In order to minimize nutrient losses and compensate for nutrient imbalances, within the framework of “Nutri@ÖkoGemüse” nutrient management strategies are to be developed which aim to achieve more targeted and balanced fertilization in intensive organic vegetable cultivation systems. An essential instrument for improving nutrient efficiency is the introduction and improvement of computer-aided programs in practice (e.g. N-Expert, NDICEA). The implementation of EDP-supported systems and digital applications should enable balanced and efficient fertilization management on farms for vegetable growing practice. These software tools should on the one hand support farmers in estimating the course and level of N mineralization and the course of N uptake of crops. On the other hand, compensated balances for N, P, K and S should be considered.
Vegetable-growing advice and practice will be given an instrument that will help to achieve appropriate and balanced fertilization that takes into account not only nitrogen, but also other macronutrients
