The symptoms of lacking of Sulfur and Magnesium:
1. It leads to exhaustion and death if it’s serious lacked.
2.The leaves become smaller and their edge will become dry shrinkage.

1. Magnesium sulfate is used as base fertilizer
Magnesium sulfate can be mixed with other fertilizers or organic fertilizers and applied in the soil before farmland. Generally, the amount of magnesium sulfate used for agricultural use is about 10kg per mu.
2. Magnesium sulfate is used as topdressing:
Magnesium sulfate topdressing should be applied early, and furrow application or flushing with water can be used. Generally, 10-13kg magnesium sulfate is suitable for each mu of land, and 250-500g magnesium sulfate can be applied to each fruit tree; after sufficient magnesium fertilizer is applied, it can be applied again after several crops, and it is not necessary to apply magnesium sulfate every season.
3. Magnesium sulfate is used for foliar spray:
Generally, the foliar spraying concentration of magnesium sulfate is 0.5% - 1.0% for fruit trees, 0.2% - 0.5% for vegetables, 0.3% - 0.8% for rice, cotton and corn, and the application amount of magnesium fertilizer solution is about 50-150 kg per mu.
