You have to sell your credits threw a "Aggregater" as they sell lump or parcels of credits rather then individuals doing it. ie Farmers Union in some states. Most places have set rates for zero till, wetlands and some for enhanced range land. Some area can't seem to get it on native prairie just seeded perennials.

 You need records for the practices that you use.

 I have heard that carbon prices have come down with the price of oil and steel.

 I look forward to others input and if anyone has got some sold.
