! Pasture, Fazenda Nossa Senhora da Aparecida, Ji-Parana 
! the observed soil texture is loamy sand
!  0 - 0.05m: clay%=9; sand%=85; silt%=6

!
! The surface soil was a sand/loamy sand (85% sand). 
! The clay content increased gradually with depth from 7% in the top 0.1m 
! to 35% between 1m and 1.5m, where the texture was sandy clay loam. 
! Between 1m and 2m, the soil was gravelly (28% w/w), merging into saprolite below 2m. 
! Bedrock was not encountered within the upper 3.8m of the profile. 
! Roots were sometimes found concentrated in the channels left by rotted tree roots. 
! The bulk density decreased from 1.5 Mg/m3 (42%) at the surface to 1.24 Mg/m3 (52%) at 1.35m.
