Within the R&D-project StaPrax-Regio, highly efficient N-stabilized fertilization strategies will be identified based on site-specific agrometeorological and soil characteristics. Derived strategies will be transferred to fertilization practice using innovative advisory tools. The aim of the project is a significantly improved utilization of the diverse and complex beneficial effects of N-stabilized fertilization (e.g. reduction of N losses, improved N availability in soil, promotion of root growth, improvement of seedling development) to optimize fertilizer N efficiency. Currently, this has been insufficiently achieved in winter cereals. However, in the previous project StaPlaRes it was demonstrated that a significant increase in N use efficiency can be achieved by an optimized adaptation of N-stabilized fertilization strategies to site-specific soil and weather conditions. Site-specific fertilization strategies will result in a nationwide approach of improving fertilizer N efficiency. The following workflow and sub-projects are planned: (a) Carrying out of practical field trials using the most important cereals at about 20 different cropland sites to test various stabilized fertilization strategies; (b) accompanying agro-meteorological studies; (c) accompanying soil N-turnover studies; (d) identification of site-specific fertilization strategies based on local meteorological and soil-specific constraints; (e) GIS-based visualization via high-resolution maps of site parameters relevant for fertilization, i.e. N loss potential, N availability potential, and targeted fertilization strategies; (f) integration of project outputs into novel advisory tools (e.g. BESyD, ISABEL, regionalized SKWP fertilization advice). Thereby the project provides a substantial contribution to a sustainable use of resources, to improve the market share of stabilized fertilizers and to enhance the acceptance and competitiveness of German agriculture.
