ProtoHumiX for potato.
Documented potato trials showed yield increases from 10.5% to 44% and additional profit from €755 to €18,095/ha, depending on variety, season, and program.
The potato grower problem
- • Tuber size, count and storage quality are highly sensitive to soil structure and humus content.
- • Continuous potato rotations degrade organic matter and weaken root development.
- • Mineral fertilizer alone does not restore soil buffering, leading to year-on-year yield plateaus.
- • Drought windows during tuber bulking can wipe out a full season of margin.
What ProtoHumiX changes
- • Improves soil vitality.
- • Optimizes water retention capacity.
- • Stabilizes pH and improves soil buffering capacity.
- • Improves nutrient availability.
- • Compatible with other treatments or fertilizers.
