Why does FOM often fail spec, and what fixes it?
sourced
FOM frequently misses the nitrogen and potassium minimums, because digestion conserves carbon but not always nutrients, and fibrous material fails the 4 mm sieve test at 70% moisture. Enrichment with N and K - moving toward PROM - fixes the nutrient gap; proper drying and screening fix the physical one.
