Grass pastures, if well-established and managed, play an important environmental role as soil cover, for aggregate formation and stabilization and in the reduction of dense or compacted layers. The objectives of this study were to quantify the least limiting water range (LLWR) of a physically degraded Red-Yellow Latosol (Oxisol) on which bermudagrass (Cynodon spp., cultivar coastcross) was planted, and to use the LLWR as an indicator of changes in the soil structural quality. Undisturbed samples were collected in volumetric rings […]
