The final product from the composting process that has been sanitised and stabilised, is high in decomposed organic material and can be beneficially applied to land generally to improve soil structure rather than as a fertiliser, because it is normally low in plant nutrients.

It is used in agriculture and gardening, when properly prepared, it is free of obnoxious odours. Composts commonly contain about 2% nitrogen, 0.51% phosphorus, and about 2% potassium. Lime and nitrogen fertilisers and manure may be added to speed decomposition. The nitrogen of compost becomes available slowly and in small amounts. Because of their low nutrient content, composts are usually applied in large amounts.
