Results of TkN,NH4,NO3,TP and K of soil water (extracted from root zone) are given in mg/l, how to convert it to NPK applied in kg per ha
We will need information about the sample size taken , for the purpose of calculation
Incomplete question
Convert to mg/kg using the mass/volume factor then multiply by the kg/ha for the required depth. The calculation requires/assumes a bulk density.
thank you al
This might help.
