To build an organic fertilizer plant, raw materials must be determined first. The raw materials for organic fertilizer production are usually not commodities on the market, but wastes from some farms such as livestock manure, agricultural wastes such as straw, and various industrial wastes (mainly refers to wastes processed with agricultural products). These organic fertilizer materials have high humidity and low density of dry materials. They are easy to produce odor and pollute the environment after accumulation. For example, poultry and livestock manure, sugar mill filtrate, sludge, after a long time and will emit odor. The residues of crops after harvest, including rice straw, various kinds of cake, shells of various crops, corn cobs, etc., are lighter, but they do not taste.
Raw materials of organic fertilizer are difficult to transport, so the raw materials for organic fertilizer production can not be transported over long distances. The general transport radius range is 20-40 km. Therefore, when building an organic fertilizer plant, it is necessary to take into account the raw materials used in the production of organic fertilizer, investigate the quantity, price, sustainability of the supply of organic fertilizer raw materials, and establish cooperation with the surrounding supply points. According to the supply of raw materials to determine the production scale, determine the market demand, and then purchase organic fertilizer production line equipment.
