ABSTRACT The Cerrado is a vegetation complex with a wide variety of phytophysiognomies, and sustainable management is essential for maintaining biodiversity. Morphopedology is a tool that can assist in developing plans for control of soil and land use, especially in evaluating the potential of soil erosion processes. This technique allows landscape units considered “homogeneous” to be distinguished, as a result of interaction between physiographic conditions. The aim of this study was to evaluate potential for erosion in São Miguel do […]

The aim of this work was to evaluate the relations between landforms and soil erosion of an Oxissol with geostatistical techniques in Jaboticabal (SP), Brazil, in two landform models: concave and linear. Soil samples were collected from both landforms at a depth of 0-20 cm, in a regular 50 x 50 m mesh of seven transects, at totally 412 grid points within an area of 93 ha. Physical and chemical properties were determined at each point and used to estimate the soil erodibility by indirect […]

A tilled soil has increased susceptibility to raindrop impact and sediment transport by laminar surface flow and splash, but after tillage the soil reconsolidates, increasing again its resistance. Thus, an experiment was conducted on a Hapludalf with Sandy loam soil surface, under no-tillage for eight years, to evaluate interrill erosion under different tillage methods. The experiment was totally randomized with six replicates. The treatments were recent conventional tillage (RCT), two-month consolidated conventional tillage (CCT), no-tillage with mulch (NTM) with 94% […]
