3. Function of Kieserite
Kieserite for agriculture
Sulfur and magnesium can provide rich nutrients for crops that it contributes to crop growth and increase the output, it also helps to loosen the soil and improve soil quality.
The symptoms of lacking of "sulfur"and"magnesium":
1)it lead to exhaustion and death if it's serious lacked;
2)The leaves became smaller and its edge will became dry shrinkage.
3)Susceptible to bacterial infections in premature defoliation.
