Short-term variation in aggregation and particulate organic matter under crops and pastures by Freibauer, A., Westerhof, R, Ayarza, Miguel Angel, Silva, J.E. da, Zech, W.

“…Short-term changes in soil aggregation, total and particulate organic C and N were studied in cropping and pasture systems of the Brazilian savannas, also known as the Cerrados. Furthermore, the concepts of a hierarchical aggregate structure and of the interaction of soil structure with particulate organic matter (POM) available for temperate soils were evaluated and modified for tropical Oxisols. …”
