Abstract

. In this work the morphological and chemical characteristics are compared on the deck of the subtypes, fluffy and vertic, addition of relations between structural stability and organic matter in the soils evaluated. The samplings were conducted in soils under different management systems in the municipalities Ranchuelo and Santa Clara. The indicators studied were soil pH, calcium, value T, organic matter, structure factor and the stable aggregates. The results show that in both subtypes there is a strong relationship between soil properties, organic matter, structure factor and the stable aggregates which confirms the importance of these properties as indicators of the soil quality related to the management.
