Reconsider the importance of soil organic carbon

Abstract

The pursuit for better agricultural productivity and profitability over the years has resulted in a decline in soil organic carbon globally, and the cotton production system is no exception.When compared to surrounding remnant native vegetation, most cotton fields have a significantly lower soil organic carbon (C) content, and it is likely to continue to decrease if current management practices are maintained. Dr Oliver Knox, who leads the CRDC-funded Soil System Research project says the consequences of such decline can be devastating in cotton production.
