YARA SOLUBLE BORON

Image of YARA SOLUBLE BORON
21% Soluble Boron is a soluble powder formulation that gives the potential for a higher nutrient concentration than a liquid, meaning lower application rates, less product to handle and store, less packs to recycle, whilst also making it easy to mix the product in the spray tank.

A broad tankmixability makes it easy to co-apply the products with agrochemicals, saving both time and money. Just as important, free access to Tankmix information online or via smart phones makes it quick and easy to check whether products can be co-applied.
