Choosing an Iron Source

Compare iron sulfate products by nutrient concentration, physical form and intended application. Heptahydrate and monohydrate are different forms of ferrous sulfate; calculate additions from the analysis of the product you are using rather than substituting equal product weights.

Application and Handling

Follow the product label for application and handling instructions. Base nutrient additions on your formulation and crop requirements rather than a universal application rate. Review the storage and handling information before use. This untreated material may cake over time.
