Calmer BT Chopper’s® confetti-like residue decays faster than stalk left behind by OEM equipment. The Calmer process returns phosphorus, potassium, and nitrogen back into the ground quicker for healthier soils and higher yields.

Dave Hula uses and recommends the Calmer BT Chopper® Upgrade Kit for John Deere corn heads.

George Roberts discusses how he calculates that operating his John Deere 843 corn head costs approx.  $1/acre to both maintain and chop cornstalks.

Do Calmer BT Chopper chopping stalk rolls turn your combine into a cultivator?

No, not really – but they do increase the profitability of your biomass, enable easier planting, and increase yields.
