II. How to use magnesium sulfate fertilizer:

It can be used as base fertilizer or top dressing. Generally, about 12.5-15kg of magnesium sulfate

should be applied per mu. Usually, the effect of topdressing the roots to correct the symptoms of

magnesium deficiency is more significant, but the disadvantage is that the fertilizer effect is not

long-lasting, and continuous spraying is required to ensure that the crops are supplemented with

sufficient magnesium. For example, when magnesium deficiency occurs in rice and corn, 2%

magnesium sulfate solution can be sprayed 3-5 times every 14 days, which is faster than applying

magnesium sulfate fertilizer to soil.

It is the best supplement for magnesium-deficient crops and soil. When the crops or soil are

magnesium-deficient, magnesium sulphate fertilizer can be selected as the best magnesium supplement

fertilizer, because magnesium sulfate is easily soluble in water, easy to absorb, and does not damage

the soil pH value characteristics. Not only can it be used as a magnesium supplement additive for

compound fertilizers, but it can also be mixed with other fertilizers or used alone to make compound

fertilizers supplemented with multiple elements. It can be used as base fertilizer, top dressing, or as

foliar spray fertilizer, but the effect of foliar spray may be better.
