BorreGRO HA-1

BorreGRO® HA-1 is a modified humic acid that increases the uptake of soil-applied plant nutrient solutions, is fertilizer compatible and adds carbon content for soil microorganisms.

BorreGRO HA-1 is a specially formulated, modified potassium humate derived from leonardite. The product offers superior solubility in low pH solutions, which allows for the highest humic content in fertilizer formulations. Concentrated active humic content means more complexing capacity for metal salts, more carbon content for soil microbes and higher nutrient use efficiency in every fertilizer application.

Nutrient use efficiency

The addition of BorreGRO HA-1 to starter fertilizers can improve nutrient retention in the soil profile and gives healthier, higher-yielding plants.

Complexing capacity

BorreGRO HA-1 prevents phosphorus fixation and complexes metal salts.


The unique nature of BorreGRO HA-1 makes it the most versatile potassium humate available today.
