How to improve fertilizer use efficiency? How do you store it?

Fertilizer is a kind of substance that provides one or more essential nutrient elements for plants, improves soil properties and soil fertility, and is one of the material bases of agricultural production. So how to improve fertilizer use efficiency? How do you store it?

How to improve fertilizer use efficiency?

1. We will improve farmland infrastructure and enhance the capacity of water storage and conservation. In farmland construction, large water can be discharged quickly, small water can drop quickly, water can be diverted in case of drought, and water can adjust fertilizer, so that the fertilizers applied into the soil can be quickly dissolved, transformed and utilized, and the waste of environmental imbalance of water and fertilizer can be reduced.

two。 Increase the application of organic fertilizer, mixed application of agricultural fertilizer and chemical fertilizer. The nutrient content of fully mature farm manure is relatively complete, and insisting on the mixed application of chemical fertilizer and organic fertilizer can improve soil physical and chemical properties and enhance soil fertility; second, it can make the advantages of late-acting fertilizer and quick-acting fertilizer complement each other; third, it can reduce the volatilization and loss of chemical fertilizer, enhance fertilizer conservation performance, and quickly improve fertilizer supply capacity.

3. Apply fertilizer with scientific formula to avoid partial application of simple chemical fertilizer. Balanced fertilization for different soils and different crop formulations can not only prevent the antagonistic effect of excessive use of elemental chemical fertilizer, inhibit the nutritional function of other elements, but also meet the needs of different crops for different large amounts of nutrient elements. For example, potassium fertilizer should be applied to the soil with high sand content, boron fertilizer should be applied to the fields growing rape and cotton, and zinc, magnesium, molybdenum and other trace elements should be applied according to different soil quality and different crops.

4. Constantly update the fertilization technology to effectively ensure the quality of fertilization. First, we should advocate the application of high-content multi-component compound fertilizers and reduce the application of low-content compound fertilizers; second, we should actively try high-energy organic-inorganic compound fertilizers; third, we should promote organic-inorganic compound fertilizers; fourth, we should combine fertilizers with high contents of beneficial microorganisms; fifth, we should emphasize the deep application of fertilizers; sixth, we should apply liquid fertilizers at a reasonable dosage; and seventh, we should use drip irrigation to evenly apply liquid fertilizers where possible.

How to store the fertilizer?

1. Anti-moisture deterioration: such as ammonium bicarbonate is easy to absorb moisture, resulting in nitrogen volatilization loss; ammonium nitrate has strong hygroscopicity, easy caking and hydrolysis; lime nitrogen and calcium superphosphate are easy to agglomerate after moisture absorption, affecting the application effect. Therefore, these fertilizers should be stored in a dry and cool place, especially when ammonium bicarbonate is stored, the packaging should be sealed firmly to avoid contact with air.

two。 Fire prevention and sun protection: after the nitrogen fertilizer is exposed to the sun or high humidity, the volatilization loss of nitrogen will be accelerated; ammonium nitrate will decompose oxygen at high temperature, and flammable materials will burn. Do not hit the caked ones with a hammer to prevent explosion. Nitrogen fertilizer storage should avoid the sun, strictly prohibit fireworks, do not stack with diesel oil, kerosene, firewood and other items.

3. Anti-volatilization loss: ammonia and ammonium bicarbonate are easy to volatilize and should be sealed during storage. Nitrogen fertilizer and calcium superphosphate are forbidden to be mixed with alkaline substances (lime, plant ash, etc.) to prevent the volatilization loss of nitrogen fertilizer and reduce the fertilizer efficiency of phosphate fertilizer.

4. Anti-corrosion toxicity: calcium superphosphate is corrosive to prevent contact with skin and metal utensils; ammonia is strongly corrosive to copper and iron and should be stored in ceramic, plastic and wooden containers. In addition, chemical fertilizers should not be stacked with seeds, and do not use chemical fertilizers to bag seeds so as not to affect seed germination.
