Function of Organic Fertilizer

Organic fertilizer comes from plants or animals.

It is a carbon material applied to soil to provide plant nutrition as its main function.

Through the processing of biological substances, animal and plant wastes and plant residues, the toxic and harmful substances are eliminated, which are rich in a large number of beneficial substances, including a variety of organic acids, peptides and rich nutrients including nitrogen, phosphorus and potassium.

It can not only provide comprehensive nutrition for crops, but also has long fertilizer effect.

It can increase and renew soil organic matter, promote microbial reproduction, improve the physical and chemical properties and biological activity of soil, which is the main nutrient for green food production.

Organic fertilizer, commonly known as farmyard fertilizer, refers to slow-release fertilizer containing a large number of biological substances, animal and plant residues, excrement, biological waste and other substances.

Organic fertilizer contains not only a lot of essential elements and microelements, but also a lot of organic nutrients.

Organic fertilizer is the most comprehensive fertilizer.

The function of organic fertilizer in agricultural production is mainly shown in the following aspects:

1. Improve soil and fertility.

When organic fertilizer is applied to the soil, organic matter can effectively improve the physical and chemical status and biological characteristics of the soil, ripen the soil, enhance the ability of fertilizer conservation and supply and buffer capacity of the soil, and create good soil conditions for the growth of crops.

2. Increase yield and quality.

Organic fertilizer is rich in organic matter and various nutrients, providing nutrition for crops. After the decomposition of organic fertilizer, it can provide energy and nutrients for soil microbial activities, promote microbial activities, accelerate the decomposition of organic matter, and produce active substances that can promote the growth of crops and improve the quality of agricultural products.

3. Improve fertilizer utilization.

Organic fertilizer has more nutrients but lower relative content, slow release, while chemical fertilizer has higher unit nutrient content, less components and fast release. The organic acids produced by the decomposition of organic matter can also promote the dissolution of mineral nutrients in soil and fertilizer. Organic fertilizer and chemical fertilizer promote each other, which is conducive to crop absorption and improve fertilizer utilization.
