Moisture is not a single target. DMR reports about 72 to 75 per cent at the end of Phase I, when drops appear between the fingers on squeezing, and 64 to 66 per cent after Phase II, when no liquid oozes even on firm squeezing.
Long method compost at spawning is different again: 68 to 72 per cent for synthetic compost and 65 to 67 per cent where horse manure was used. The farmer folder gives 68 to 70 per cent on the squeeze test on day 28. Always say which compost and which stage before quoting a moisture figure.
