TL;DR: Overall, it emerged that there is a possible impact of ill-defined pedo-climatic conditions in the unsatisfactory performance of the models, followed by limitations in the algorithms simulating the effects of management practices.

TL;DR: In this article, the impact of change in management practices on N2O emissions in seven major soil regions in Canada, for the period 1970 to 2029, was investigated using the Denitrification-Decompostion (DNDC) model.

TL;DR: In this article, various methods used to estimate soil carbon sequestration changes due to land management change and land use change are examined to assess soil C accounting methodologies in the life cycle inventory (LCI) of agricultural LCAs.

TL;DR: In this article, the authors used the Century model to estimate the rate of organic carbon change in agricultural soils of Canada for the period 1970 to 2010, and found that the agricultural soils in Canada, whose organic carbon are currently very close to equilibrium, will stop being a net source of CO2 and will become a sink by the year 2000.

TL;DR: In this paper, the DNDC model was used to assess the effect of climate change on crop production and GHG emissions at long-term experimental sites in Canada, and the results indicated that climate change in Canada will favor increased crop production but this may be accompanied by an increase in net GHG emission for small grain production.
