Organic matter in soil size and density fractions from maize and legume cropping systems

Abstract

Soil organic matter (SOM) plays an essential role in biologically-mediated nutrient availability. There is, however, a lack of functionally-defined measures of SOM. We analysed C and N in particle-size, density and size-density fractions of SOM in order to identify the measures of SOM most affected by maize and legume cropping systems. Soil was collected after the eighth cropping season (4 years) from an experiment on a Kandic Rhodustalf in Kenya. Total organic C and N in whole soil (WS) were not significantly (P
