WHAT ARE THE BEST CARBON MANAGEMENT

PRACTICES?

Kendall Heise

Managing CO2

•CO2 Removal•CO2 emission reduction

Soil Organic Matter•Climate•Tillage•Crop Residue

•Crop Rotation•Management

Fossil Fuels•Fuel for field operations

•Equipment manufacturing•Crop inputs

Is Zero Tillage the Answer?

•Reduced residue breakdown •Reduced organic matter breakdown•Crop rotation•Moisture use efficiency

Is Zero Tillage the Answer?

•Less fuel used•Efficiency of crop inputs•Less equipment required•Equipment used fewer hours

Concerns With Zero Tillage

•N20•Fertilizer•Legumes•Mineralized nitrogen

•Crop Intensity

Conclusions

•BMP’s for GHG emission reduction are also BMP’s for $$$•Zero Tillage is not necessarily a BMP unless crop intensity is maximized•Maximizing the efficiency of crop inputs reduces GHG emissions
