Copy link Optimized Water Uptake with H2Gro ED
higher water uptake
Weihenstephan, Germany
higher water uptake
Key Conclusions
- 20–30% higher water absorption after H2Gro ED treatment
- Improved re‑wetting behaviour across multiple irrigation cycles
- More uniform water distribution within the substrate
- Enhanced substrate performance under repeated wetting conditions
Objective
To evaluate how H2Gro ED improves water absorption and re‑wetting behaviour in peat‑based substrates during repeated irrigation cycles.
Trial Details
Trial station

H2Gro
Treatments
The trial was conducted in Weihenstephan, Germany using a peat‑based substrate to evaluate the effect of H2Gro ED on water absorption and re‑wetting behaviour.
H2Gro ED was incorporated into the substrate at a rate of 150 ml/m³, while an untreated peat substrate served as the control. After initial saturation, the substrate was subjected to repeated irrigation cycles, and the volume of water absorbed was measured from the second through the eleventh wetting‑up. This setup allowed assessment of how consistently the treated substrate could take up water during repeated re‑wetting events, reflecting practical irrigation conditions in commercial horticulture.

Results
Across wetting cycles 2–11, the peat‑based substrate treated with H2Gro ED absorbed 20–30% more water compared to the untreated control.
This improvement was consistent throughout the repeated wetting cycles, demonstrating that H2Gro ED enhances both initial wetting and subsequent re‑wetting of peat‑based media.
