Liquid humic acids
Foliar • Fertigation • Organic Farming
Stemma Hum is an organic liquid fertilizer with high content 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.

Stemma Hum is ideal in sandy soils, saline soils, with high pH or lack of organic matter.
