HUMAGRA? NPK 10-0-3 + HA Liquid is an organomineral fertilizer which contains humic acids, nitrogen, and potassium. Beside providing these macronutrients to supplement plant nutrition, the product acts as a soil conditioner and plant growth stimulant. It is a permanent humic substance, which is relatively slowly decomposed by microorganisms of the soil. HUMAGRA? NPK 10-0-3 + HA Liquid can be used alone or mixed with most fertilizers.

HUMAGRA? NPK 10-0-3 + HA Liquid is obtained through alkaline extraction from German Leonardite (highly oxidized lignite), with addition of soluble nitrogen sources. Leonardite arises from the chemical and biological humification of plants and other organic matter, by biological activity and geological processes. This formulation provides a very high content of humic and fulvic acids and a high quantity of nitrogen and potassium.   

HUMAGRA? NPK 10-0-3 + HA Liquid provides positive fertilizing and soil-conditioning effects, specially in sandy and heavy soils. The product can be applied to all agricultural and horticultural crops, either directly to the soil or as a foliar spray.
