Anhydrous ammonia agriculture application in improving crop growth

Anhydrous ammonia is a nitrogen-containing compound with the chemical formula NH₃. It is mainly used to make nitrogen fertilizers, refrigerants, pharmaceutical products and chemical raw materials. Because of its high nitrogen content, it has become an important high-quality nitrogen fertilizer in agricultural production.

Anhydrous ammonia agriculture application is mainly reflected in replenishing nitrogen in the soil, providing sufficient nutrients for crops, and ensuring its high-yield and high-quality growth process. In addition, anhydrous ammonia can also be used to improve the soil environment, promote the growth of soil microorganisms, enhance soil fertility, and be beneficial to the healthy growth of crops. This article will focus on anhydrous ammonia agriculture application in improving crop growth.

Most of the world's ammonia is used as fertilizer in its salt, solution or anhydrous form. When applied to soil, it helps increase the yield of crops such as corn and wheat. The annual application of anhydrous ammonia worldwide is 110 million tons. Anhydrous ammonia can be used to produce nitric acid, urea and other chemical fertilizers, and can also be used as a raw material for pesticides.

Anhydrous ammonia agriculture application in improving crop yield and quality

Nitrogen is an essential nutrient element for plant growth and has a very important impact on crop yield and quality. It is precisely because of the high-efficiency nitrogen contained in ammonia that it plays an important role in supplementing soil nitrogen and improving crop yield and quality.

In practical applications, anhydrous ammonia can increase the protein content of crop roots and leaves, promote crop growth and fertility, and ensure crop yield and quality. Especially for some crops that require a large amount of nitrogen supply, such as rice, corn and wheat, the application of anhydrous ammonia can achieve a significant increase in yield.

Anhydrous ammonia can also be used in agricultural production to improve soil pH and fertility, promote the growth of soil microorganisms, optimize soil structure and increase water storage capacity, which is beneficial to the healthy growth of crops and increased yield and quality.

In addition, appropriate application of anhydrous ammonia can also lower the pH value of the soil, making it more suitable for plant growth and improving the plant's ability to absorb other elements. Therefore, in agricultural production, the application of anhydrous ammonia plays a positive role in promoting and improving soil and crop growth.

Application amount and principles of anhydrous ammonia agriculture application

The ammonia concentration of agricultural anhydrous ammonia fertilizer is generally controlled within the range of 15% to 18% nitrogen content, and the carbonization degree is greater than 100%. Fertilization is simple and easy, and there are many methods, such as furrow application, surface application, application with irrigation water or spray application. When using, it must be diluted with water to less than one thousandth, and avoid contact with stems and leaves to avoid burns.

The principle of application of anhydrous ammonia fertilizer is not to leave the soil or water. Not leaving the soil means applying the soil deeply; not leaving the water means adding water to dilute it to reduce the concentration and volatilization, or combine it with irrigation.

Since anhydrous ammonia is less dense than water, care should be taken during irrigation to avoid excessive accumulation in local areas and burning the plants. Anhydrous ammonia can be used as base fertilizer or top dressing.

The commonly used agricultural anhydrous ammonia concentrations in China are 15%, 17% and 20% ammonia. The concentration of agricultural anhydrous ammonia abroad is slightly higher, generally products containing 25% anhydrous ammonia and 20% nitrogen.

In summary, anhydrous ammonia agriculture application is widely, anhydrous ammonia is an important high-quality nitrogen fertilizer in agricultural production, which can increase crop yield and quality, while also improving the soil environment and promoting the healthy growth of crops. For modern, efficient and sustainable agricultural production, the application of anhydrous ammonia is of great significance.
