Because of great amount of chemical fertilizer being applied in a fairly long period, the organic substances content in soil reduces without the neutralization of organic fertilizer. The successive application of inorganic fertilizer, can only lead to the mineralization and exhaustion of organic material, the content of which in soil decreasing steadily. The decomposition rate of free organic matter is significantly higher than that of recombinant organic matter.
1. Soil properties getting worse.
2. Bio-activity declining.
3. Causing crop failure, severe plant disease and insect pest.
4. Low utilization rates, polluting the ecological environment.
All the signs indicate that crop growth cannot live without organic fertilizer. But how could we get organic fertilizer? We can use organic fertilizer granulator to produce organic fertilizer. Livestock and poultry manure, crop straws, sludge, grass carbon and etc. are the main materials of organic fertilizer production. Organic fertilizer processing production and technological process includes the selection of the raw material (livestock and poultry manure, crop straws, sludge, grass carbon and etc.)→fermentation treatment→burden mixing→granulation→cooling and screening→measuring and cutting→product storage.
