Humic Acids Application

This humic acid powder can be applied dry, but it is more commonly mixed with water in a watering can, sprayer, or irrigation system. Although the application rate is very low, it is optimal, so applying more is not better.

Whenever it is used in water, thoroughly pre-mix the desired amount of powder with water in a separate container in order to dissolve the powder before adding it to the final liquid tank.

Soil - For direct soil applications, apply 20 to 100 ml per 1000 sq ft.  For the best results, apply at planting or prior to germination.  Applications may be made every 4-6 weeks during the growing season.

Foliar - Apply only 2-4 ml per 1000 sq ft.  The spray concentration should range between 1:650 (1.5 ml per litre) to 1:13000 (1.5 ml per 20 litres). Apparently 1:6500 (1.5 ml per 10 litres) is best. This stuff goes a long way.

Compost Tea - Add 13 ml of humic acid into your 5 gallon brewer. No more.
