Infiltration characteristics of red sandy loams under different land use systems.

A study was conducted in Agroforestry Research Unit, Hyderabad. Andhra Pradesh to analyze the impact of different land use systems on infiltration characteristics through their effect on soil aggregation. The results revealed that infiltration rates were of moderate nature in all the systems, highest being in agri-silvi-horti system (6 cm h−1). Cumulative infiltrartion, however, was highest with silvi-pasture system (17.33 cm) followed by agrisilvi-horti system (17-16cm). Both infiltration rate (2.2 cm h−1) and cumulative infiltration (6.83 cm) were lowest in uncultivated land where in degree of aggregation was also lowest. The degree of aggregation in terms of aggregates > 0.25 mm and mean weight diameter were significant.
