This experimental station is located in the Pindamonhangaba County and its main objective is to study the animal husbandry problems of regional interest. The pedological study is a part of the soil survey work carried out at Paraíba Valley (Taubaté Basin) through a cooperative project between the Instituto Agronômico and the Serviço do Vale do Paraíba. The soils of the station are derived from terciary sediments, quaternary deposits as alluvial, terraces and organic ones. The zonal soils belong to the sub-order Latosol, and include mono-typical series (soil type), Pinhão, Pinda, Polêmica, Ponte Alta, Feital, Ipiranga and Coruja as well drained soils; the Guatemala, Gleba and Campo are considered as moderate drained soils. The Tumirim series is considered as an intergrade between red-yellow podzolic and; undefined Great Soil Group of Latosol. The Ultra-zonal soils are represented by Goiabal, Ribeirão, Córrego and Mosqueada as Low Humic Gley. The Estação Series belongs to Humic Gley. The Bog soils are the Haras, Orvalho and Leitosa series. The alluvial soils, as azonal ones, are represented by Prateada, Dourada and Curtume series.
