Specifications:

WORKS IN ALKALINE SOILS WHERE EDTA FAILS – DTPA chelation stays stable up to pH 7.5, solving iron lockout in high-pH soils and hard water conditions; the go-to choice when standard iron chelates stop working; delivers 3-5x better absorption than iron sulfate in challenging alkaline environments
11% CHELATED IRON FOR SUPERIOR ALKALINE PERFORMANCE – DTPA technology keeps iron plant-available in neutral to moderately alkaline conditions (pH 4.0-7.5); bridges the gap between economical EDTA (max pH 6.5) and premium EDDHA (pH 9.0) at a practical price point
TURNS YELLOW LEAVES GREEN IN 7-10 DAYS – Corrects interveinal chlorosis (yellow tissue with green veins) on new growth even in tough alkaline conditions; foliar spray shows visible greening in one to two weeks; soil applications provide sustained correction lasting four to six weeks
100% WATER SOLUBLE FOR ANY APPLICATION – Dissolves completely with no residue for foliar spray, soil drench, fertigation, and hydroponic systems; apply 1-2 tsp/gallon foliar or 1-2 tbsp/gallon soil drench; ideal for hard water and high-pH irrigation systems
