GRK 1397: Regulation of soil organic matter and nutrient turnover in organic agriculture
Project
Project code: 20025697
Contract period: 01.01.2007
- 31.12.2010
Purpose of research: Basic research
The regulation of the budget of soil organic matter (SOM) and nutrients by management is a central focus in agriculture, especially in organic agriculture. The budgets of SOM and nutrients determine soil fertility, i.e. the long-term productivity of soils. However, the underlying processes of soil fertility in organic agriculture are not well understood.
The interdisciplinary research project, therefore, deals within the scope of 12 Ph D theses on the possibilities to regulate soil organic matter and nutrients budgets by soil management, crop rotation and by feeding strategies via the quality of the manure. The focus is to be on
(i) the quality of inputs (crop residues, organic fertilizers),
(ii) the turnover of litter and SOM, especially carbon, nitrogen and other relevant nutrients (Ca, K, Mg, PO4),
(iii) gaseous (CO2, CH4, N2O, NH3) and liquid (NO3, dissolved organic carbon, cations) outputs and
(iv) the coupling of these aspects by modelling.
