ProtoHumiX for potato.
Documented potato trials show yield uplift from 10.5% to 44% and additional profit from 755 to 18,095 EUR/ha, depending on variety, season and program.
The potato grower problem
- • Tuber size, count and storage quality are very sensitive to soil structure and humus content.
- • Continuous potato cropping depletes organic matter and weakens root systems.
- • Mineral fertilizer alone doesn't restore soil buffering, leading to year-on-year yield stagnation.
- • Dry spells during tuber bulking can wipe out a season's margin.
What ProtoHumiX changes
- • Improves soil vitality.
- • Optimizes water-holding capacity.
- • Stabilizes pH and improves soil buffering.
- • Improves nutrient availability.
- • Compatible with other treatments and fertilizers.
