GS Plant Foods’ Liquid Humic Acid is easily assimilated by plants and some of its main functions include improving plant immunity, improving plant metabolism, improving plant root development, improving the supply of plant nutritional elements and increasing the formation of ferments.

Humic Acid promotes the increased accumulation of chlorophyll, sugar, amino acids and more and improves the efficiency of nitrogen utilization, allowing for reduced fertilizer rates. One of the primary actions of Humic Acid is to increase the plant’s ability to withstand the stresses of heat, drought, cold, disease, insect and other types of environmental or cultural pressures. Humic also increases general plant productivity, in terms of yield, as well as plant stem strength. Within the soil, humic stimulates soil microorganisms, promoting Humus.
