Description
The project aims to optimize closed hydroponic systems to reuse water and nutrients through compost and its extracts, applied to the cultivation of local vegetables. Its efficiency, economic viability, and environmental impact will be evaluated, promoting sustainability and a circular economy in horticulture.
Results
Salicornia plants can be efficiently cultivated in a floating system using leachate from a previous crop, with melatonin application improving the yield and nutritional quality of the shoots. In the cultivation of "live" lettuce, the use of floating trays showed greater efficiency in vegetative growth, resulting in higher yields compared to the other hydroponic systems evaluated. The cascade cultivation system significantly outperforms soilless and soil-based cultivation in most environmental impact indicators, especially when locally produced compost is incorporated into the growing medium.
