“…Although this fact has not been observed in the present study, many studies show the effect of cattle trampling on the soil surface layers (Bertol et al 2000;Chancellor et al 1962, Costa et al 2000Gradwell, 1960 ;Vzzotto et al, 2000).…”

RESUMOAtributos morfológicos, físicos e pedogenéticos relacionados com a "produção de água" em microbacias do município de Guarapari, ES, BrasilAs características dos solos relacionadas com a gênese, uso e manejo adotados são importantes fatores na dinâmica da água em bacias hidrográficas. Neste trabalho, avaliaram-se alguns atributos morfológicos, físicos e pedogenéticos, relacionados com o potencial de produção de água em microbacias do município de Guarapari, ES. Soil characteristics related to the genesis, land use and management are important factors in water dynamics in watersheds. This study evaluated physical, morphological and pedogenetic attributes related to water yield potential in small watersheds in Guarapari, ES, Brazil. The following representative profiles were selected, morphologically described and sampled in area of Atlantic Forest domain: Lithic Udifolists, Oxyaquic Udifluventes, Typic Paleudults, Typic Hapludults, Typic Hapludox, Oxic Dystrudepts and Typic Endoaquents. Samples were collected in the soil profiles for physical analysis. Measurements of field-saturated hydraulic conductivity and soil penetration resistance were perfomed in some profiles, which were under different uses. The Endoaquents of Limão Creek can be considered efficient as temporary water reservoirs. However, the use of artificial drainage tends to reduce this effect. Differential erosion was detected by the sand texture on the surface of the Typic Paleudults due to the low degree of clay flocculation, slope, high resistance to the penetration and low hydraulic conductivity of the Bt horizon, making it necessary to adopt soil management practices to increase the water infiltration. Under pasture, mainly in the cattle trails where the trampling is more intense, there was high resistance to penetration in the superficial layers of the Typic Hapludults. The Typic Hapludox have the greatest potential for water yield in the small watersheds because of its greater extent in the headwaters and their morphological and physical characteristics, which can result in increased aquifer recharge.

“…A study conducted by Capurro et al (2014) found a higher density in the 0.09 to 0.12 m layer and associated this result with accumulation of pressures imposed by animal trampling. Another study by Vzzotto et al (2000), also evaluating the changes in physical properties of an Albaqualf soil subjected to cattle trampling, found reduced porosity and increased BD in the top 0.05 m layer.…”

ABSTRACT:A compacted subsurface soil layer can be a limiting factor for soybean growing, reducing soybean yield. The aim of this study was to evaluate the effect of different tillage systems on the physical properties of two Albaqualf soils of the Central Plains region in the state of Rio Grande do Sul in southern Brazil. Two experiments were conducted: one in Santa Maria, RS, during the 2013/14 and 2014/15 crop seasons, and another in Formigueiro, RS, during the 2013/14 crop season. A randomized block experimental design with four replications was used. The treatments were: sowing using an offset double disc (T1); sowing using a fluted coulter disc (wavy disc with 12 waves) (T2); sowing with a knife runner opener (T3); sowing with a knife runner opener + press wheel mechanism for ground levelling (T4); sowing using a furrow opener upon a raised bed (T5); and chisel plough + sowing using an offset double-disc (T6). In the 2014/15 growing season, the T4 factor was changed using a knife runner opener 0.05 m from the planting row. A smaller reduction in the compacted subsurface soil layer was observed for both T1 and T2, which exhibited high soil bulk density values for the 2013/14 and 2014/15 crop seasons. Furthermore, T3, T5 and T6 led to a reduction in bulk density, and increasing total porosity and macroporosity in the soil, which consequently increased water infiltration, water storage capacity, and crop yield in areas with the presence of a compacted subsurface soil layer.

“…In intensive grazing systems, where the cattle remain in the same pasture for a long period of time, the movement of these animals reduces vegetation cover. Trampling can kill young plants or damage mature plants, compact and destabilize the soil surface and increase the area of bare soil (e.g., Vzzoto et al 2000). These effects may increase soil erosion and consequently the degradation of grasslands, negatively impacting the dung beetles assemblage.…”
