Product Description

1. The role of potassium sulfate fertilizer:

1. Potassium sulfate fertilizer is suitable for all kinds of soil, especially in neutral and alkaline soil. In some sandy loam or red soil, the application of potassium sulfate fertilizer can supplement the potassium and sulfur needed for crop growth and improve soil fertility. The potassium in the potassium sulfate fertilizer is generally not adsorbed by the soil, and the utilization rate is high.

2. Potassium sulfate fertilizer is applied to various crops, which can quickly supplement the potassium element required for crop growth. It is especially suitable for sweet potatoes, potatoes, watermelons, tobacco, and fruits and vegetables in greenhouses. It can not only improve the growth of crops, but also improve the taste, which is the effect that potassium chloride cannot achieve.

On garlic, the use of potassium sulfate can also play a role in improving quality. Because garlic loves sulfur, using potassium sulfate can enhance the flavor of garlic and promote bulb growth.

3. After potassium sulfate fertilizer is used, it is beneficial to improve the stress resistance and cold resistance of crops.
