At a basic level, some models invoke, for example, a physical protection of organic matter as a function of clay content, but to our knowledge, no model explicitly accounts for thermal decomposition of hydroxylamine or the catalysis of reactions by metal species, although DNDC
purportedly tracks oxidation-reduction reactions over a range of potentials.
The online Performance Metrics system offers a simplified, user-friendly version of the DNDC tool that enables winegrowers to customize the variables that are the most significant drivers of soil-related greenhouse gas emissions in vineyards.
Department of Agriculture Agricultural Research Service and other project partners for several years to calibrate and validate the DNDC model for winegrapes, assess the influence of vineyard management practices on greenhouse gas emissions and create a user-friendly tool for use by California winegrowers.
Thus, the combined investigation of biological processes (considered extensively in models such as DNDC
and ExpertN with the exclusion of dynamics of metal cations) and geochemical processes (considered in models such as PHREEQC2 and Minteq where nitrification is not yet sufficiently considered) should receive more attention in research if the aim is to advance the knowledge of nutrient dynamics and the prediction of long-term effects of N fertilisation on base cation availability.

Some of the models simulate the dynamics of the microbes that are responsible for soil nitrification and denitrification, such as a process-based model, DNDC (Denitrification and Decomposition; Li et al.
1998) and included a daily trace gas version of the CENTURY (a forerunner of DAYCENT), DNDC, CASA, and ExpertN models.
