One real potato crop. Four DRIS stages.
Follow a potato crop from preplanting soil correction to a marketable harvest, every stage guided by DRIS.
The process
Four stages, one balanced season.
01
Preplanting
Soil analysis and custom soil correction: calcium and phosphate blends to fix deficiencies before planting.
02
Root development
Enhanced root development and soil aeration. Controlled early growth builds deep, healthy roots.
03
Tuber initiation
Early tuber initiation and uniform set: short, strong stolons with no weaning and consistent sizing.
04
Bulking & resilience
Nano-calcium reduces soil compaction and improves ridge aeration for uniform bulking and fast stress recovery.
Stage 01–02 · Foundation
A strong start under the surface.
We used DRIS to identify nutrient deficiencies and imbalances in the soil, then applied custom rectification blends, including available calcium and phosphate, to correct them. The planting fertiliser mix was tailored to the corrected balance and the crop's early needs.
Early vegetative growth stayed controlled, letting the crop focus on building deep, penetrating roots that improve nutrient uptake and aeration, and prepare the plant to withstand stress.




Stage 03–04 · Yield
Uniform tubers, consistent quality.
With the DRIS nutrient program, including precise foliar applications, tuber initiation began early, with short strong stolons and no weaning. That led to uniform tuber development: potatoes of consistent size and quality, significantly improving marketability and pack-out.
Custom soil blends improved structure throughout the season: better flocculation, aeration and water penetration, sustained right through bulking.
The DRIS method
How It Works
DRIS uses the Mulder's Chart to evaluate nutrient interactions against each other, not just levels or norms.
DRIS brings Liebig's Law of the Minimum into practice by identifying limiting and suppressing factors that restrict growth.
DRIS can calculate per kg per ha what recommendation is required to restore balance and production.
Nutrient plans are adjusted in real time using the DRIS Crop Monitoring Protocol. No more guesswork.
Stronger starts. Healthier crops.
One of the first signs of success was uniform germination and emergence across the entire field. Even establishment led to consistent growth, reduced variability, and a crop that developed evenly: a strong foundation for the season.
Higher quality. Higher returns.
These improvements translated into a higher marketable yield, a key success factor for farmers focused on profit and pack-out.
+1,000
extra 10 kg bags/ha in marketable yield
−50%
post-harvest waste, cut by over half
Skin set
improved: better shelf life
Uniform
greater tuber uniformity & nutrient density
Grade
better specific gravity: more meet market grade
Calcium + phosphate blends
corrected soil deficiencies
Nano-calcium
improved aeration, reduced compaction, boosted root and tuber growth
Real-time foliar adjustments
helped plants thrive throughout the season
Nitrogen → calcium strategy
reduced pest pressure and built crop resilience
"With DRIS, our nutrient strategy wasn't just correct: it was timed right, field-specific, and proven."
Together these solutions delivered a healthier crop, stronger roots and more uniform yield, proof that precision nutrition pays off.
