Raw material compounding and mixing: the formula of organic and inorganic raw materials is mixed according to different series of products. Mix well in the mixer. If the proportion is 12%, about 12 tons.

Moisture content control: add straw powder or organic materials with high C / N ratio and low moisture content. The addition amount is 6 tons of charcoal / day, 6 tons of straw carbon / day and 18 tons of straw / day. The moisture content of raw materials after treatment is 60% - 65% and the C / N ratio is 20-30. The added substance must be fully broken.

In the production process of series of special fertilizers, inorganic nutrients and concentrated organic matter and trace element minerals are added according to different soil conditions and different crops, so that the fertilizer contains a variety of nutrient elements required for plant growth, such as nitrogen, phosphorus, potassium, sodium, manganese, zinc, copper, etc. According to the formula, the nitrogen, phosphorus, potassium and fermented materials are mixed by computer and transported to the granulator for granulation. The formula of organic and inorganic raw materials is mixed according to different series of products. Mix well in the mixer. If the proportion is 12%, about 12 tons.
