Any good garden compost may appropriately be used for soil drainage and fertility.
Given
Any good garden compost GGC → SDF may appropriately be used for soil drainage and fertility.
The best compost is 40 to BC → 40-60% + DB 60 percent organic matter and is dark brown in color.
However, compost that SA → ~SDF emits a strong ammonia SA → ~D smell should not be used for drainage and fertility, for that smell means that the organic matter has not sufficiently decomposed.
