Variable Rate Potassium

Picture_2_Potassium

Picture1_Potassium EDRadiometrics potassium map showing the variation in gamma potassium % from low (red) to high (grey), this variation will then be ground truthed by soil coring to determine the correlation between radiometrics potassium and plant available colwell potassium.


Picture_3_Potassium

Results of soil coring show a strong correlation between radiometrics potassium and colwell potassium at an 87% accuracy that now allows us to build a variable rate potassium application map that targets the area most in need of muriate of potash.

Results of soil coring show a strong correlation between radiometrics potassium and colwell potassium at an 87% accuracy that now allows us to build a variable rate potassium application map that targets the area most in need of muriate of potash.
