Stability, morphology and roughness of aggregates of typical Argiudolls under different types of land uses: Their role as indicators of soils physical quality in Buenos Aires province, Argentina

During the last ten years, an important land use change took place in the Pampas region of Argentina. This change led to a significant soil degradation. This work aims to evaluate the stability, morphology and roughness of soil aggregates in soils under different land uses. The values found for each...
