(1) Nutrients that are available to the next crop.
(2) Nitrogen and potash values will be lower if FYM is stored in the open or for long periods.
(3) Adjust nutrient content if % DM is higher or lower.
 
Imperial Conversions

Multiply kg/m3 by 9 to give units/1000 gals
Multiply kg/t by 2 to give units/ton
