Efficacy trials

Aquaholder has been tested in laboratory and field trials where it has proven its benefits. Tests were carried out in various regions of the world in both dry and standard conditions where the product has shown a positive impact on plant development in the early stages of growth and thus ensured a better start, creating conditions for better yields.

Strategic conclusion

AQUAHOLDER should be positioned as a seed-zone moisture-management and abiotic-stress-mitigation technology, rather than as a universal yield stimulant. Across Good Experimental Practice (GEP) trials in maize (corn), sunflower, winter oilseed rape (OSR), and sugar beet, the consolidated evidence shows a consistent root-first biological response: stronger early root development, improved vegetative growth, faster and more uniform crop establishment, and excellent crop safety.

The clearest commercial value occurs when seed-zone moisture is limiting and soil physical resistance is high, particularly under drought on medium-to-heavy loam and clay soils. Under timely rainfall or irrigation, treated crops can retain early-vigor benefits, but untreated controls may catch up, narrowing or eliminating final-yield differences. AQUAHOLDER should therefore be marketed as establishment and drought-risk insurance, with crop- and site-specific positioning.

Crop-specific performance

Crop Main biological response Key quantified outcomes Principal commercial value
Corn (maize) Rapid fibrous-root and early-vigor response, especially in dry, compacted clay soil
  • Root dry matter +24.4%;
  • shoot dry matter +16.1%;
  • early stand density +19.9%;
  • average drought yield response +6.41%;
  • heavy/clay × drought yield response +8.79%
 Improved establishment and drought protection, with potential harvest-management benefits from lower grain moisture and improved grain quality
Sunflower Better taproot penetration and establishment in drying, crusting, shrinking, or mechanically resistant soils
  • Root biomass +12.9%;
  • shoot/stem biomass +11.5%;
  • early plant density +21.5%;
  • average drought yield response +6.43%;
  • 16 of 18 yield-assessed trials positive; flower-head diameter +11.0%
 Most consistent conversion of early vigor to harvest performance; strong flower-head response and high potential on dry clay
Winter OSR Enhanced autumn rosette, root reserve, and shoot development before winter
  • Root dry biomass +18.2%;
  • shoot dry biomass +17.8%;
  • emergence +7.0%;
  • average drought yield response +3.01%;
  • leaf number +4.7%;
  • medium/loam × drought yield response +4.29%
 Establishment stability and rosette development before winter, especially under post-sowing drought on loam soils
Sugar beet Strong early taproot and canopy response, with potential industrial-quality benefits
  • Root dry mass +24.3%;
  • shoot dry mass +20.0%;
  • emergence +11.9%;
  • significant root or sugar-corrected yield gains in 5 of 10 harvested trials, averaging +7.2%
 Root yield and processing quality, including polarization increases and lower molasses-forming impurities; requires strict sowing-condition screening
