GREENHUM is an organic liquid fertilizer with high concentration of humic acids from leonardite. Humic acids improve cation-exchange capacity in the soil and increase the availability of nutrient elements for plants.
By foliar spraying, the product increases the permeability of cell membranes allowing a better absorption of nutrients; in mixture with common fertilizers, it enhances their properties.
We recommend applying GREENHUM in sandy soils, saline soils, with high pH or lack of organic matter.
