Nitrogen fertilizer is a fertilizer based on nitrogen. There are many types, but their functions are basically the same. It can provide essential nutrients for plant growth, so it is beneficial to most plants. However, excessive application of nitrogen fertilizer can also inhibit flowering and fruiting, so rational use is particularly critical.

1. Common types

1. Ammonium nitrogen fertilizer: including ammonium bicarbonate, ammonium sulfate, ammonium chloride, ammonia and liquid ammonia. The advantage of this type of nitrogen fertilizer is that it is easily absorbed by the soil, but it also has some disadvantages. For example, it is easily oxidized into nitrate and loses its original efficacy. At the same time, high concentrations can also be harmful to crops and inhibit the absorption of magnesium, potassium, calcium and other elements. And it is easily volatile in alkaline soil.

 

2. Nitrate nitrogen fertilizer: including sodium nitrate, Calcium nitrate and ammonium nitrate, among others. This type of nitrogen fertilizer is more soluble in water, but is not easy to preserve in the soil and can easily become volatilized as gas. Therefore, water it when using it to speed up absorption.

3. Ammonium nitrate nitrogen fertilizer: mainly ammonium nitrate and its related compounds.

 

4. Amide nitrogen fertilizer: commonly known as urea, containing Nitrogen is high, but not suitable for all crops. Nitrogen can easily cause plants to grow leggy and delay flowering and fruiting periods.
