1.Improve nutrient uptake through the leaves and roots
2.Improve the effectiveness of pesticides
3.With lower molecular weight and high biological activity,improve nutrient uptake of plant
4.Increases yield and improves the quality of plants
The specific use methods are as follows:
1. It can be used as base fertilizer. When potassium sulfate is used as base fertilizer in the dry field, it is necessary to deeply cover the soil to reduce the crystal fixation of potassium, facilitate the absorption of crop roots and improve the utilization rate.
2. As topdressing. As the mobility of potassium in the soil is small, it should be applied to the soil layer with dense root system in order to promote the absorption.
3. It can be used as seed fertilizer and root top dressing. The amount of seed fertilizer used per mu is 1.5-2.5kg, which can also be made into 2% - 3% solution and used as external topdressing.
