“…An evaluation of the compaction of the soil surface caused by 120 bovines grazing in a 100 x 70 m pastureland during three weeks by Tuffour, Bonsu, and Khalid (2014) found that grazing at any intensity affected the soil water infiltration because the animal hoof pressure greatly reduced the porous space of soil, which supported our results.…”

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.

“…In addition to this, the analysis also indicated a correlation of the mentioned properties with the BD, SWC, and WHC. Higher BD and SWC were found to reduce PT and RT (Smith, 1972;Tofour et al, 2014), reduce IR (Tuffour et al, 2014), and with it increase SL (Biddoccu et al, 2017). The slope was found as an insignificant variable in this analysis due to no significant differences observed between the treatments.…”

Eroded lands have deteriorated soil physical, chemical, and biological properties which reduces their productivity and represents a great threat to environmental safety and ecosystem stability. This study aims to investigate the soil management effect on the soil properties and conversely on soil erosion in vineyards by comparing tilled (TV) and permanently grass-covered vineyard (GCV) plots. The study vineyard is located in Sisak-Moslavina County, Croatia (45°31' N, 16°43' E). The fieldwork comprised of 8 rainfall simulations, soil sampling, and collection of overland flow. The results showed that TV plots had lower (P<0.05) soil organic matter content (SOM) (2.80%), mean weight diameter (MWD) (2.56 mm), and water-stable aggregates content (WSA) (53.1%) compared to GCV. Ponding time (PT) and runoff time (RT) were lower on the TV which caused longer outflow time and increased total water runoff (WR) and sediment loss (SL). The TV had 745.4 times higher SL than GCV (TV 6.87 t/ha compared to GCV 0.0092 t/ha). Higher SL resulted in higher nutrient losses on TV. Tillage is recognized as unsustainable practice on the study area and a key factor for increased soil erodibility and potential environmental hazards by high nutrient losses.

“…The organic carbon content of the soil samples was determined by loss-on-ignition method (Schulte and Hopkins, 1996). Bulk density was determined with a core sampler (Tuffour et al, 2014). Soil organic carbon was then, converted to CO 2 by multiplying the fraction of SOC by the bulk density of the soil and the depth from which the samples were taken and, converted to tones per hectare.…”

Abstract. Soil aggregation is an important process in carbon sequestration and therefore a useful strategy to mitigate the increase in the concentration of atmospheric CO 2 . The study was, carried out on an Acrisol at the KNUST Cocoa (Theobroma cacao) plantation. Samples, covered with deep litter, shallow litter and no litter were taken from the 0 -15 cm depth from three different locations at the sampling site. The organic carbon content and aggregate stability were determined on air -dried samples sieved through graduated sieves into sizes of 0.5 -1.0 mm, 1.0 -2.0 mm, 2.0 -4.0 mm and 4.0 -6.0 mm using the loss-on-ignition method and modified wet-sieving method, respectively. The study showed that SOC sequestered was highest in the deep litter and the aggregate sizes of 4.0 -6.0 mm at all sites. The weighted mean of organic carbon for all sizes were 3.02% for deep litter, 2.84% for shallow litter and 1.55% for no litter spots, respectively. The aggregate sizes of 4.0 -6.0 mm also had the highest stability to external forces. There was also a positive correlation between SOC and aggregate stability. The study confirmed that mature cocoa farms have the potential to store more organic carbon and are relatively stable to reduce erosion and enhance root penetration.
