What are the kinds of organic fertilizers? With an introduction to the function of machine fertilizer.

Organic fertilizer is the general name of all fertilizer sources containing a lot of organic matter. Its nutrients are relatively comprehensive, the fertilizer effect is stable and lasting, and it has obvious effect on improving the yield and quality of crops. It is a kind of important fertilizer in agricultural production. Although organic fertilizer has many benefits, it should not be overused. At the same time, attention should be paid to the combined use of inorganic fertilizer and biological fertilizer, which is more conducive to the growth of crops. So what are the kinds of organic fertilizers? What is the function? Let's get to know it.

1. Feces and urine fertilizers

Including human feces, livestock manure, poultry manure and other animal manure and so on. It is rich in organic matter and nutrient elements needed by crops, such as nitrogen, phosphorus, potassium, calcium, magnesium, sulfur and iron, which can promote plant growth and material circulation in soil ecosystem.

2. Crop straw

Crop straw is a by-product of crops. Crop straw contains essential nutrient elements such as N, P, K, Ca, S and so on. Under suitable conditions, through the action of soil microorganisms, these elements are mineralized and returned to the soil for crop absorption and utilization.

3. Green manure

Green manure is the use of all or part of green plants directly into the soil as fertilizer, is one of the traditional important organic fertilizers in China. Green manure plays a good role in providing nutrients for crops, improving soil, improving farmland ecological environment and preventing soil erosion and pollution.

4. Cake fertilizer

Various types of cake fertilizers are generally rich in organic matter, nitrogen and a considerable amount of phosphorus, potassium, as well as weight elements or trace elements. Although the nitrogen and phosphorus in cake fertilizer can not be used directly, because the content of nitrogen element in cake fertilizer is relatively small and easy to decompose, compared with other organic fertilizers, its fertilizer effect is easy to play.

5. Compost

Including barnyard manure, compost, retting and so on. Compost is a kind of organic fertilizer made from straw, weeds, leaves, peat, garbage and rural wastes, adding appropriate amount of human and animal feces and urine.

6. Biogas fertilizer

In a sealed biogas digester, the by-products of decomposition of organic matter to produce biogas, including biogas liquid and residue. It is a kind of slow and high-quality organic fertilizer, and it is an effective measure to eliminate fecal odor, eliminate pests and improve the living environment in rural areas.

7. Sea fertilizer

At present, 60 or 70 kinds of marine animals and plants can be used as fertilizers, which are mainly divided into three categories: animal sea fertilizer, plant sea fertilizer and mineral sea fertilizer. The effect of sea fertilizer is high, and the effect of increasing yield is significant, but it should be noted that the application method of sea fertilizer should be different according to the variety.

8. Commercial organic fertilizer

It is a fertilizer produced by factory processing with solid wastes rich in organic matter, such as livestock and poultry manure, animal and plant residues, and domestic waste, as the main raw materials, and adding a certain amount of other auxiliary materials and fermentation bacteria. Compared with traditional farm manure, commercial organic fertilizer has the characteristics of comprehensive nutrients, high content and stable quality.

The above is the introduction of the types and functions of organic fertilizer. In short, there are differences in the specific functions and application methods of different varieties of organic fertilizer, and its characteristics and principles must be made clear before application to avoid self-defeating.
