Overall, soil CEC and SOC content was greatest in the 0.2 and 0.2-2 m fraction, indicating that size, and probably type, of SOM influenced CEC... Kaiser et al. (2003) found that soils with a high content of black carbon showed increased sorption ability compared with plant- and microbial-derived SOM... Addition of organic amendments can increase P availability to plants by decreasing the P adsorption capacity of soils...

The potential for changes in soil microbial function for improved productivity through intensive cropping systems were evaluated in this project... A resilience test in which soils are exposed to repeated wet-dry cycles provides a suitable assay to determine changes in the stability of microbial functions... Results from the project demonstrated the likelihood of changes in microbial functions relevant for increased nutrient efficiency and productivity by altering C inputs through the use of intensive cropping systems...
