  abstract = {{T}he {C}errado region, with over 50 million hectares of cultivated pasture, provides 55% of {B}razilian beef production. {P}revious investigations have shown that about 70-80% of this pasture is affected by some kind of degradation, leading to low productivity. {H}owever, until now, few surveys have been carried out on a regional scale. {T}he aim of the present work is both to assess the fertility and acidity levels of {C}errado soils under pasture and compare the variability of the soils characteristics on a regional scale. {T}wo soil depths were sampled in different places within the studied area: (1) a surface horizon (0.0-0.2 m) in order to evaluate its fertility and acidity status for pasture, and (2) a subsurface horizon (0.6-0.8 m), used for classification. {M}ost of soils had levels of nutrients below the reference values for adequate pasture development. {W}hatever the texture, about 90% of soils had low or very low availability of phosphorus. {O}nly 7 to 14% of soils had low p{H}, high exchangeable aluminum, and aluminum saturation above the critical acidity level. {E}xcept for nitrogen, no significant difference was found between {L}atossolos {V}ermelhos and {L}atossolos {V}ermelho-{A}marelos.},
