Metadata only record This study evaluates the impact of cultivation on soil organic matter loss in North American grassland soils by measuring numerous aggregate- and nutrient-related soil indicators. Macroaggregates were more stable in native soil than in cultivated soil. In both soils, more C, N, and P were present in macroaggregates than in microaggregates.
