Small variations of relief may change drainage and runoff and hence promote the formation of sandy surface horizons and hardened subsurface horizons (fragipans and/or duripans) in Coastal Tablelands soils. This study aimed to investigate the pedogenesis on Coastal Tablelands area with low range altimetry in Paraíba state; secondly, we also sought to contribute to the improvement of the Brazilian Soil Classification System (BSCS). Four soil profiles ware described and collected to be submitted to routine physical and chemical analysis, determination of Fe, Al and Si extracted by sulfuric acid digestion, sodium citrate-bicarbonate-dithionite and acid ammonium oxalate, sodium pyrophosphate, and mineralogical analysis in the sand and clay fractions by X-ray diffractometry. Optical density of the oxalate extract (ODOE) was also determined; the results were statistically evaluated using the R software. Microrelief variations conditioning differentiated water flows, along with the sandy texture of the surface horizons (A and E) and the lower coarse sand/fine sand ratio in the subsurface horizon, seem to promote clay accumulation in depth in the Spodosols developed on Coastal Tablelands environments. For this soils, the argilluvic (argissólico) character at the subgroup level of the BSCS should be incorporated. In addition, Al amorphous mineral phases and/or poorly crystalline play an important role in the formation of strongly cemented horizons (duripans) of the Spodosols, as also reported by other authors. Finally, the ODOE showed to be an efficient indicator of soils under podzolization process, being possible its use as a taxonomic criterion for classification of Spodosols by the BSCS.

Resumo: Observacoes feitas em ovinos da raca "Ideal", mantidos em pastagens nativas e cultivadas, indicaram alto parasitismo por Muellerius capillaris (Mueller 1889) (Nematoda: Protostrongylidae) em grande producao dos animais, o que foi feito atraves da identificacao e contagem de larvas nas fezes. Foi verificado o primeiro estadio de larvas de Muellerius: dos 129 ovinos examinados, 70 apresentaram exame positivo, o que corresponderia a 45,7% de infeccao. Necropsias de dois ovinos evidenciaram a presença de numerosos nodulos pequenos e areas enfisematosas, bem como um numero regular de helmintos adultos.

Abstract: Observations carried out in Poiwarth sheep reared in natural and improved pastures,
indicated a high infection by Muel/erius capiliavis (Muelier 1889) (Nematoda: Protostrongylidae) in a largo number of animais, through identification and counting of larvae in faes. From 129 sheep, 70 re positivo for first stage larvae in faes, corresponding to 45,7% of infections. Necropsies af two sheep showed lhe presen of numerous small noduies, enphysema areas and a regular quantity of adult helminths. |
