What are nitrogen fertilizers?

1. What are nitrogen fertilizers?

1. Ammonium nitrogen fertilizer: There are many types of ammonium nitrogen fertilizers, including ammonium sulfate, ammonia water, ammonium bicarbonate, liquid ammonia, ammonium chloride, etc. However, they have many similarities, such as being easily adsorbed by soil colloids and turning into nitrates after oxidation. This fertilizer is more likely to volatilize in an alkaline environment. If plants or crops absorb excessive amounts, 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 calcium nitrate, sodium nitrate, ammonium nitrate, etc. Its commonality is that it is more easily soluble in water and has no inhibitory effect on crops' absorption of potassium, magnesium, calcium, etc. 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 and 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 to promote growth, the most commonly used fertilizer is urea fertilizer, which has a better effect.

2. What is the role of nitrogen fertilizer?

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