Stubble Initiative: Modelling the effect of residue management on soil nitrogen dynamics and crop production

This data collection includes the data generated under the modelling component of a GRDC project. The APSIM model was optimized using data set collected from Termora, Horsham, and Karoonda to simulate observed soil mineral nitrogen dynamics, water dynamics, residue recovery and crop production. The key outputs are the optimized two model parameters: the decay rate constant of humic organic carbon and carbon use efficiency of microbial decomposition.
