Optimization of nitrogen efficiency and soil fertility through an integrated consideration of soil nutrients in potato, wheat and sugar beet crops
Project
Project code: EIP-Agri-Bay-2023-PPGBDÜBW
Contract period: 01.01.2023
- 31.12.2025
Budget: 84,858 Euro
Purpose of research: Applied research
Keywords: plant production and horticulture, fertilisation, soil, water, climate change
Nitrogen (N) in excess originating from agricultural sources, results in nitrate leaching into ground/surface waters and airborne emissions. Measures to reduce these emissions consider a reduced N-supply and an increase in N-efficiency. From a previous EIP-Agri the potential for optimized N-efficiency in winter wheat through yield-zone-specific soil analysis and subsequent fertilization according to the Albrecht method could be elaborated. The Albrecht method recommends fertilization based on a soll analysis of micro- and macronutrients regarding the soil and the effect and interaction of the individual nutrients. As a result of the previous project and practical experience, a follow-up project will be developed and prepared with the aim of developing a fertiliser strategy. The following requirements should be considered in the planning: increasing N efficiency by reducing N emissions, feasibility in heterogeneous fields, cost reduction as well as increasing soll fertility.
