The document discusses the benefits of using EDTA (ethylene diamine tetra acetic acid) as a chelate for soil and foliar applications of micronutrients. It explains that EDTA promotes nutrient transport in plants, avoids metal precipitation in soil and hard water, and can be mixed with most pesticides. It then compares the effectiveness and costs of using sulphate vs EDTA chelated micronutrients. Finally, it provides details on MetaClaw, Satyajit Chemicals' line of EDTA chelated micronutrients including calcium, copper, iron, magnesium, manganese and zinc.
