Reduced tillage and green manures for sustainable organic cropping systems


Aim of the research project is the optimized adaptation of reduced tillage to the needs of organic crop production. TILMAN-ORG is sponsored by funds of the European Core Organic II programme. The project consists of partners from 14 universities and research institutes of 11 European countries. The Department of Organic Farming & Cropping will contribute by developing green manure systems for improved nutrient management in cropping systems of reduced tillage. Main focus will be given on the effect of different tillage intensities and dates for the incorporation of green manures upon the N- and C-status of the soil. Additionally, the achieved data of some partners will be used as reference for the soil-N simulation model NDICEA. It is planned to proof model-based predictions for N dynamics in response to expected yields within different scenarios of reduced tillage and different green manures. Others outcomes of the project will be (a) the writing of two handbooks for improved management of soil and plant sampling and improved predictability of soil and plant analyses, (b) testing of innovative methods of weed regulation in order to facilitate the implementation of reduced tillage in organic crop cultivation.
