The potential of agricultural soils to sequester soil organic carbon (SOC) is affected by changes in the capacity of the mineral matrix to hold and protect SOC that are brought about by agriculture. It is well established that microaggregates provide

Much effort goes into ensuring that soil and plant testing laboratories provide clients with analytical results that are accurate, reliable, and therefore, reproducible. In contrast, much less effort appears to be expended on ensuring that the analys

Comparisons of soil samples from virgin sites or sites recently planted to sugarcane (new) with sites that had been under cane production for many years (old) were made to investigate the potential impact of cane production on soil organic carbon (OC
