Ferrous sulfate plays an important role in restoring soil vitality. Ferrous sulfate is especially suitable for alkaline soil, compacted soil, salt-damaged soil, soil contaminated by heavy metals and pesticides. The main advantages of ferrous sulfate in soil repair are:
1. Ferrous sulfate adjusts soil pH.
2. Ferrous sulfate can adsorb and settle heavy metals and reduce the toxicity of heavy metal elements to plants;
3. Ferrous sulfate can effectively improve soil compaction and prevent the invasion of plant soil-borne diseases;
4. Ferrous sulfate improves the soil structure and increases the iron element in the soil, improves the utilization rate of soil nutrients, enhances the moisture and fertilizer retention capacity of the soil, maintains effectiveness for a long time, increases crop yield, and has obvious application effects.
5. Ferrous sulfate serves as a reducing agent. After being injected into the soil, it converts pollutants in the soil or groundwater into non-toxic or relatively less toxic substances through oxidation or reduction.
Ferrous sulfate soil remediation method:
Contaminated soil and ferrous sulfate must be thoroughly mixed to achieve their maximum effect. The dosage of ferrous sulfate required for soils with different degrees of pollution is also different. Before a large amount of mixing, a small soil test must be conducted to determine the dosage of ferrous sulfate. First, the soil should be plowed, and the ferrous sulfate agent should be spread based on the results of the small test. Then the ferrous sulfate and soil should be stirred and mixed. The mixing time should be as long as possible to ensure the uniformity of the ferrous sulfate agent and soil. , so that the ferrous sulfate agent and the contaminated soil are fully contacted, so that the maximum effect of ferrous sulfate can be exerted.
Application of ferrous sulfate on plants:
Ferrous sulfate plays a great role in the growth and development of plants. In addition to supplementing plant requirements, it can also promote the absorption of nitrogen and phosphorus fertilizers and prevent yellow leaves caused by iron deficiency in plants. Ferrous sulfate can The pH of the soil is quickly balanced. It is generally prepared freshly when used and sprayed on the leaves or irrigated roots.
1. Supplement iron element
Plants need iron during the growth process. In addition to supplementing the needs of plants, Sega ferrous sulfate fertilizer can also promote the absorption of nitrogen and phosphorus fertilizers, increase the absorption of elements in plants, and make plants grow better.
2. Treatment of iron deficiency yellow leaf disease
Iron deficiency will cause yellow leaf disease in plants, and the role of ferrous sulfate is to prevent the yellow leaf phenomenon caused by iron deficiency malnutrition in plants.
