Common application methods of calcium ammonium nitrate

Nitrogen fertilizer is one of the crucial fertilizers in agricultural production, among which calcium ammonium nitrate, as a nitrogen fertilizer with efficient nitrogen supply, is widely used in the growth and development of various crops. The effective component of ammonium nitrate is nitrogen, which can be quickly absorbed by crops and promote plant growth. However, the application method of ammonium nitrate directly affects its fertilizer efficiency and crop yield, so it is particularly important to apply ammonium nitrate scientifically and reasonably.

The timing of applying calcium ammonium nitrate is crucial

Generally speaking, 15245 12 2 should be applied during critical periods of crop growth, such as germination, tillering, and grain filling. These periods are when crops have the strongest demand for nitrogen, and timely application can effectively improve crop growth rate and yield. For crops sown in early spring or autumn, it is recommended to apply ammonium nitrate shortly after sowing to ensure sufficient nitrogen support for seed germination. Meanwhile, adjusting the timing of fertilization according to different weather conditions can also help better utilize the effectiveness of ammonium nitrate.

There are various methods for applying calcium ammonium nitrate, mainly including base fertilizer, topdressing, and foliar fertilizer

When used as base fertilizer, calcium ammonium nitrate fertilizer should be deeply plowed into the soil before cultivation to ensure that the fertilizer is fully mixed with the soil and avoid fertilizer waste caused by uneven application. When used as topdressing, water fertilization or drip irrigation is usually adopted in the middle and later stages of crop growth, which can effectively improve fertilizer utilization and avoid surface evaporation and leaching losses. Foliar fertilizer application is achieved by dissolving ammonium nitrate in water and spraying it onto leaves, which can quickly provide nutrients to plants and has good quick acting and targeted effects.

When applying calcium ammonium nitrate, attention should be paid to controlling the application amount

Excessive application can not only cause burns to crop roots, but may also lead to environmental problems such as eutrophication of water bodies. Therefore, a reasonable amount of fertilizer should be calculated based on soil fertility, crop types, and growth stages before application. It is generally recommended to apply an appropriate amount of fertilizer based on soil testing results and specific crop needs to achieve the best fertilizer effect.

It should be emphasized the importance of using calcium ammonium nitrate in a reasonable manner and in combination with other fertilizers

By scientifically combining ammonium sulfate calcium nitrate with other types of fertilizers such as phosphorus and potassium, a more rational nutritional structure can be formed to meet the comprehensive needs of crops. Meanwhile, please note that when applying ammonium nitrate, it should be avoided to mix it with alkaline substances such as lime to prevent the loss of nitrogen nutrition.

In summary, as a commonly used nitrogen fertilizer, the application method of calcium ammonium nitrat not only affects its fertilizer efficiency, but also directly affects crop yield and quality. Therefore, agricultural producers should scientifically select the application time, method, and amount based on specific circumstances, in order to achieve the dual goals of increasing crop yield and protecting the environment.
