Ferroussulphate hepta for fertilizer:
1. With the application of ferrous sulphate fertilizer, the plant can not only supplement the iron in the plant, but also promote its absorption of nitrogen and phosphorus. Because ferrous sulfate has a strong reducing ability, it can also be greatly adjusted The redox process in plants promotes the absorption of various elements. The role of ferrous sulfate fertilizer2. The application of ferrous sulphate-based fertilizer and seed fertilizer can accelerate the decomposition of organic matter in the soil and prevent the occurrence of iron deficiency malnutrition in plants. For example, many flowers cause yellow leaf disease due to iron deficiency. With organic fertilizer, its effect is better.
3. The ferrous sulphate is formulated into a solution plant and applied on the leaf surface (usually formulated with lime), which can also prevent many flies from invading flowers and crops and diseases, such as rice fever, chlorosis, and early leaf withering , Cotton anthracnose, corner spot, plant death, etc.
4. The compound fertilizer made of 10% ammonium sulfate, 40% ferrous sulfate and 50% grass ash can prevent many crops from increasing damage while increasing the yield of corn and rice by 14.9% ~ 37.1%. In addition, ferrous sulfate solution Seeds impregnated with barley and wheat can prevent various hazards such as smut and stripe disease.
5. Because of the acidic nature of ferrous sulfate, ferrous sulfate has the effect of improving the acid-acid balance of the soil, so that the ferrous iron in its highly alkaline soil is converted into trivalent iron in the soil for a long time, reducing its alkalinity , Especially for calcareous soils.
Ferrous sulfate is widely used as an iron fertilizer, but it also has some unsuitable applications. For example, if the soil itself is acidic soil, if the plant needs iron to be ferric sulfate, it needs to be mixed with an alkaline agent when it is applied. (For example, lime) is added to avoid overacid of the soil and affect the plant growth environment. Secondly, it should not be applied together with calcium, magnesium, manganese, copper and other elements that have an antagonistic effect on iron, which will weaken or even make the iron fertilizer ineffective.
