What should be noted when applying organic fertilizer (farmyard manure)? Please give guidanceZhongdi Web has compiled the precautions to note during the use of organic fertilizer (farmyard manure), listed below for netizens' reference.
Note 1: Organic fertilizer (farmyard manure) needs to be applied in proportion:
For the scientific and technological knowledge of organic fertilizer being beneficial to crop growth, reasonably combine biological bacterial fertilizer with farmyard organic fertilizer, mineral fertilizer and chemical fertilizer, adhere to the "four-in-one" balanced fertilization formula technique, and guide fertilization according to the nutritional needs of the crop growth period. Practice has proven that the best ratio is 1-2% biological bacterial fertilizer, 50-60% organic matter fertilizer, 10-20% medium and trace element fertilizer, and 30-40% major element fertilizer of nitrogen, phosphorus and potassium, and the yield increase effect can obviously rise by 20-30%.
Note 2: Organic fertilizer (farmyard manure) can only be used after being decomposed and fermented:
Organic biological fertilizer can activate the soil, improve the soil, strengthen the disease resistance, insect resistance and disaster resistance of crops, and can improve crop quality and increase yield. But organic fertilizers such as poultry and livestock pens, human and animal manure, and cake meal in nature must be fully decomposed and fermented before application.
After fermentation, first, the acidity in the organic fertilizer is balanced, the nitrate content is reduced, and moisture is replenished, which is beneficial to the combined use of microbial bacteria in natural soil; second, after fermentation, it can kill parasite eggs and harmful biological pathogens in the original manure, and the pathogens and damage directly brought to crops and soil.
Note 3: Organic fertilizer (farmyard manure) should be applied as base fertilizer after deep tillage as much as possible:
Improve the fertilization method. First, apply organic fertilizer deeply or cover it into the soil as much as possible, avoid the phenomenon of spreading fertilizer on the surface, and reduce fertilizer loss, waste and environmental pollution;
Second, the base fertilizer at the crop seedling stage should be applied deeply or early, especially strictly control the application amount of nitrogen fertilizer at the crop seedling stage;
Third, fertilization should be carried out according to the law of crop growth nutritional needs. Generally, crops with a short growth period can be applied as base fertilizer all at once. For cotton cultivation with a long growth period, fertilization should be applied in early and late stages, that is, "light early, heavy late" for reasonable application, so as to achieve the expected target yield effect.
Note 4: Apply in combination with biological organic bacterial fertilizer:
In actual production, poor organic matter in the soil easily causes disease and insect damage to crops and low yield. Applying more organic matter fertilizer can not only improve crop yield and quality, but also give crops the ability to resist drought, resist premature aging and resist pests and diseases. In particular, the combined use of organic fertilizer and biological bacterial fertilizer can give the soil better functions of nitrogen fixation, phosphorus solubilization and potassium solubilization, play a role in improving the soil, improving fertilizer utilization rate, and achieving the effects of saving costs, increasing yield and increasing income.
