“…Thus, the compaction caused by animal grazing changes physical attributes through the repetitive and cumulative effects of trampling on soil (Capurro, Secco, Reichert, & Reinert, 2014). For this reason, porosity and the amount of water infiltration tend to decrease as the soil density and penetration resistance increases (Frolla, Aparicio, Costa, & Krüger, 2018). Thus, compacted soil can restrict plant root development (Ortigara et al, 2014) and diminish water infiltration (Miguel, Vieira, & Grego 2009).…”

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 general, the compaction caused by animal grazing alters physical attributes through the repetitive and cumulative effects of trampling (Capurro et al, 2014); thus, the amount of water infiltration tends to decrease as soil density and penetration resistance increase (Frolla et al, 2018). Such factors can delay the development of plant roots (Ortigara et al, 2014) by reducing water infiltration (Miguel et al, 2009) with lower production of pastures (Bonetti et al, 2015).…”

Integrated systems are conservationist and sustainable systems with great prominence on the national scene for reducing financial and productive risk in the agricultural sector and reducing environmental damage. One of the successes of these systems is to see the cultivation environment in an integrated way, knowing each of its components; soil, plant, and atmosphere. In large-scale field production, the plant and the soil are the components of the production system that are more likely to be modulated, seeking greater productivity. The objective of this work was to survey scientific advances on the chemical, physical and biological attributes of soil in integrated systems. The works show that chemical, physical and biological attributes are influenced by soil management in integrated systems. In general, integrated agricultural systems are more efficient alternatives for Brazil and must meet international commitments to reduce the greenhouse effect for low-carbon agriculture. For the rural producer, the integrated systems are advantageous due to the greater production in a smaller area and the diversification of income.

“…Whereas a considerable number of drivers are global, the current assemblage and interactions that bring about an ecosystem are more or less specific to a particular region or place. Although the influence on soil properties by higher-order plants [9,10] and animals [11,12] was well documented, a clear view on the potential influence of microbiota on soil properties is less profound. The reason is due to the difficulty of isolation and identification of species, for example., at moment only 1% of soil bacteria can be cultured.…”

Global change refers to anthropogenic and climate pattern modification. The consequences of these changes are outstanding on aboveground biodiversity. Soil microbiota are key actors in soil processes, contributing significantly to numerous ecosystem services provided by soil. They are involved in the processes of nutrient cycling, organic matter decomposition, or pollutants degradation. Microorganisms are also able to synthesize volatile organic compounds that are secondary metabolites with multiple ecological roles and mechanisms of action—generally contributing to plant development. Changes in soil microbiota community could modify either negatively or positively their contribution in soil-provided ecosystem services through their involvement in soil functions that they mediate.
