3.4. I am already receiving a carbon payment on some of my crops (such as oilseed rape), can I register with Soil Capital Carbon?
No. You cannot sell the carbon twice. As Soil Capital Carbon assesses all your crops in rotation, it is not possible to exclude a crop (such as oilseed rape) that is already receiving carbon payments. So you have to choose: get a carbon payment on an individual crop or get carbon payments on your whole farm.
