Keal is a highly concentrated liquid fulvic acid derived from humalite, a highly concentrated source of humic and fulvic acid found exclusively in Alberta, Canada. This high CEC, low molecular weight fulvic acid helps to build root systems, grow biomass, enhance nutrient uptake and availability, contributing to higher crop yield and overall quality.

Keal is a powerful chelating agent for enhancement of both soil and foliar nutrient applications. It is compatible with virtually any liquid crop input and aids in uptake and penetration through root and leaf membranes.

Sizes available: 265 gal (1000L) and 5 gal (18.9L)
