Nitrate nitrogen and ammonium nitrogen BY:Cherry

Potassium nitrate is a commonly used fertilizer in agriculture.

Nitrate nitrogen and ammonium nitrogen are two forms of nitrogen that are essential for plant growth. They play an important role in the growth process of plants, but their properties, functions, and how they are used in agricultural production are different.

What are the effects of potassium nitrate?

1. Definition and difference between nitrate nitrogen and ammonium nitrogen

Nitrate nitrogen, also known as nitrate nitrogen, refers to nitrogen in the form of nitrate that can be absorbed by plants. It mainly comes from the decomposition of nitrate minerals and organic matter in the soil. Nitrate nitrogen has strong mobility in the soil and is easily absorbed by plants, but it is also easy to lose.

Ammonium nitrogen, also known as amino nitrogen, refers to nitrogen in the form of amino that can be absorbed by plants. It mainly comes from amino acids and ammonia nitrogen in the soil. Ammonium nitrogen has poor mobility in the soil, but it is not easy to lose.

2. The nature and role of nitrate nitrogen

Nitrate nitrogen is a fast-acting form of nitrogen that can quickly meet the needs of plant growth. Nitrate nitrogen is easily absorbed by plants in the soil, which has a good effect on increasing the early growth rate and leaf area of plants. In addition, nitrate nitrogen can also promote the absorption of other mineral elements by plants.

3. The nature and role of ammonium nitrogen

Ammonium nitrogen is a slow-acting form of nitrogen that has a lasting effect on plant growth. Ammonium nitrogen is not easily lost in the soil, which can ensure a long-term and stable nitrogen supply for plants. In addition, ammonium nitrogen can also improve plant resistance and promote plant growth.

4. The role of nitrate nitrogen and ammonium nitrogen in agricultural production

In agricultural production, the application of nitrate nitrogen and ammonium nitrogen has different focuses. Nitrate nitrogen is suitable for the early stage of crop growth, which can quickly increase the growth rate of crops and lay the foundation for high yields. Ammonium nitrogen is suitable for the middle and late stages of crop growth, which can ensure a stable nitrogen supply for crops and improve crop quality.

5. How to reasonably apply nitrate nitrogen and ammonium nitrogen

To achieve the reasonable application of nitrate nitrogen and ammonium nitrogen, we must first understand the nitrogen demand characteristics of different crops. For crops with high nitrogen requirements, such as rice, wheat, etc., the application of nitrate nitrogen and ammonium nitrogen can be appropriately increased. Secondly, we need to master the timing of applying nitrate nitrogen and ammonium nitrogen. Generally, nitrate nitrogen is applied in the early stage of crop growth, and ammonium nitrogen is applied in the middle and late stages of growth. Finally, we need to pay attention to the application ratio of nitrate nitrogen and ammonium nitrogen to avoid excessive application leading to environmental pollution.

In short, nitrate nitrogen and ammonium nitrogen play an important role in the growth process of plants.
