Effect of magnesium sulfate fertilizer
1. Magnesium sulfate fertilizer can promote the absorption of other elements by plants. An important component of chlorophyll is magnesium, which is contained in chlorophyll a and chlorophyll B. Magnesium is an activator of many enzymes, which is closely related to carbohydrate metabolism and phosphorylation.
2. Magnesium can not only activate phosphofructokinase and phosphoglycerokinase, but also promote carbohydrate metabolism and plant respiration. It can also promote the synthesis of adenotriphosphate from adenodiphosphate.
3. Magnesium also plays an important role in the metabolism of fat and ammonia. It can also promote the absorption of ammonia, phosphorus, potassium and other elements by plants.
How to use magnesium sulfate fertilizer
1. Can be used as base fertilizer or topdressing
Generally, about 12.5-15kg magnesium sulfate should be applied per mu. Generally, the effect of applying fertilizer outside the root for magnesium deficiency is better, but the only drawback is that the fertilizer effect is not lasting and needs to be sprayed continuously. When magnesium deficiency occurs in rice and maize, 2% magnesium sulfate solution can be sprayed 3-5 times every 14 days, which is faster than soil fertilization.
2. The best supplement for magnesium deficient crops and soil
When crops or soil are short of magnesium, magnesium sulfate fertilizer can be selected as the best magnesium fertilizer, because magnesium sulfate is easy to absorb and does not damage the pH value of soil. It can not only be used as magnesium supplement additive for compound fertilizer, but also can be mixed with other fertilizers or used alone. It can be used as basal fertilizer, topdressing and foliar spraying, but the foliar spraying effect may be better.
