Hydra-Hume is a fertilizer efficiency tool designed to help you get more from the valuable fertilizer you apply.  It increases fertilizer uptake, and helps retain nitrogen and phosphorus in the soil for greater utilization and less leaching. Hydra-Hume helps prevent nutrient tie-up by improving nutrient availability, while improving soil structure and aggregation to allow for better water movement. Hydra-Hume is available in dry granular or liquid formulations.
