Fresh manures from cattle and other ruminant animals, goats and sheep amongst the most common, contain cellulose decomposing bacteria along with active digestive enzymes. These enzymes contribute to faster heating of the manure which accelerates the decomposition of organic materials by the soil microorganisms. The end result of better decomposition of organic material is faster nutrient release to the plant.
While cow manure is excellent for growing vegetables it is not recommended to use fresh manure directly on the growing area because they will burn tender plant roots. It should instead be either;
- Applied to an area for future use as sheet compost
- Dug into the garden and allowed to age for at least 30 days
- Composted in a conventional compost heap
