According to primary and secondary
(1) Main raw materials. The main raw material of organic fertilizer production process accounts for 30% – 80% of the whole material, which is composed of one or several raw materials. The main materials commonly used are animal manure, straw powder, mushroom residue and so on.
(2) Accessories. It is mainly used to adjust moisture, carbon nitrogen ratio, pH value and permeability of some raw materials, composed of one or several raw materials. Usually, this kind of raw material accounts for less than 40% of the whole material, and the proportion of single material is less than 20%. The commonly used auxiliary materials are wheat bran, soybean meal, peat, plant ash, quicklime, etc.
Classification by raw material properties
According to the properties of raw materials, it can be divided into carbon containing raw materials, nitrogen containing raw materials and conditioner raw materials.
(1) Carbonaceous materials. It refers to the raw materials with high organic carbon content, which are usually used as main composting materials, such as straw, rice husk, mushroom residue, etc. In addition to straw composting, most of the carbonaceous materials are used as auxiliary materials to adjust water content, carbon nitrogen ratio, bulk density and enhance the permeability of materials.
(2) Nitrogen containing raw materials. Generally refers to the raw materials with carbon nitrogen ratio below 30:1, such as livestock manure. There are also some high nitrogen raw materials used as auxiliary materials to adjust the carbon nitrogen ratio, such as soybean meal, fish meal, etc.
(3) Conditioner raw materials. It mainly refers to raw materials used to adjust pH value, such as quicklime to adjust acidity and gypsum to adjust alkalinity. Sometimes the raw materials used to adjust the C / N ratio are summarized as regulators, such as superphosphate, phosphate rock powder, etc. .jpg)
Small organic fertilizer equipment worth around 11000 yuan is highly welcomed by ordinary farmers. There are many raw materials for organic fertilizer, such as livestock and poultry manure, agricultural waste, plant ash, mushroom residue, etc. The majority of livestock and poultry manure is treated, many of which are owned by farmers. Small organic fertilizer production lines can meet this requirement, not only solving the problem of emission reduction and disposal of livestock and poultry manure, but also making money from livestock and poultry manure, bringing significant profits.
