Description of organic fertilizer
Organic fertilizer is a general term, it contains many sources of organic matter fertilizer, in addition to nitrogen, phosphorus and potassium necessary for plant growth, but also contains trace elements. Organic fertilizer has comprehensive nutrition, stable and lasting fertilizer efficiency, which can improve soil physical and chemical properties and biological activity, and is the main energy for soil microbial reproduction. Therefore, in order to maintain and improve soil fertility, we must add a certain amount of organic fertilizer to the soil every year.
In the early days, it was made of local materials from rural areas. It came from a variety of materials, including human and animal manure, compost, cake fertilizer, soil compost, mud fertilizer, humic acid fertilizer and crop straw. Return to fields and all kinds of organic waste. These are the traditional ways to make organic fertilizer. In recent years, in the United States, Western Europe, Japan and other emerging ecological agriculture, organic agriculture and other fields, the use of organic fertilizer as the focus, organic fertilizer as the main source of green food production. Organic fertilizer plant is widely used and plays an important role in the market. Our self-developed multifunctional organic fertilizer equipment has the advantages of compact structure, small floor area and reliable operation.
Function of organic fertilizer:
Organic fertilizer can increase soil organic matter, which is the main material basis of soil fertility, and can improve soil structure, nutrients, energy, water and air permeability. It has a great influence on microbial activity.
2. It contains a lot of nutrients and micronutrients needed by plants. The supply of nutrients is comprehensive, stable and lasting, which provides the necessary conditions for the production of high-yield, high-quality and pollution-free green food
3. Improve soil enzyme activity, improve soil water nutrient, nutrient protection and air permeability to create a good environment for plant growth.

4. Organic fertilizer decomposes in the soil to produce various humic acids and promote the activity of enzymes, the synthesis, transportation and accumulation of substances in plants. Adsorption of heavy metal ions is conducive to the production of safe and healthy green food.
At present, the following methods are the main methods to produce organic fertilizer based on different raw materials.
1. Animal excrement, animal excrement, such as chicken, pig, cow, sheep, horse, rabbit, animal residue, such as fish meal, bone meal, feather, fur, silkworm excrement, biogas residue, etc.
2. Agricultural waste. Crop straw, grapevine, soybean meal, rapeseed powder, cottonseed powder, castor seed powder, tea seed powder, yeast powder, mushroom residue, etc.
3. Industrial waste: wine residue, vinegar residue, sawdust, filter mud, herb residue, furfural residue, etc.
4. Urban sludge, river sludge, pound sludge, ditch sludge, sea sludge, lake sludge, sewage sludge, humic acid, turf, lignite, turf, organic fertilizer production line, fertilizer particles, fly ash, ash, etc.
5. Domestic waste. Kitchen garbage, etc
6. Extracted or concentrated organic matter, seaweed extract, fish extract, etc.
