Hello all,
I use sensors to measure nitrogen, potassium and phosphor in agricultural soil. Normally, laboratorium tests would be done to measure this. But we use npk sensors. These NPK sensors measure in mg/kg and we are used to fertilizing our soil with data in kg/hectare. So we convert mg/kg to kg/hectare.
We use the following formula for this:
Nitrogen (kg/ha) = (Nitrogen concentration (mg/kg) x Bulk density (kg/m³)x measure depth in cm)/10
This is the way the laboratorium would also convert mg/kg to kg/hectare.
But I question the accuracy of this conversion and am wondering if we can blindly trust this way of converting. We do know our sensors are accurate....
Does anyone have advice for me or experience in this field?
Thank you for your time!
