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)
The equipment of the organic fertilizer production line is actually an environmentally friendly product, and the raw materials used for organic fertilizer are also sourced from local organic waste. The raw materials include crop straw, farm manure, humic acid, furfural residue, vegetable waste, orchard waste branches, soybean meal, and other raw materials. These agricultural and aquaculture waste can be processed by organic fertilizer production equipment to produce organic fertilizers that are beneficial to our fields, This solution not only allows local materials to be sourced, but also saves costs for enterprises, and effectively helps local relevant departments alleviate environmental pressure. I believe everyone is familiar with the nutritional components contained in organic fertilizers, which have strong fertilizer effects and can effectively alleviate a series of situations such as soil compaction and the dissipation of soil microbial communities. Long term application of organic fertilizers is a necessary measure to maintain a virtuous cycle of agricultural ecology in China.
