Abstract | The development of the CANDY system (CArbon and Nitrogen DYnamics) has been based on experience of organic matter turnover and nitrogen dynamics gained over a long period, a major part of the scientific work in Bad Lauchstädt. The main objective in developing the model was to give farmers a tool for calculating short term dynamics of nitrogen transformations and long term changes in the carbon content of the soil. For this reason the system consists of a database interface and several model components. The main component is the CANDY module, written in TURBO - PASCAL which calculates daily changes of water, temperature, carbon and nitrogen for a 2 m deep soil profile. Alongside this daily-timestep nitrogen simulation, there is a long term carbon module that calculates the amount of decomposable carbon in steady state for a given crop rotation. The calculation is specific to the site and management practices and is based on averaged turnover conditions, yields and inputs of organic material. |
