Humic Acid

HUMIC ACIDS are complex organic molecules formed by the breakdown of organic matter in the soil

They are not considered to be fertilizers per se, but soil enhancers and improvers.

HUMIC ACID biologically stimulates plant growth, chemically changes the fixation properties of soil and physically modifies the soil.

DIRECTIONS

(Shake Well Before Using)

May be applied to soils in irrigation or sprinkler systems, or applied as a foliar spray.

FOLIAR SPRAY: Apply 1 to 4 quarts per acre (2‑9 liters/HA 450 to 900 liters) in sufficient water.

For full coverage spray, use 1 to 4 quarts in 50 to 100 gallons of water or 1 oz per 1,000 sq.ft. in 10 to 20 gallons of water. Stir or shake before using, add to tank when half full.

Compatible over full range of tank mix pH. We recommend buffering your spray tank pH in the range of pH 5.5 by adding 2 to 7 Lbs. Grow More 20‑20‑20 per 100 gallons of water.

USE 50 MESH SCREENS: Check compatibility with pesticides or liquid fertilizer before full scale tank mix.

SOIL APPLICATION: By itself use 2 to 10 quarts per acre in ground application equipment or sprinkler irrigation runs. Maybe used in direct seeded crops. It may also be used in combination with starter or pop‑up fertilizers, 2 to 3 quarts per acre.

Grow More’s 12% HUMIC ACID is a concentrated liquid extract derived from Leonardite ore. Weight is 9

Lbs./gallon (d=1.08), equivalent to 1.08 Lbs. Humic Acid per gallon.

PESTICIDE COMPATIBILITY:

Grow More’s 12% Humic Acid is compatible with most insecticides, herbicides, miticides, fungicides and foliar fertilizers.

It may be incorporated into existing spray programs. Add Grow More’s 12% HUMIC ACID to the water prior to the

pesticides. Perform jar compatibility test prior to full‑scaled tank mixing when using previously untried combination.

FERTILIZER COMPATIBILITY:

Grow More’s 12% HUMIC ACID is compatible with 32 and 28% Nitrogen solution. Before adding to liquid fertilizer or

ammonium phosphate, dilute 1 part Grow More’s 12% HUMIC ACID with 1 to 2 parts water. Before using previously

untried combinations, perform jar compatibility test prior to full scale tank mixing.

FOLIAR APPLICATION:

For best absorption into plant, apply this product early morning or late evening. For aerial application, use at least 1

gallon of water for every pint of 12% HUMIC ACID applied to the crops.
