“…Additionally, clumped grass growth can promote bare soil with greater impact of animal hoof pressure. Consequently, there is a greater tendency for compaction, which was confirmed after grazing due to greater penetration resistance (Fernández, Alvarez, & Taboada, 2015). The threshold for BD suggested by Reichert et al (2003) is 1.65 kg dm -3 .…”

Soils under pastures suffer physical modifications, in greater or lesser intensity, via the action of animal trampling. Thus, the aim was to evaluate the spatial dependence of soil physical attributes under bovine trampling. The trial was performed at Roçadinho Farm, Agreste of Pernambuco, Brazil, in a 40 x 40 m paddock that was managed with continuous stocking by bovines and 12 AU ha-1 stocking rate. Soil samples were collected before and after grazing using a 6 x 6 m grid, totaling 36 sampling points. At each point, the bulk density, total porosity, moisture, soil penetration resistance at 0.00-0.10, 0.10-0.20, and 0.20-0.30 m depth were estimated, as was the hydraulic conductivity on the saturated soil surface. Descriptive statistics and geostatistics supported the data analysis. A normal distribution was verified for all variables, which were scored as either low or high variability in terms of the variation coefficient. The physical attributes (density, total porosity, moisture, soil penetration resistance and hydraulic conductivity) of the soil sampled presented a strong spatial dependence before and after grazing.

“…This may be associated with soil particle distribution due to yak trampling, leading to top soil aggregate disruption (Fasinmirin, 2015;Fernández et al, 2015). Grazing-excluded sites soil particle analyses showed fine sand and silt contents were significantly greater than that in grazing zones (P < 0.05) (Fig.…”

“…According to these authors, soil bulk density (BD) increased from 1.0 to 1.3 g cm −3 in the top 5-cm layer, while IR decreased from 29 to 11 cm d −1 in the grazed areas. Meanwhile, Fernández et al (2015) compared the grazing effect on the physical properties of silty loam and sandy loam soils of Argentina under NT for 4 yr. They observed that BD decreased from 1.25 to 1.1 g cm −3 in the 1st year of measurement due to grazing, but only in the silty loam soil.…”

Adopting no-till (NT) after conventional tillage (CT) could affect surface runoff, but this effect may also depend on the rotation type, such as continuous grain crop (CC) or crop-pasture rotation (CP). The objective of this study was to assess the effects of soil-tillage practices and rotation type on runoff in a long-term field (LTF) trial established in 1993 on a Mollisol. This experiment was carried from 2012 to 2017 and included three tillage rotations (NT-CP, NT-CC, and CT-CP) and a natural pasture (NP) as a control, with three replications. Runoff was monitored under natural rainfall in microplots. The pasture of the CP treatment was rotationally grazed with dairy cows at high stocking rates before this experiment. We hypothesized that soil compaction by animal trampling during grazing would increase surface runoff regardless of tillage type. We measured the number of events and runoff depth in all treatments, grain yield, soil bulk density (BD), and infiltration rate (IR) in NT-CP and NT-CC. The results showed a statistically significant increase in average runoff (107 mm yr -1 ) for all rotations relative to NP (68 mm yr -1 ) and a significant difference for the mean of both CP rotations (119 mm yr -1 ) compared with NT-CC (83 mm yr -1 ). During the crop phase (excluding the pasture), the two NT rotations showed a similar trend, but with higher BD (1.23 g cm -3 ) and lower IR (27.2 mm h -1 ) for NT-CP. We concluded that animal trampling increased surface runoff regardless of tillage, but this effect would need to be confirmed at other sites.
