Characteristics and Application of Ammonium Sulfate

Ammonium sulfate is an important nitrogen fertilizer that dissolves quickly and is easily absorbed by plants. Due to its suitable nitrogen-phosphorus ratio, ammonium sulfate is widely used in agricultural production, especially in fertilization of different soil types, where it can play a unique role.

The proportion of ammonium sulfate used in different soil types

According to the characteristics of the soil, the proportion of ammonium sulfate needs to be adjusted. The following is an analysis of several major soil types:

1. Sandy soil

In sandy soil, due to the large soil particles and poor water and nutrient retention capacity, it is necessary to increase the application rate of ammonium sulfate. The recommended application rate is 5-8 kg per mu, which can effectively supplement soil nutrients and improve crop resistance.

2. Loam

Loam has good air permeability and water retention, and the application amount of ammonium sulfate is relatively moderate. It is recommended to apply 4-6 kg per mu, which can meet the nitrogen supply required for crop growth.

3. Clay

Clay has a strong water and nutrient holding capacity, but due to poor air permeability, it is easy to lose nutrients. When using ammonium sulfate in clay, the recommended application rate is 3-5 kg ​​per mu to avoid soil acidification and nutrient waste.

Expert advice

During the application of ammonium sulfate, it is recommended to conduct regular soil testing to determine soil nutrients and pH to ensure scientific fertilization. In addition, measures such as crop rotation and intercropping can effectively reduce the risk of nutrient loss and acidification in the soil and achieve sustainable agricultural development.

Summarize

The proportion of ammonium sulfate used in different soils varies depending on the soil type. Through reasonable fertilization, not only can the yield and quality of crops be improved, but the environment can also be effectively protected to achieve the goal of green agriculture.
