IRON SULFATE - FERROUS SULFATE  

Dried Ferrous Sulfate (FeSO4·7H2O) is free-flowing, has consistent iron, sulphur, water, and oxygen contents, and dissolves rapidly in solution. 

In agricultural, lawn and garden, and turf management, Ferrous Sulfate may be used to correct iron chlorosis or deficiencies in plants and soils. Due to its sulphur content, it will also help to reduce alkalinity.   

In Organics, Iron Sulfate may be used when soil and plant deficiencies are documented by visual symptoms, testing soil and/or plant tissue, or when the need for a preventative application can be documented.

​Application rates will vary depending on the nutrient level in your soil. Application amounts should be based on soil or leaf tissue analysis results.    

• In the garden:  up to 10-30 grams per 1m² (10ft²). Mix with water and apply to the soil surface to correct deficiencies

• Lawns: 60-90 grams per 1000 sq ft   (dissolve in 3-5 gallons of water for a foliar application)
