Improved nutrient uptake

Extensive experimental work demonstrated that using H2Pro TriSmart or H2Pro AquaSmart would significantly increase soil water potential and base water potential (A & B). The application of wetting agent adjusted the physical status of the water in the soil, by lowering surface tension forces, making it easier for plant roots to extract.

The experimental work demonstrated a significant increase in plant ‘rhizosheath’ following applications of H2Pro TriSmart and H2Pro AquaSmart (C). The rhizosheath is the volume of soil intimately associated with the plant roots and root hairs. Increasing the rhizosheath soil, could be an additional mechanism by which the wetting agents could be influencing plant water uptake – especially in a drying soil situations, maintaining higher water VMC closer to the roots.

A final experiment on wheat and barley demonstrated a significant increase in dry shoot biomass following applications of H2Pro AquaSmart (D). This would indicate the plant is better able to access nutrient resources following wetting agent application, however, no significant increase in tissue N, P or K content was measured.
