A couple of problems with using field waste as fuel feedstocks is that this removes the use of this to enrich the field-soil. This will mean the need to use more fertilizers and currently most fertilizers are derived from fossilized hydrocarbon feedstocks, and ultimately are adding previously sequestered carbon back into the environment. I've no problem with using some organic agricultural waste for this purpose, but for the most part, there are a lot of agricultural practices that we are going to have to modify and adapt if we are going to begin minimizing our reliance upon oil and gas, and still maintain high agricultural output.
