This document summarizes several projects that received funding from the European Union to develop and demonstrate technologies for improving water and nutrient use efficiency in soil-grown crops. It describes 9 showcase projects from different partners across Europe that tested sensors, decision support tools, and other technologies for more precise irrigation management and reduction of overfertilization. The projects monitored soil moisture, nutrients, and plant parameters in various crops like tomatoes, peppers, olives and more to optimize fertigation according to real-time crop needs.
Technologies to Improve Water and Nutrient Use Efficiency in Soil Bound Crops
