What are the 5 steps in preparing organic fertilizer? ›

Technological Process of Biological Organic Fertilizer Production: Selection of the raw material (animal manure, sludge, industrial waste, etc.) — drying and sterilization — mixing ingredients — granulation — cooling and screening—weighting and packaging—finished product storage.

The main organic fertilizers are, peat, animal wastes, plant wastes from agriculture, and treated sewage sludge.

Indeed, organic liquid fertilizer is obtained after only 14 days of aerobic biological decomposition of a mixture of organic matter, water, and other locally available elements. This fertilizer is rich in nutrients and must be diluted before application in fields or gardens.

Supplying needed nutrients for crop production involves attention to four major fertilization factors (the 4Rs): right rate, right source, right placement, and right timing. Attention to these factors will provide adequate nutrition for crop production while minimizing the risk of loss of nutrients to the environment.

The ammonia is used to make nitric acid, with which it is then mixed to produce nitrate fertilizers such as ammonium nitrate (AN). Ammonia may also be mixed with liquid carbon dioxide to create urea. Both these products can be further mixed together with water to form UAN (urea ammonium nitrate) solution.

Nitrogen (N) is made available to the plant from the air and soil. But most of the needed elements that are nutrients for plants come from the soil. They are not all equally important but all play a role in plant growth. Most needed are nitrogen (N), phosphorus (P), potassium (K), and sulphur (S).
