Answer 2

The important concentrated organic manures are oilcakes, blood meal, fish manure etc. These are also known as organic nitrogen fertilizer. Before their organic nitrogen is used by the crops, it is converted through bacterial action into readily usable ammoniacal nitrogen and nitrate nitrogen Examples of manure include rabbit, horse, cow, and chicken poop and bat guano. Examples of fertilizers include synthetic chemical blends, minerals, and compost from decaying organic matter. Throughout history, people who raise livestock and poultry have used manure as a fertilizer, soil amendment, energy source, even construction material. Manure contains many useful, recyclable components, including nutrients, organic matter, solids, energy, and fiber.
