1)    Value of N and K2O will be lower for FYM stored for long periods in the open.
2)    Values for typical diluted slurries, pro rata adjustment for nutrient content can be made based on slurry DM.
* based on English data; European data suggests a K2O content of 8 kg/t.
ND = no data; composting can reduce the N content of manures
