Building soil carbon for productivity and carbon accounting

Plain text source: 
As an example, where appropriate use of fertilisers can increase productivity beyond that currently being attained, adjusting the amount or timing of fertiliser application would result in greater carbon inputs to the soil... Recent research results have also noted that the proportion of residue carbon that is retained in a soil to enhance soil carbon stocks can be enhanced by ensuring that enough nutrients exist in the soil to both satisfy the crop requirements and the requirements to build soil organic carbon... If we use the same bulk density as above (1.2 g/cm3) and restrict our calculations to the top 10 cm of soil where organic carbon is most easily increased, at 2% carbon the soil would contain 24 tonnes C/ha...
