Ferrous Sulphate Heptahydrate

Crops are treated with ferrous sulphate heptahydrate (copperas). Copperas is a moist green salt with the consistency of wet snow. It is also known as iron vitriol or green vitriol. It dissolves easily in water and is sprayed to iron-deficient crops where it is promptly absorbed by the plants.

Molecular Formulae-

Alternative Names- Iron Vitriol, Green Vitriol

BENEFITS AND APPLICATIONS-

• It provides energy for the plant to grow more quickly.
• It aids in the resistance of plants to disease and insects.
• It helps in the reduction of iron deficiency, as iron deficit plant produces chlorosis, which causes leaves to yellow and reduces their capacity to generate chlorophyll.
• It is also used as a lawn conditioner and moss killer.

HOW IT WORKS-

• It works as an iron-rich fertilizer that can be easily absorbed by the plant.
• It works by neutralising the soil’s pH with its acidic pH.

TIME OF APPLICATION-

• It can be used throughout the year.

RECOMMENDED USAGE-

• It is recommended to use at a concentration of 20% pure ferrous sulphate in fertilizer.
• For soil application, 25-30 Kg/acre.

HOW TO USE-

• Mix it with compost and dig it into the soil to create a store that can last for years. 
• For flowers, shrubs, and trees, only 20% dried ferrous sulphate is advised, with a dry application of 1/2 cup to 1 cup per 100 square feet.
