It is used for nutrient solutions that support plant growth, trace element fertilizers for hydroponics, soil conditioners, feed minerals, and wastewater treatment agents.
◎About the Use of Fertilizers Iron (Fe), a trace element essential for plant growth, plays a central role in chlorophyll production and energy generation. A deficiency of iron adversely affects the life activities of plants, leading to serious issues such as leaf chlorosis and stunted growth. Among the solutions, ferrous sulfate is used as a reliable trace element fertilizer. Ferrous sulfate is water-soluble and is widely utilized as an essential trace element fertilizer in hydroponics. It is particularly effective in addressing iron deficiency in sandy and alkaline soils. In the agricultural sector, it is recognized as a fast-acting iron fertilizer. As for usage methods, spraying ferrous sulfate or applying it as a foliar spray are direct and effective ways to supply iron. Ferrous sulfate supports plant growth and health while efficiently promoting the uptake of iron from the soil. If the goal is to enhance productivity and quality, the use of ferrous sulfate is ideal. ◎About Industrial Applications Heptahydrate has many uses in wastewater treatment applications. It can be used as a coagulant, reducing agent, and precipitant to remove sulfides and phosphorus from wastewater.
