Brand: Miller Chemical
Microplex Chelated Micronutrients
Microplex from Miller Chemical is a water-soluble blend of eight micronutrients, with iron, manganese, zinc, copper, cobalt and part of the magnesium chelated with EDTA for maximum plant response. The microgranule formulation is easy to handle and dissolves readily in spray solutions and drip irrigation systems, delivering more than 17% total micronutrients.
Microplex is particularly suited to foliar application, inclusion in liquid feeds and hydroponic mixes, and soil application where micronutrient deficiency is diagnosed or suspected. It is compatible with phosphate-based fertilizers and can also be incorporated into dry NPK blends. Foliar feeding is intended to supplement, not replace, a regular fertility program.
