Application Rates & Guidelines
Soil Application
Highassay’s humic acid solution for soil application allows for flexible dosage adjustments based on crop type and growth stage. To ensure optimal results, the product can be applied in multiple doses throughout the growing season.
Foliar Application
For Highassay’s liquid humic acid foliar spray, we recommend applying once every two weeks. Spray during the early morning or late evening when there is little to no wind, focusing on the undersides of the leaves; this facilitates faster absorption, promotes plant health, and increases yields.
