Technology exchange: Water treatment system AQUA4D to improve nutrient uptake and soil structure.


Project description

Most horticultural soilless systems in Almeria are designed as open systems and free drainage is due to cause accumulation of salts under the growing bags. If these soils are afterwards used for soil crops, salt toxicity may occur. In this case bell red pepper var. Melchor plants are grown on coir lying directly on the natural soil (enficonado system ©). To assess the AQUA4D effect, it has been installed in an irrigation plot of 1250 m2 and will be compared with a second irrigation plot of equal area but no AQUA4D system. Four Rhizon soil moisture samplers were installed in both irrigation plots in order to evaluate the effect on the soil solution and yield.

Expected results

The electromagnetic treatment of the nutrient solution improves the nutrient uptake and the soil structure so we expect an improvement of the pepper yield.

Repeatability & Applicability

This showcase can be implemented in any irrigation system.
