Activity C.8: Optimizing fertilization and irrigation management for a closed greenhouse organic tomato growing system

Objectives:

1. Adjust nitrogen and water supply according to plant physiological stage, soil biological activity (mineralization rate) and greenhouse climate;
2. Reduce nitrogen and water emission into the environment by better nutrient and water management adjusted to plant needs;
3. Evaluate the suitability of different cultivars for organic growing systems;
4. Improve fruit quality by better fertilization and irrigation management;
5. Characterize and assess compatibility of available certified organic fertilizers;
6. Evaluate mineralization rates and nitrogen availability of those available certified organic fertilizers in the growing medium;
7. Evaluate the sustainability of this organic growing system
