The Promotion of Organic Fertilizer to Crops and Chemical Fertilizers

1, According to the relevant data to confirm our actual production of chemical fertilizer utilization rate is only 30% to 45%. Part of the lost fertilizer is decomposed and released into the atmosphere, part is lost with the soil and water, and part is fixed in the soil and cannot be directly absorbed and used by plants, and it also causes undesirable consequences such as soil salinization and slabbing. When we apply organic fertilizer, its beneficial biological activities can improve the soil structure and increase the soil's ability to retain water and fertilizer, thus reducing the loss of nutrients. Together with the effect of organic matter beneficial microorganisms to solve phosphorus and potassium, it can increase the effective utilization rate of chemical fertilizer to more than 50%.

2, Organic fertilizer can increase crop yields, improve the quality of agricultural products In the same nutrient conditions, organic fertilizers compared with chemical fertilizers, in the application of fertilizers for the base, organic fertilizers are generally better than chemical fertilizers, in the application of fertilizers for follow-up, after full decomposition of organic fertilizers, the effect is often better than chemical fertilizers. Especially to improve the quality of agricultural products than chemical fertilizers more favorable. Chinese farmers have a tradition of using organic fertilizers, attach great importance to the use of organic fertilizers. The United States, Western Europe, Japan and other developed countries, is the rise of "ecological agriculture" "organic agriculture", attach great importance to the use of organic fertilizers, and organic fertilizers as the main source of fertilizer for the production of green food.

3, Organic fertilizer can promote the growth of soil microorganisms, promote crop absorption and utilization Organic fertilizer contains a large amount of organic matter, is the best place for the growth and reproduction of various microorganisms. The organic matter of organic fertilizer can also produce various phenols, vitamins, enzymes, growth hormones and hormone-like substances in the process of decomposition, which promote the growth of crop roots and the absorption of nutrients.

4, Reduce nutrient fixation, improve the effectiveness of nutrients.Organic fertilizers contain many organic acids, humic acids and other hydroxyl substances, which have strong chelating ability and can chelate with many metal elements to form chelates, which can prevent the soil from failing to fix these nutrients. Such as organic fertilizer and phosphorus fertilizer mixed application, organic fertilizer in the organic acid and other chelates can be very active in the soil chelate aluminum ions, can prevent the combination of aluminum and phosphorus to form a crop is difficult to absorb the closed state phosphorus, greatly improving the soil effective state phosphorus content.
