Organic fertilizer and chemical fertilizer can be mixed Organic fertilizer and chemical fertilizer mixed there are tricks

Now is the season of fertilizer for various crops, fertilizer and organic fertilizer as crop nutrition providers, play a vital role in this link. Many farmers want to know whether organic fertilizer and chemical fertilizer can be mixed? What about the mix? In fact, organic fertilizers and fertilizers have a knack for mixing, not all fertilizers can be mixed and matched.

What fertilizers should not be mixed

1, grass and wood ash can not be with manure, compost. Plant ash is usually used as potassium fertilizer, is alkaline, if with manure, compost, will accelerate the loss of nitrogen in the form of ammonia volatilization.

2, plant ash can not be mixed with nitrogen fertilizer. Plant ash is an alkaline fertilizer. If

The utility of mixed application of organic and chemical fertilizers

1. Give up the short and take the long, and cultivate the fertility. The nutrient of fertilizer is single, the content is high, the fertilizer effect is fast, but the duration is short; Organic fertilizer nutrients are complete, fertilizer effect is long, can improve soil, fertility. The mixed use of the two can replace the short and take the long, comprehensively supply the nutrients required for crop growth, promote the robust growth of crops, and improve the yield increase efficiency.

2. Keep nutrients and reduce loss. Fertilizer dissolves quickly and has a large solubility. After applying into the soil, the concentration of the soil solution will quickly increase for a while, resulting in a higher penetration pressure, affecting the absorption of nutrients and water by crops, and increasing the loss and opportunity of nutrients. The mixed use of organic fertilizer and chemical fertilizer can restrain the drawback of sudden increase of soil solution. At the same time, organic fertilizer can improve the nutrient absorption conditions of crops, improve the soil water storage and fertilizer retention ability, avoid and reduce the loss of fertilizer nutrients, and improve the utilization rate of fertilizer.

3, reduce nutrient fixation, improve fertilizer efficiency. After fertilizer is applied into the soil, some nutrients will be absorbed by the soil, chelate or fix, and the fertilizer efficiency will be reduced. Such as superphosphate and calcium magnesium phosphate fertilizer directly into the soil, it is easy to connect with iron, aluminum, calcium and other elements in the soil, generate insoluble phosphoric acid and be fixed, resulting in the loss of effective nutrients. If mixed with organic fertilizer, it can not only reduce the contact surface with soil, reduce the fixed opportunity of soil and fertilizer, but also convert the insoluble phosphorus in phosphate fertilizer into effective phosphorus that can be used by crops, and improve the fertilizer efficiency of phosphate fertilizer.

4, improve the soil structure, continue to increase production. Long-term single application of chemical fertilizer will damage the aggregate structure of the soil, resulting in heavy soil compaction, and reduce the tillage performance and fertilizer supply performance. Organic fertilizer contains abundant organic matter, which can activate fluffy soil and reduce its capacity. Can improve soil water, fertilizer, gas, heat and other physical and chemical properties; Adjust pH. The combination of the two can not only increase the yield, but also promote the sustainable development of agriculture.

5, reduce the amount, reduce pollution. The mixing and matching of organic fertilizer and fertilizer can reduce the amount of fertilizer application by 30%-50%, and on the one hand, reduce the pollution to the land from the use of fertilizer. On the other hand, some organic fertilizers can degrade the residues of chemical fertilizers and pesticides in the soil. Like Mu Zhinong brand "Qitian Dasheng" bio-organic fertilizer contains soil conditioners and microorganisms, which can reduce soil pollution.

6. Improve microbial activity and increase soil nutrients. Organic fertilizer is the energy for microbial life, and chemical fertilizer is the inorganic nutrition for microbial growth. The mixed use of the two can enhance microbial activity, and further enhance the decomposition of organic fertilizer, produce a large amount of carbon dioxide and organic acid, and help the insoluble nutrients in the soil to dissolve and supply crops to absorb. Carbon dioxide can increase the carbon nutrition of crops and improve the photosynthetic efficiency. Microbial life is short, after death, it decomposes and releases nutrients for crops to absorb and use.

Suitable for mixed application of organic fertilizer and chemical fertilizer

1, manure, compost and superphosphate or calcium magnesium phosphate fertilizer mixed application. The application of superphosphate and calcium-magnesium phosphate fertilizer with manure, compost, compost and compost not only reduces the contact surface between phosphate fertilizer and soil and avoids the fixation of phosphate ions by soil, but also various organic acids generated by the decomposition of organic fertilizer can promote the release of phosphate fixed by soil for crop absorption, and the fertilizer efficiency can be increased by one-third.

2, manure, compost and ammonium carbide and urea mixed application. Adding 0.5-1% ammonium bicarbonate (or acid) and human manure to the manure and compost is conducive to the breeding and activities of microorganisms, improve the maturation of organic fertilizers and the release of various nutrients, and provide abundant nutrients for crops.

3, human manure and superphosphate or calcium magnesium phosphate fertilizer mixed application. The content of ammonium carbonate in decomposed human manure is too much, which is easily volatilized and lost by single application. After chemical reaction, ammonium dihydrogen phosphate with strong properties can be formed after mixed application with calcium superphosphate or calcium magnesium phosphate fertilizer, which not only reduces the loss of nitrogen in human manure, but also increases the phosphorus nutrition. With phosphorus to protect nitrogen, fertilizer efficiency increased.

4, human excrement and ferrous sulfate mixed application. Adding 0.5% ferrous sulfate to human manure can transform the highly volatile ammonium carbonate in human manure into solid ammonium sulfate, which can protect fertilizer and deodorize and avoid nitrogen volatilization and loss.

 it is mixed with acidic nitrogen fertilizers such as ammonia nitrogen and nitrate nitrogen, neutralization decomposition reaction will occur, and ammonia gas volatilization will be released, causing nitrogen loss and reducing fertilizer efficiency.

3. Plant ash can not be mixed with superphosphate. Plant ash contains more calcium, if mixed with superphosphate, will produce insoluble calcium phosphate, so that phosphorus is fixed, crops can not directly absorb and use.

4, undecomposed farm fertilizer can not be mixed with nitrate nitrogen fertilizer. If mixed application, denitrifying bacteria in farm manure will cause denitrification of nitrate nitrogen fertilizer, produce nitrite, cause nitrogen loss, and reduce crop character.

The mixed application of organic fertilizer and fertilizer will be better, but you need to understand that some fertilizers are not properly mixed not only have no effect but also reduce the fertilizer efficiency, so be sure to remember the tips of mixing organic fertilizer and fertilizer.
