Compost amendments not only have fertiliser benefits but can also increase soil organic matter, improve water-use efficiency and suppress disease. Manure composition varies with animal type, age, feed ration and the environment. Compost is a dark, crumbly, earthy-smelling material produced by the natural decomposition of leaves, grass clippings, and many other organic materials. Compost contributes relatively stabilized carbon (C) while cover crops provide readily degradable (labile) organic matter. The Many Benefits of Compost. As a soil amendment compost is excellent, improving both clay and sandy soils, increasing water holding capacity, and enhancing plant growth. Application of organic matter to the soil adds carbon, which promotes the growth of beneficial bacteria, which increases the likelihood of hearty plants. If you’re using unfinished (raw) organic matter like leaves or undecomposed manure, add it to your soil at least one month before planting. Compost and cover crops are often used to add organic matter to the soil in these systems. <>
