Crop residues that are left on the field/incorporated/mulched increase emissions, but not soil carbon. Does this part of the tool take into account the effects of both humification and mineralization?


This section only considers the nitrogen emissions from the mineralization of the residues (emissions). In the past, the Cool Farm Tool also estimated the potential soil carbon increase from leaving the residues in the field (carbon storage. However, this increase would only happen if this is a management that has been changed recently (past 20 years). For all other cases, the soil carbon would be in equilibrium and no additional carbon is stored (see answers on soil carbon change).
