The present invention relates to agricultural practices for maximizing carbon sequestration, enhanced productivity, sustainable farming and minimizing greenhouse gas emissions. In one embodiment, there is provided a method comprising: planting a Brassica carinata variety as a second crop in rotation with a first crop or to replace fallow； implementing land management practices to reduce the use of fossil fuel inputs and to maximize the capture of atmospheric carbon by the plant material of Brassica carinata； harvesting of the Brassica carinata variety to obtain the grain； and returning about 70% to about 90% of all plant material from the Brassica carinata variety aside from the grain to the soil. As a result, the overall greenhouse gas emissions associated with agriculture are reduced. In some embodiments, the method further comprises producing grain for use in the production of a plant-based feedstock for producing low carbon intensity fuels； for adding carbon in soil； and/or acquiring a carbon credit.
