Organic fertilizer and soil improvement technology

At present, China, like developed countries, is promoting the development of “ecological agriculture” and “organic agriculture” and advocates the importance of using organic fertilizers. The application of organic fertilizers can improve the soil. Fruit tree production should also pay attention to the use of organic fertilizers, so that the orchard soil can be improved, so that the fruit trees can be produced with high yield and good results.


Organic fertilizers can improve soil, improve soil fertility, increase yield and improve quality. These effects can be further improved after application with chemical fertilizers. The main substance in organic fertilizers is organic matter, and the application of organic fertilizers increases the organic matter content in the soil. Organic matter can improve the physical, chemical and biological properties of the soil, ripen the soil, and fertilize the soil. The slang of “the soil depends on manure and the seedlings depend on the dung” in rural areas in China also reflects the effect of applying organic fertilizer to improve the soil to a certain extent.


The application of organic fertilizer not only increases many organic colloids, but also decomposes many organic substances into organic colloids by the action of microorganisms, thus greatly increasing the soil adsorption surface and producing a lot of adhesive substances, which make the soil particles cement and become stable agglomerates. The structure improves the soil water retention, fertilizer retention and ventilation properties, as well as the ability to regulate soil temperature, and plays a role in improving the soil.


The application of low-level organic fertilizer, or low-level organic fertilizer combined with nitrogen fertilizer, the phosphorus in the soil is deficient. Only the application of high-volume organic fertilizer, and the combination of high-content organic fertilizer and chemical fertilizer, the phosphorus in the soil has a surplus, and the available potassium increases. The application of organic fertilizer is very important for the balance of phosphorus and potassium in soil. Explain that to improve the soil, organic fertilizer should be applied in high amounts.


The application of organic fertilizer can also cause the microorganisms in the soil to multiply, especially many beneficial microorganisms, such as nitrogen-fixing bacteria, ammoniating bacteria, cellulose-decomposing bacteria, nitrifying bacteria and the like. Organic fertilizers contain various active enzymes secreted by the digestive tract of animals, as well as various enzymes produced by microorganisms. When these substances are applied to the soil, the enzyme activity of the soil can be greatly improved. The application of organic fertilizer can improve the soil activity and the ability of biological reproduction and transformation, thereby improving the absorption capacity, cushioning and stress resistance of the soil, and also improving the soil.
