Supporting plant & soil performance
BorreGRO HA-1 acts in the root zone by stimulating key physiological processes that drive nutrient availability and plant development.
Root activity and development
- Activates plasma membrane H+-ATPase, promoting rhizosphere acidification
- Enhances root architecture, including lateral root formation and increased root surface area
- Supports early-stage root establishment and efficient soil exploration
Soil functionality:
- Improves soil structure and aggregation
- Stimulates beneficial microbial activity
- Increases Cation Exchange Capacity (CEC), helping retain nutrients in the root zone
Plant performance under stress:
- Supports plant tolerance to abiotic stresses such as drought and salinity
- Contributes to more stable crop performance under variable growing condition
BorreGRO HA-1 improves potato phosphorus uptake
A field study conducted on potato crops in Magic Valley, Idaho, USA, demonstrated improved phosphorus uptake when BorreGRO HA-1 was applied alongside fertilizer.
Petiole analysis throughout the growing season showed consistently higher phosphorus levels in plants treated with BorreGRO HA-1 compared to fertilizer alone, indicating improved nutrient availability and nutrient use efficiency. In addition to improved phosphorus uptake, treatment with BorreGRO HA-1 resulted in a larger percentage of the crop being classified as higher quality or larger size.
Key takeaways
- Improved nutrient use efficiency throughout the growing season
- Consistently higher phosphorus levels measured in potato petioles
- Enhanced phosphorus availability in the root zone
- Increased proportion of higher quality and larger potatoes

BorreGRO HA-1 demonstrates the ability to complex zinc
Demonstrations conducted in our laboratory confirm the ability of BorreGRO HA-1 to complex zinc and maintain stable liquid formulations. Zinc is an essential micronutrient widely used in starter fertilizers, and in its complexed form can contribute to improved nutrient use efficiency.
The concentrated active humic content in BorreGRO HA-1 provides strong complexing capacity for metal salts. Depending on the zinc source, approximately 15–20 grams of zinc can be incorporated into a stable liquid solution while maintaining formulation stability.
Key takeaways:
- BorreGRO HA-1 demonstrates the ability to complex zinc
- Over 15g of zinc/100g LS is shown to consistently be held in a stable formulation
- In their complexed form, nutrients are available for uptake by the developing root and/or foliar tissue of the plant

BorreGRO HA-1 offers superior formulation versatility
BorreGRO HA-1 improves formulation flexibility by enabling the incorporation of humic substances into low-pH fertilizer systems where conventional humates typically precipitate.
Compatible with fertilizers such as 10-34-0 and 28-0-0-9, BorreGRO HA-1 helps formulators create stable, clean fertilizer solutions while maintaining high humic content. This provides greater flexibility when developing liquid fertilizer formulations for modern crop nutrition programs.
As demonstrated below, conventional humic acids precipitate in low-pH fertilizers, while BorreGRO HA-1 remains stable and homogeneous. This helps reduce the risk of filter plugging and nozzle blockage during application.
Key takeaways
- Compatible with low-pH fertilizer systems
- Superior solubility compared to conventional humates
- Stable and homogeneous liquid formulations
- Helps reduce filter plugging and nozzle blockage
- Greater flexibility for liquid fertilizer formulators
