Modelling the mineralisation of plant residues on the soil surface

Axel Berkenkamp, Eckart Priesack, Jean Charles Munch
2002 Agronomie  
The results show that the new model is able to describe the C and N turnover of crop residues in more detail, including the decrease of soil cover observed in the field. crop residues / decomposition /  ...  A general assumption in many agroecosystem C and N turnover models is that the decomposition of added organic matter starts at the moment of residue incorporation into the soil.  ...  First, we estimated the model parameters for the new soil C and N turnover model by taking the parameters of the previously used SOILN turnover model [27] as starting values for a new calibration.  ...

2012 Agronomy Journal  
In other words, a search for the best trade-off between the heuristic role of a model and its utility for decision-making emerged.  ...  Hence the need arose to search for compromises between at one side the mathematical and numerical properties of crop models (parameterization, uncertainty, computing time), and at the other side the scope  ...  Our modeling practices, the idea of writing this article, and the way we discussed the positions found in the literature have all been influenced by their views based on their great experience in "model  ...

2019 Journal of Environmental Management  
In this study, we assess the capabilities of various types of meta-models to emulate the complex process-based Volt'Air for estimating NH3 emission rates from N fertilizer and manure applications.  ...  However, these models require a large number of input variables and their implementation on a large scale requires long computation times that may restrict their use by public environmental agencies.  ...  The methods are based on different types of models whose parameters are estimated using an optimization algorithm implemented with R functions of specific R packages.  ...
