Nitrogen fertilizers mainly include three types: ammonium nitrogen fertilizer, nitrate nitrogen fertilizer and amide nitrogen fertilizer. Among them, ammonium nitrogen fertilizer is more easily adsorbed by soil colloids and is more volatile in an alkaline environment. Nitrate nitrogen fertilizers are more soluble in water. Amide nitrogen fertilizer is urea, which is the fertilizer with the highest nitrogen content and is commonly used in daily life. Nitrogen fertilizer can promote photosynthesis of plants, which is more beneficial to growth.

1. What are nitrogen fertilizers?

1. Ammonium nitrogen fertilizers: Ammonium nitrogen fertilizers include many types, including ammonium sulfate, ammonia water, ammonium bicarbonate, liquid ammonia, ammonium chloride, etc. However, they have many similarities. For example, they are easily adsorbed by soil colloids and turn into nitrates after oxidation. This fertilizer is more volatile in an alkaline environment. If plants or crops absorb too much, it will have an inhibitory effect, and if the concentration is high, it will easily cause toxicity.

2. Nitrate nitrogen fertilizer: Nitrate nitrogen fertilizer includes nitric acid Calcium, sodium nitrate, ammonium nitrate, etc. What it has in common is that it is more easily soluble in water and has no inhibitory effect on the absorption of potassium, magnesium, calcium, etc. by crops. It is mainly used in alkaline fertilizers.

3. Amide nitrogen fertilizer: Amide nitrogen fertilizer is what we usually call urea fertilizer. It contains 46.7% nitrogen fertilizer. It is the fertilizer with the highest nitrogen content among solid nitrogen. Therefore, if you want to replenish the required nitrogen fertilizer as soon as possible and promote growth, the most commonly used fertilizer is urea fertilizer, which has better effects.

2. What is the role of nitrogen fertilizer?

Nitrogen is one of the three major elements for plant growth and is indispensable. It is also the main component of protein in crops. If it is a crop, a serious lack of nitrogen fertilizer for the plant will be life-threatening. In addition, if there is a lack of nitrogen fertilizer, plants may become thin, leaves may turn yellow, and growth may slow down. An appropriate amount of nitrogen fertilizer can help plants carry out photosynthesis and is beneficial to growth.
