Application Guidance
Calculate additions using this product's 20% iron analysis and the requirements of your nutrient formulation. Do not substitute equal product weights for 30% iron monohydrate. Follow product-specific directions for application and handling rather than a universal rate.
Not for pesticidal or medicinal use. This material supplies iron and sulfur, not a complete fertilizer program.
