Sugarcane, carbon sequestration and food supplies [Full subscriber]

Sugarcane growers can make disproportionately large contributions to the great global issues of carbon sequestration to combat global warming, and to the provisioning (in the broadest sense) of the burgeoning populations of Africa and S/SE Asia. The key to both is a substantial increase of Soil Organic Matter (SOM); increasing levels worldwide by one-third would deplete atmospheric CO2 levels to near zero. Sugarcane growers can play their part through embracing trash mulching and minimum tillage; but additional field experiments are needed to define best techniques. Increased SOM will improve yields and water-use efficiencies, and reduce erosion. The ultimate development of…
