There are various methods for assessing data on infiltration rates, but it is important to know how these methods interact with soil properties. The objective of this paper was to analyze four methods for infiltration measurement in different soil types under a no tillage system. Field experiments were performed in Campinas, Campos Novos Paulista and Pindorama, in São Paulo State, on Eutrudox, Hapludox and Hapladult soils, respectively. Infiltration rates were measured from September to November 2000, by the evaluation methods: […]

The spatial variability of soil water infiltration rate and A horizon thickness were studied in a Red-Yellow Podzolic soil (Kandudalf) showing erosion signs, located in Vera Cruz, SP. Field measurements were taken in regular 5 meter spacing square grid, resulting in 64 sampling points where the infiltration rate at the A, E and B horizon, and A horizon thickness were determined in coffee, pasture and natural vegetation. Statistical analysis showed high variability in the soil water infiltration rate and in […]
