Misunderstandings in the use of urea and their correction methods

Urea is a common agricultural fertilizer, which is widely used in the cultivation of various crops. However, in the process of using it, many farmers have some misunderstandings, which affect the effect of urea. This article will introduce the common misunderstandings of urea and how to correct them in detail to help farmers improve the efficiency of fertilizer use.

Misunderstanding 1: Too much application

Many farmers believe that the more urea they apply, the better their crops will grow. But in fact, excessive urea will not only fail to increase crop yields, but will lead to soil salinization and affect the health of crop roots.

Correction method: According to the soil test results and the needs of crops, apply urea reasonably. Generally, the application amount per mu of land should be controlled between 10-20 kg.

Misunderstanding 2: Spreading directly on the surface

If urea is directly spread on the ground surface, the nitrogen will easily volatilize, the fertilizer effect will be difficult to sustain, and huge waste will occur.

Correction method: Urea should be mixed with the soil and applied 5-10 cm deep into the soil layer to reduce nitrogen volatilization and improve fertilizer efficiency.

Misunderstanding 3: Ignoring the use of other fertilizers

Some farmers only apply urea alone and ignore the supply of other nutrients, resulting in unbalanced crop growth.

Correction method: Urea should be used in combination with other fertilizers such as phosphorus fertilizer and potassium fertilizer to meet the crop's needs for various nutrients.

Myth 4: Fertilizing in hot weather

When urea is applied in hot weather, nitrogen is easy to volatilize and the fertilizer efficiency is reduced. High temperature may also damage crops.

Correction method: Apply urea in the morning or evening when the temperature is lower to reduce the risk of nitrogen volatilization.

By understanding and correcting these usage misconceptions, farmers can apply urea more scientifically, increase crop yields, protect soil health, and achieve sustainable agricultural development.
