1. Ammonium nitrogen fertilizer: including ammonium bicarbonate, ammonium sulfate, ammonium chloride, ammonia water and liquid ammonia. The advantage of this kind of nitrogen fertilizer is easy to be absorbed by the soil, but there are also some disadvantages. For example, it is easy to oxidize to nitrates and lose its original effect. At the same time, the high concentration of magnesium, potassium, calcium and other elements will be inhibited. And it is easy to volatilize in alkaline soil.
2. Nitrate nitrogen fertilizer: including sodium nitrate, calcium nitrate, ammonium nitrate, etc. This kind of nitrogen fertilizer is more soluble in water, but it is not easy to preserve in the soil, and it is easy to become gas volatilization. So when you use it, you need to water it to accelerate absorption.
3. Ammonium nitrate nitrogen fertilizer: mainly ammonium nitrate and its related compounds.
4. Amide nitrogen fertilizer: commonly known as urea, it has a high nitrogen content, but it is not suitable for all crops. Nitrogen tends to cause plants to grow in vain, delaying flowering and fruiting.
Nitrogen fertilizer can promote the growth of plants. Nitrogen deficiency often leads to short plants, thin branches, less roots, and yellow leaves without luster. And nitrogen fertilizer is excessive can make its growth too exuberant, have obstacle effect to its blossom and bearing, can affect its yield to a few crops..
