What does organic fertilizer do What does organic fertilizer do?

Organic fertilizer, commonly known as farmhouse fertilizer, refers to a slow-acting fertilizer that contains a large amount of biological matter, animal and plant residues, excrement, biological waste and other substances. Organic fertilizer not only contains a large number of essential elements and trace elements for plants, but also contains rich organic nutrients, and organic fertilizer is the most comprehensive fertilizer. The role of organic fertilizer in agricultural production is mainly manifested in the following aspects:

1. Improve the soil and fertilize the soil. After organic fertilizer is applied to the soil, organic matter can effectively improve the physical and chemical status and biological characteristics of the soil, mature the soil, enhance the fertilizer retention capacity and buffer capacity of the soil, and create good soil conditions for the growth of crops.

2. Increase output and improve quality. Organic fertilizers are rich in organic matter and various nutrients that provide nutrients to crops. After the organic fertilizer is decomposed, it provides energy and nutrients for soil microbial activities, promotes microbial activities, accelerates the decomposition of organic matter, and produces active substances that can promote the growth of crops and improve the quality of agricultural products.

3. Improve the utilization rate of fertilizer. Organic fertilizer contains more nutrients but relatively low content and is released slowly, while chemical fertilizer has high nutrient content per unit and few components and is released quickly. The organic acids produced by the decomposition of organic matter can also promote the dissolution of mineral nutrients in soil and chemical fertilizers.

Organic fertilizer and chemical fertilizer promote each other, which is conducive to crop absorption and improves the utilization rate of fertilizer.

It's not complicated, it's easy to learn, and you will be given a set of technical information, and you will learn it as soon as you learn it.

The raw materials for the production of organic fertilizer are divided into five categories, one is agricultural waste (such as straw, soybean meal), the second is livestock and poultry manure (such as chicken manure, cow manure), the third is industrial waste (such as distiller's grains, vinegar grains, sugar residue), the fourth is domestic garbage, kitchen waste, and the fifth is urban sludge (such as river sludge and sewer sludge). Organic fertilizer can increase and renew the organic matter in the soil, which can provide comprehensive nutrition for crops.

1. What is organic fertilizer made of?

1. The raw materials for the production of organic fertilizer are divided into five categories, one is agricultural waste (such as straw, soybean meal, cotton meal), the other is livestock and poultry manure (such as chicken manure, cattle, sheep and horse manure, rabbit manure), the third is industrial waste (such as distiller's grains, vinegar grains, cassava residue, sugar residue, furfural residue), the fourth is domestic garbage, kitchen waste, and the fifth is urban sludge (such as river sludge and sewer sludge). Organic fertilizers include a variety of organic acids, peptides and rich nutrients including nitrogen, phosphorus and potassium.

2. Organic fertilizer can increase and renew the organic matter in the soil, provide comprehensive nutrition for crops, and have long fertilizer efficiency, promote the reproduction of microorganisms, improve the physical and chemical properties and biological activity of the soil, and is the main nutrient for the production of green food. It is mainly used as a means to improve the physical and chemical properties of the soil, promote the growth of plants and the circulation of the soil ecosystem.

Second, the introduction of the types of organic fertilizer.

1. Composting. Compost is mainly a kind of fertilizer made of various types of fallen leaves, orange stalks, animal and plant residues, grass, human and animal manure as raw materials, mixed with each other or mixed with a small amount of soil for aerobic fermentation and decomposition in a certain proportion.

2. Manure. The raw materials used for manure are basically the same as for compost, but fermentation is carried out under flooded conditions.

3. Manure. Manure is a fertilizer made from manure and straw bedding of livestock and poultry such as horses, sheep, pigs, cows, chickens, ducks, etc.

4. Biogas fertilizer.

Biogas fertilizer is a by-product of biogas produced by the decomposition of organic matter in a sealed biogas digester, including residue and biogas liquid.

5. Green manure. Green manure is the use of wild or cultivated green plants as fertilizer, such as leguminous broad beans, mung beans, field cyanine, grass and trees, vetch, alfalfa, etc. Non-leguminous green manure includes fertile field radish, ryegrass, manjianghong, small sunflower seed, water hyacinth, water peanut, etc.

6. Crops and crop straws.

Crops and crop straw are one of the important fertilizer varieties, which contain the essential nutrients of crops such as P, N, CA, K, S, etc.

7. Pure natural mineral fertilizer in the pre-material fertilizer.

Pure natural mineral fertilizers include phosphate rock powder, potassium mineral powder, natural potassium and magnesium sulfate fertilizer, calcium chloride and other natural substances that have not undergone chemical processing. These products need to be certified organic and produced in strict accordance with organic standards before they can be used in organic farming.

8. Mud. Mud fertilizer is unpolluted pond mud, river mud, port mud, ditch mud, lake mud, etc.

9. Cake fat. Cake fertilizer is the residue cake formed by the seeds of various plants after oil extraction, such as cottonseed cake, rapeseed cake, sesame cake, bean cake, castor cake, tea seed cake, etc.

<> organic fertilizer is a kind of fertilizer used for fertilizing crops, and its functions are: improving the physical and chemical status and biological characteristics of the soil, increasing the fertilizer retention capacity, fertilizer supply capacity and buffering capacity of the soil; Improve the yield and quality of crops, improve the utilization rate of crops to other fertilizers, etc.
