How to Mix Chemical Fertilizer With Organic Fertilizer Scientifically?
Making the best of both fertilizers and raising soil fertility. The chemical fertilizer features single nutrient, high content, fast fertilizer efficiency and short duration; while the organic fertilizer has complete nutrient and lasting fertilizer effect , and it can improve soil and raise soil fertility. By blending the two kinds of the fertilizer, it can comprehensively supply the nutrients needed for crop growth, promote the robust growth of crops, and increase the yield-increasing benefits.
Keeping nutrients and reducing loss. The chemical fertilizer dissolves quickly and has high solubility. After it being applied to the soil, the concentration of soil solution will increase rapidly, resulting in higher osmotic pressure, affecting the absorption of nutrients and water, and increasing nutrient loss. The combination of organic fertilizer and chemical fertilizer can avoid the sudden increase of soil solution. At the same time, organic fertilizer can improve the nutrient absorption condition, increase the capacity of water storage and fertilizer retention, prevent and reduce the loss of chemical fertilizer nutrients, and improve fertilizer utilization.
Reducing nutrient fixation and improving fertilizer efficiency. After the chemical fertilizer is applied to the soil, some nutrients will be absorbed by the soil, blended or fixed, thus the fertilizer efficiency will be reduced. If the superphosphate and calcium magnesium phosphate are directly applied to the soil, they are easily combined with iron, aluminum, calcium and other elements in the soil to form a poorly soluble phosphate and fixed, resulting in available nutrient loss. By mixing with organic fertilizer, it can not only reduce the contact surface and chance of fixation of soil and chemical fertilizer, but also convert the insoluble phosphorus in the phosphate fertilizer into the effective phosphorus that the crop can use, thus improving the fertilizer efficiency of the phosphate fertilizer.
Improving soil structure and promoting continuous yield increase. Long-term single application of chemical fertilizer will destroy the agglomerate structure of the soil, causing soil viscosity and compaction, reducing tillage performance and fertilizer performance. Organic fertilizer is rich in organic matter, which can activate loose soil and reduce capacity; it can improve soil physical and chemical properties such as water, fertilizer, gas and heat; and adjust pH. The combination of the two can not only increase production, but also promote the sustainable development of agriculture.
Promoting microbial activities and increasing soil nutrients. Organic fertilizers are the energy of microbial life. Chemical fertilizers are inorganic nutrients for microbial life growth. The combination of the two promotes microbial activities, which promotes the decomposition of organic fertilizers and produces a large amount of carbon dioxide and organic acids, which contributes to the dissolution of difficulty soluble nutrient and the absorption of crops. Carbon dioxide can increase the carbon nutrition of crops and improve photosynthetic efficiency. The microbial life is short-lived, and it decomposes and releases nutrients for the crop to absorb and utilize after its death.
