I personally don't like the idea of carbon credits because you can just bet if there is any sort of payments involved to benefit the farmer there will soon be payments calculated that he owes based on the fossil fuels he uses in the form of diesel,gas, propane for drying, and commercial fertilizer.  

However, in all the talk about carbon credits I've not heard anything discussed about what an acre of wooded area  would be worth in the credit market. An acre of trees would surely be worth a whole lot more than cropland as a form of long term carbon sequestration. Yet once again every time a tree was cut or a fencerow taken out their could be a penalty the farmer ends up owing.

Sounds like just another attempt to legislate away our personal  rights as property owners in exchange for a very small amount of money and a whole lot more exposure to someone else's whims and controls.
