Organic fertilizers and chemical fertilizers are used in combination to complement each other. However, if they are not combined properly, they will cause both injuries and damage.
First, the benefits of organic fertilizer and fertilizer application
1, complement each other, fertility and fertility. Fertilizer has a single nutrient, high content, fast fertilizer effect, but short duration; organic fertilizer has complete nutrients and lasting fertilizer effect, can improve soil and fertility. The combination of the two can be used to make up for shortfalls, fully supply the nutrients needed for crop growth, promote robust growth of crops, and increase yield benefits.
2. Preserve nutrients and reduce losses. Fertilizer dissolves fast and has high solubility. After being applied to soil, the concentration of soil solution will increase rapidly for a time, causing higher osmotic pressure, affecting the absorption of nutrients and water by crops, and increasing the loss of nutrients and opportunities. Mixed use of organic fertilizer and chemical fertilizer can overcome the shortcomings of the sudden increase of soil solution. At the same time, organic fertilizer can improve the absorption conditions of the crop nutrients, improve soil water storage and fertility, prevent and reduce the loss of fertilizer nutrients, improve fertilizer utilization.
3, reduce nutrient fixation, improve fertilizer efficiency. After the fertilizer is applied to the soil, some of the nutrients will be absorbed by the soil, rubbed or fixed, and the fertilizer effect will be reduced. Such as superphosphate and calcium magnesium phosphate fertilizer applied directly to the soil, easy to combine with the iron, aluminum, calcium and other elements in the soil to generate insoluble phosphate and fixed, resulting in effective nutrient loss. If mixed with organic fertilizers, not only can the contact with the soil reduce the chances of fixation of the soil and fertilizers, but also the insoluble phosphates in the phosphate fertilizers can be converted into available phosphorus for crops to increase the fertilizer efficiency of the phosphate fertilizers.
4. Improve soil structure and promote continuous production increase. Long-term single application of chemical fertilizers will destroy the granule structure of the soil, resulting in soil viscous heavy consolidation, reducing the cultivation performance and fertilizer performance. Organic fertilizer is rich in organic matter, which can activate loose soil and reduce the capacity; it can improve the physical and chemical properties of soil such as water, fertilizer, gas, and heat; it can adjust the pH value. Mixing the two will increase the output and promote the sustainable development of agriculture.
5. Promote microbial activities and increase soil nutrients. Organic manure is the energy source for microbial life. Fertilizer is an inorganic nutrient for microbial growth. The combination of the two promotes microbial activity, which in turn promotes the decomposition of organic manure, produces large amounts of carbon dioxide and organic acids, and contributes to the dissolution of insoluble nutrients in the soil. . Carbon dioxide can increase crop carbon nutrition and increase photosynthetic efficiency. Microbial life is short-lived. After death, the nutrients are decomposed and released for the absorption and utilization of crops.
Second, suitable for mixing organic fertilizer and fertilizer
1, manure, compost and superphosphate or calcium magnesium phosphate fertilizer mix. The application of superphosphate and calcium magnesium phosphate fertilizers with manure, compost, manure, and mixed stacking not only reduces the contact surface between phosphate fertilizer and soil, but also avoids the fixation of phosphate ions in the soil, and various organic acids produced by decomposition of organic fertilizers can promote The phosphorus fixed by the soil is released for crop absorption and the fertilizer effect can be increased by one third.
2, manure, compost and ammonium bicarbonate and urea mixed application. The addition of 0.5 to 1% of ammonium bicarbonate (or acid) and human waste to manure and compost is beneficial to microbial reproduction and activities, promotes the decomposition of organic manure and release of various nutrients, and provides the crop with abundant nutrients.
3, human waste and superphosphate or calcium magnesium phosphate fertilizer mixed. Excessive content of ammonium carbonate in human fecal urine is easily lost due to volatilization. It is mixed with superphosphate or calcium magnesium phosphate fertilizer. It can form stable ammonium dihydrogen phosphate through chemical reaction, which reduces nitrogen in human fecal urea. Loss of phosphorus, but also increased phosphorus nutrition. Phosphorus nitrogen retention, fertilizer efficiency increased significantly.
4, human waste and ferrous sulfate mixed application. Adding 0.5% of ferrous sulfate to human feces and urine can make ammonium carbonate, which is highly volatile in human waste and urine, convert to ammonium sulfate with stable properties, and it can protect fat and deodorize and prevent the loss of nitrogen from evaporation.
Third, unfavorable mix of farmyard fertilizer and fertilizer
1. The unripe farmyard fertilizer cannot be mixed with nitrate nitrogen fertilizer. If mixed, the denitrifying bacteria in the farmyard manure will denitrify the nitrate nitrogen fertilizer and generate nitrite, causing nitrogen loss and reducing crop quality.
2, plant ash can not be mixed with nitrogen fertilizer application. Ash is an alkaline fertilizer. If it is mixed with ammonia nitrogen, nitrate nitrogen, and other acidic nitrogen fertilizers, neutralization and decomposition reactions will occur, releasing ammonia volatilization, causing loss of nitrogen and reducing fertilizer efficiency.
3, plant ash can not be mixed with superphosphate. Plant ash contains more calcium. If it is mixed with superphosphate, it will generate insoluble calcium phosphate, so that phosphorus can be fixed and crops can not be directly absorbed and utilized.
4, plant ash can not be mixed with manure, compost, human waste. Plant ash is generally used as potash fertilizer and is alkaline. If it is mixed with manure, compost, and human waste, it will accelerate the loss of nitrogen in the form of ammonia.
