The correct application of nitrogen fertilizers is particularly important on the basis of balanced application of multiple nutrients. Several currently applied in the production of nitrogen fertilizer, the administration should note the following: Â
　　 Â
Ammonium bicarbonate: The nitrogen content is about 17 %. After being applied to the soil, the ammonium ions of the nutrient components can all be absorbed, and no harmful substances remain in the soil. It is a physiologically neutral quick-acting nitrogen fertilizer. However, ammonium bicarbonate is volatile and should not be applied shallowly. The application depth should be below 3 cm of soil layer, and the soil should be covered immediately after application and watered in time. It is also not suitable for application in greenhouses. Because the temperature in the greenhouse is generally high, ammonium bicarbonate is more likely to decompose into ammonia and volatilize.
　　 Â
Ammonium chloride: The nitrogen content is about 25 %, the hygroscopicity is small, and it is stable at normal temperature. It is a physiological acid fertilizer. After being applied to the soil, the ammonium ions of the nutrient components can all be absorbed. Chloride ions in the soil ( ci -) the number may be accumulated, it is possible to constitute a poison for the crop. Rice, sorghum, millet, cotton, hemp, sugar beet, spinach and other chlorine-tolerant crops are strong and can be applied as needed. Barley, wheat, corn, soybeans, peas, beans, peanuts, radish, tomato, cucumber and other chlorine-resistant medium, administration may be constant. Sweet potato, flue-cured tobacco, lettuce, Chinese cabbage, apples, etc. have weak chlorine resistance, and are chlorine-free crops. It is not suitable to apply ammonium chloride.
　　 Â
Ammonium sulphate: The nitrogen content is about 21 %, the hygroscopicity is small, and it is stable at normal temperature, but it is not suitable for long-term application. Because the fertilizer is a physiological acid fertilizer, long-term application in acidic soil will further increase the acidity of the soil and destroy the soil structure. After application in alkaline soil, the ammonium ions in the ammonium sulfate are absorbed, and the sulfate ions remain in the soil and act on the calcium to make the soil compacted.
　　 Â
Ammonium nitrate: The nitrogen content is about 34 %, and the fertilizer effect is large. After being applied to the soil, the ammonium ion and the nitrate ion can be all absorbed, and there is no adverse effect on the soil, and it is a physiologically neutral quick-acting nitrogen fertilizer. Because ammonium nitrate can dissociate nitrate ions, it is easily leached into the deep layers of the soil in the paddy field, causing denitrification and loss of nitrogen. Therefore, it should not be applied to rice fields. The application of nitrate nitrogen fertilizer in dry land should not be carried out in heavy rain or After pouring large water. In addition, green leafy vegetables should not be applied to ammonium nitrate. Such as cabbage, Chinese cabbage, leeks, celery, spinach, etc., these vegetables have a short growth period and easily absorb nitrate nitrogen. Application of ammonium nitrate, nitrate ions are mostly absorbed by green leafy vegetables, for dishes, the short-term preservation, perishable. For people, if they eat these vegetables with high nitrates for a long time, they will cause cumulative poisoning.
　　 Â
Urea: The nitrogen content is about 45 %. It is the fertilizer with the highest nitrogen content in solid nitrogen fertilizer. It is stable in nature, less hygroscopic and soluble in water. It is a kind of high quality neutral nitrogen fertilizer. Higher urea nutrient content, applicable to all types of soil and crops. Urea is applied to the soil and can only be absorbed and utilized by the crops after being converted into ammonium carbonate. Therefore, the fertilizer is slower but more durable. In addition, the application should be applied deep in the soil, and the application should not immediately flood the water to prevent the urea from drenching into the deep layer and reducing the fertilizer efficiency.
