Soil improver in powder form, brown. It declares 50% w/w fulvic acids and 50% w/w total humic extracts, with 60.60% w/w total organic matter, 9.00% w/w total amino acids, 3.82% w/w total nitrogen and 12.00% w/w potassium oxide (K₂O). Humic and fulvic acids act on soil structure and on nutrient availability. It is applied at 250-500 g/100 L foliarly, at 2-6 kg/ha through fertigation, and as a soil treatment. Measured chloride: 5.62% w/w, the highest of those measured in the catalogue.
