profile obtained can be used to draw conclusions for the development of the soil quality, especially together with other parameters.
- steps a) and c) can be carried out without step b), steps b) and c) without step a) or steps a), b) and c).
- steps a) and b) can be carried out completely or partially at the same time or one after the other in any order.
- step c) only begins after the beginning of step a) and / or b). However, it is possible for step c) to be carried out partially or completely in parallel with steps a) and / or b).
- step a) the method described above for determining the elemental composition of the soil is carried out as a function of the depth for at least one sample location, preferably for a plurality of sample locations.
- the sample locations are preferably arranged on the basis of a grid and distributed over the entire floor.
- step b) the soil is analyzed using PGNAA and / or using PFTNA.
- the elemental composition of an upper soil layer can be obtained by means of PGNAA and / or PFTNA.
- the elemental composition can be obtained in the form of average values, which are formed, for example, over the 50 cm of the soil immediately below the soil surface.
- the Neutrons can be emitted into the ground from a neutron source, for example a suitable radioactive material. Within the soil there is an interaction between these neutrons and the nuclei of the atoms that make up the soil. In this core interaction, gamma radiation is generated, which can be detected by a radiation detector. On the basis of the detected radiation, conclusions can be drawn about the atoms in the ground. In this respect, the elemental composition of the soil can be determined. This can be done across the board by moving a corresponding device over the floor in such a way that the floor is continuously scanned. Alternatively, it is possible to take individual measurements, for example at points on a grid, and to interpolate the results.
- a scanning unit which has a neutron source and a radiation detector.
- the scanning unit is preferably brought into the vicinity of the floor surface with a slide or a lifting device and moved over it.
- the scanning unit can also be mounted on a plow so that the device can be inserted into depressions in the ground.
- the element composition of the soil is determined from the results of step a) and / or b).
- step c) takes place on the basis of the results from step a).
- the results from step a) can be supplemented, for example, by interpolation between the sample locations to form a comprehensive profile of the elemental composition. This profile can be location- and depth-dependent and thus be three-dimensional. If, in addition to step c), only step b) is carried out, step c) takes place on the basis of the results from step b).
- step c) can consist, for example, in bringing the result of step b) into the form of a seamless two-dimensional element distribution map of the soil.
- step c) the elemental composition of the soil is created based on the result of step a) and with correction based on the result of step b) or based on the result of step b) and with correction based on the result of step a).
- the advantages of the analysis methods used in steps a) and b) are combined with one another. By linking the methods, the analytical advantages of the respective method are integrated into an overall system with particularly high measurement potential. Using PGNAA and / or PFTNA, the elemental composition of the soil can already be determined across the board. In this respect it can be sufficient to use only this method.
- PGNAA and PFTNA are limited. In addition, these methods are only sensitive to certain elements. A higher measurement accuracy can be achieved with LIBS than with PGNAA and / or PFTNA. More elements can also be analyzed with LIBS than with PGNAA and / or PFTNA. However, LIBS is more complex than PGNAA and / or PFTNA due to the required sampling. An analysis of core samples using LIBS is different from an analysis using PGNAA and / or PFTNA - more information with regard to the element spectrum and the depth dependency.
- a model of the elemental composition of the soil is created using PGNAA and / or PFTNA and corrected using the LIBS, or vice versa. Correcting is understood to mean that in step c) the elemental composition of the soil is determined in such a way that - as far as possible - the values obtained with the two different measurement methods coincide with one another.
- the element composition between the sample locations determined in step c) can include values that are based on the results of the PGNAA and / or PFTNA.
- a profile of the elemental composition of the soil is created which covers the soil from a soil surface down to a depth in the range from 0.3 to 1 m.
- the specified depth coverage for many applications is a suitable compromise between the measurement accuracy, the required effort and the knowledge of the element composition required for the respective application at certain depths.
- PGNAA and / or PFTNA average values for maximum depths in the range from 0.3 m to 0.5 m can be obtained. If, together with LIBS, a profile of the elemental composition of the soil is created, this can be particularly accurate down to a depth of 0.3 m and, down to a depth of 1 m, it can be sufficiently accurate for many purposes.
- the present embodiment is particularly suitable for agricultural soils. Especially when analyzing anthropogenic influences Soils and geological exploratory boreholes using LIBS can, as described above, be relevant to significantly greater depths.
- moisture of the soil is additionally determined in step a) and / or b) and taken into account when determining the elemental composition of the soil.
- the water content in the soil can have an impact on the neutron flux through the soil. Knowing the moisture of the soil can therefore improve the accuracy of the LIBS, PGNAA and / or PFTNA.
- the moisture in the soil can be determined, for example, by means of microwave technology, near infrared technology, gamma backscattering, measurement of the capacitive resistance, or by Terra-Hz measurement technology.
- the humidity is preferably determined as a function of the depth. This can be done in particular while a core sample is being taken.
- At least one parameter of the soil is further determined by means of near-infrared spectroscopy, NIR, and / or by means of a camera.
- NIR can also be used to determine the depth-dependent additional information on the soil as a soil parameter and to compare it with the results obtained by LIBS, PGNAA and / or PFTNA.
- a corrected element composition can be determined as the overall result, for example by correcting and / or calibrating the result of the LIBS, PGNAA and / or PFTNA on the basis of the result of the NIR.
- NIR can be used to determine other parameters of the soil, such as a water content of the soil and / or a proportion of certain organic compounds in the soil. These parameters are preferably determined depending on the depth. Alternatively, it is preferred to determine these parameters independently of the temperature, for example as average values over a core sample and / or by direct analysis of the surface of the soil.
- the camera is preferably a high performance camera.
- the camera preferably has such a high resolution that properties of the soil can be determined optically.
- the camera can be used to determine soil parameters such as the cohesion of the soil, a grain size distribution pattern and / or a clay content in the soil. These parameters are preferably determined as a function of the depth, for example by analyzing a core sample.
- the core sample is preferably analyzed with the camera during removal. Thus the surface of the core sample can be analyzed without having to move the camera. Alternatively, it is preferred to determine these parameters independently of the depth, for example as average values over a core sample and / or by direct analysis of the surface of the soil.
