TOP UP is a 100% EDTA chelated micronutrients. TOP UP is used directly with the seed at planting time or on the plant foliage. Top UP products have a neutral pH and are low in both salt index and impurities. Placement with the seed allows the EDTA chelated micronutrients along with the available phosphorus and potassium to be taken up at the critical early stages of growth to maximize yield potential. This rapid uptake at critical growth stages promotes plant health and increased yield potential. It can be applied for critical early stages of growth.
