Project
Project code: 2818OE063
Contract period: 01.03.2019

Nutri@ÖkoGemüse aims to improve the nutrient management in organic vegetable production systems, in order to implement more balanced fertilization systems. The base will be status quo analyses in farms in different regions of Germany in order to collect data about nutrient balances and soil nutrient status, in cooperation with the project 'NutriNet'. A key instrument aiming an improvement of the N efficiency of vegetable systems is the imple-mentation of decision support systems for modelling soil N mineralization and nitrogen up-take by the plants. Therefore, different computer programs for assessing field N household (e.g. N-Expert, NDICEA) will be implemented in farms in order to test their suitability for improvement of the overall N fertilization. This approach will be complemented by field experiments to test approaches to increase the nitrogen inputs via biological nitrogen fixation in the cropping system, as well as the fertilizer value of alternative fertilizers. The approach-es to increase the N inputs via biological nitrogen fixation included the implementation of leguminous 'living mulches” (e.g. small white clover species) intercropped with vegetable row crops (e.g. kale) and legume winter green manure crops (e.g. peas, vetch, faba beans). In the field experiments on the fertilizer value of alternative fertilizers aimed to test the N re-lease of clover grass based fertilizers and process waters in different regions of Germany in open field vegetable fields and in greenhouses. The influence of soil characteristics on N release will be tested in incubation experiments in order to improve our knowledge about the interaction or soil and organic fertilizers. Coordinators of the project will be the Landwirtschaftliche Technologiezentrum Augusten-berg (LTZ) and the Technical University of Munich (TUM).
