Influence of the relief and erosion in the space variability of an oxissol in Jaboticabal, state of São Paulo, Brazil
01/Dec/2003
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 […]
