CropMetrics provides complete and professional multi-layer GIS (Geographic Information System) Data Processing to fulfill the timely requirements of our local CropMetrics Precision Partners. Time is critical in accomplishing important daily activities and sitting behind a computer processing data can cost valuable time; time that is often very difficult to track. CropMetrics utilizes a world class processing facility to quickly and efficiently process raw data to benefit our Precision Partners current agronomic programs without delay.
Utilizing the Virtual Agronomist software, Advanced Data Analysis can be performed and delivered with quality reporting to begin building a sound precision ag management program. All data and reports are available through the new VA Gateway desktop applications to complete the entire process. With a focus on quality and efficient large-scale GIS Data Processing, Virtual Agronomist provides agronomists and crop consultants a turnkey solution for all their data management needs.
As part of the Virtual Agronomist base management program, CropMetrics provides complete and professional processing of the following critical agronomic spatial data layers:
EM/EC – For true precision, each field requires either EM (electromagnetic) survey or Veris EC (electrical conductivity) data collection. EM mapping helps to better characterize the variability of soil properties with respect to agronomic significance, e.g., water holding capacity, nutrient use efficiency and yield production potential. EM surveys use EM sensors mounted on sleds to generate a constant electromagnetic field that penetrates into the soil profile and measures bulk electrical conductivity via electromagnetic induction at both shallow (0-1′) and deep (0-3′) soil depth ranges. Sleds are pulled back and forth across the surveyed field at 60’ to 90’ transects with data points recorded every one-second.
Once collected, the raw field data can then be processed using spatial interpolation across the entire field. Differences in EM survey readings indicate a response to changes in relative combinations of soil textures, i.e., sand, silt and clay. The lower the EM values the lighter the soil. The higher the EM values the heavier the soil.
Landscape Change – As EM surveys are conducted; accurate, quality RTK (Real Time Kinematic) elevation data should also be recorded. The elevation layer itself is not informative; however, this layer becomes the basis for the generation of precise topographic derivatives. Slope, aspect, depression and Landscape Change are derived from this quality elevation data. These topographic derivatives have a direct effect on surface water drainage and, in turn, correlate directly with yield.
Both EM and Landscape Change are “fixed” agronomic data layers that will not change year-after-year. Therefore, the raw data only needs to be collected and processed one-time and then becomes the foundation for all precision prescription generation and Advanced Data Analysis.
Yield – Yield data is the final measurement to gauge field production. However, to make yield data valuable, it needs to be analyzed and not simply printed out to a map. Yield data is easily converted into spatial revenue, nutrient removal, water use, etc. When overlaid and analyzed in combination with EM/EC and elevation derivatives, it becomes a valuable management tool. This combination, along with knowledge from all involved with the crop development, helps the grower focus more directly on what causes the yield variability and how to best deal with it.
Imagery – CropMetrics can optionally process in-season satellite and aerial imagery (orthophotos) data to improve crop monitoring decisions during the growing season. In-Season Imagery can be easily integrated into the Virtual Agronomist software on a routine basis and at any point in the season. For in-season application of nitrogen fertilizer, Variable Rate Fertigation prescriptions derived from real-time imagery analysis and variable yield potentials of center pivot management zones in the form of pie-sliced sectors can be added at any time as an optional precision management service.
