Organic manure, a nutrient derived from organic sources like waste of animals, vegetable compost, agricultural residues, human excreta, etc. They are basically a natural material that will decay and get mixed with the soil help in higher fertility. Plants need simpler organic supplements and Organic manure play the role of breaking down the complex inorganic nutritional supplement into simpler organic ones. Organic manure raises the soil's organic matter. Organic matter in effect releases usable plant food from crop use. Organic manures, however, should not be seen exclusively as plant food carriers. Such manures often allow a soil to hold more water and help improve drainage in clay soils as well. They provide organic acids that help dissolve nutrients in the soil and make them available to the plants.
