Novel cropping system strategies in China can increase plant protein with higher economic value but lower greenhouse gas emissions and water use

<p>&nbsp; &nbsp; This database contains the average crop residue, manure nitrogen, manure organic carbon, net greenhouse gas emissions, and cropland area for 17 cropping systems at prefecture level during the period 2014-2018. In addition, it contained the changes of net greenhouse gas emissions caused by the optimization at prefecture level and province level.</p> <p>&nbsp; &nbsp; We also shared the key code for optimizing cropping systems at prefecture level and provided the all data. Users can run it the Matlab platform.</p>
