Soil EC (CEC/Texture)
What does this map mean?
Soil texture—the amount of sand-silt-clay—is directly related to water holding capacity, nitrogen use and loss, and is the primary driver of productivity. Cation-exchange capacity (CEC) is typically highly correlated with texture. Because CEC is a commonly available soil lab test, Veris EC data can be calibrated to CEC values.
Soil electrical conductivity has quickly become a favorite tool in mapping soil variability with fields.”

How can this map be used?
Here’s a partial list of the ways Veris EC maps are being used: zone sampling, variable seeding, improved nitrogen management, variable irrigation, variable soil herbicides, salinity remediation, site-specific gypsum and other amendment applications, yield and crop image interpretation, and more.
When coupled with other soil sensors and topography, the applications for EC data are even more powerful.
Sensor data quality is high, with over 80 points per acre.
Zones of contrasting soil are clearly evident, even in viewing raw sensor data maps.
