There are many precision ag technologies available, but due to the complexity and cost of them, clear evidence of improved outcomes is lacking.
Evaluate the EM38 and Veris sensor-based soil mapping tools for accuracy and on-farm practicality use. Using a variety of sources to gather information on soil management zones, determine relationships between soil properties, soil moisture availability and crop yields.
The performance of EM38 and Veris soil tools were accurate and consistent. They were able to indicate the presence of clay and soil moisture but could not provide a direct estimation of spatial distribution for NPKS. The use of variable rate technology is not straight forward, rather each field is unique and requires various management strategies. Determining optimal nitrogen rates with variable rate technology was challenging due to the capacity to manage soil variability.
When developing a variable rate management strategy, more verified and effective tools must be readily available to growers. VR strategy can change per field as each field can greatly vary on its properties. Currently unable to recommend variable rate nitrogen application as a consistently effective crop management tool.
