As an agricultural scientist, I always feel slightly uncomfortable when biofuel producers start talking about using 'agricultural waste'. Increasingly, this 'waste' is now used by farmers as an integral part in boosting soil carbon and increasing biological activity as it breaks down, improving soils and improving subsequent crop yields.
The value of this, though often difficult to measure is significant and very real. But I worry shortsighted farmers looking for a quick buck may lose these less tangible benefits, leading to further soil degradation and lower yields in the future.
