Green Prairie Ranch Humic Acid is an environmentally safe, organic matter that can be used on crops (vegetable and non-vegetable), turf and grasses, trees, flowers, vines and ornamentals. It can be applied to all soil types and pH ranges, to all transplant solutions, dips, and to all watering solutions.

Humic acid's organic composition supports optimum plant growth, increases plant quality and production and improves and replenishes soils depleted of organic matter. It can be mixed with fertilizer, nutrient solutions and/or chemicals.

GPR Humic Acid is extracted from leonardite, a naturally occurring mineral deposit formed in the earth over millions of years by the chemical and biological decomposition of prehistoric plant and animal matter. It's nature's liquid compost. Shake well before using. May stain, keep off unwanted surfaces.
