“…Similar patterns were verified by Lima et al (2018) who also observed an increase in Bd in a cultivated area, when compared to an area of native forest. For Milagres et al (2018), the increase in Bd is related to the decrease in soil organic matter content. This inverse correlation between Ds and organic matter content was also observed in this study, since the highest Bd values were quantified in the anthropized area, in which the lowest levels of organic matter were quantified.…”

The anthropization of natural environments, when performed inadequately, promotes the disruption of the ecological balance and can influence the fauna, flora and biodiversity in general, including the edaphic environment and its components. The objective was to evaluate the soil attributes in areas with different types of vegetation cover and different forms of soil management. The study was carried out in native forest area (Subperennial Equatorial Forest) and cultivated area (annual species), in Porto Velho, Rondônia, Brazil. Samples were collected in two layers (0-10 and 10-20cm), on a Latossolo Vermelho-Amarelo, to evaluate microbial biomass by the fumigation-extraction (FE) method, as well as the chemical and physical soil attributes. It was possible to verify a significant increase in soil density and reduction of moisture and improvement of chemical attributes resulting from the use of the area. The organic matter content decreased sharply in the managed area (25%), compared to the forest, in the superficial layer (0-10cm). Microbial C-biomass under the native forest showed 54% higher mean value (883 mgC g-1) compared to the managed area (410 mgC g-1) in the superficial layer. The microbial N-biomass ranged from 21.3 to 19.5 mgN.g-1 in the native forest area, and from 9.3 to 11.5 mgN g-1 in the managed area, respectively in the 0-10 and 10-20cm layers. In the native forest area, the addition of organic matter to the soil by the vegetation litter was an important conditioning factor for the microbial community, demonstrating the use of this attribute as an indicator of soil quality.

“…Among the decompaction forms employed is the use of subsoilers and/or scarifiers, implements capable of breaking compacted soil layers in the subsurface. However, its effects tend to disappear in up to 24 months (Drescher et al, 2016;Milagres et al, 2018).…”

The objective of this work was to qualify the improvement of the physical properties of the soil and the reduction of weeds by combining the management of the superficial cover associated with a strategy of physical improvement soil in the drilling, seeking the maintenance of the no-tillage system. The experiment was carried out in the 2015/16 and 2017/18 harvests, using a randomized block design in a two-factorial scheme (3 2) with three managements of the ground cover (chopped, rolled and natural) and two depths of planter's shank (7 and 12 cm). Counts and identification of weeds emerged in the row and between the lines of the soybean crop at 20 and 40 days after emergence, bulk density, mechanical resistance of the soil to penetration and total soil porosity in the flowering of the soybean culture were measured. The management of the straw cover combined with the depth of action of the planter shank influenced the emergence of weeds, as well as, the increase in the depth of the furrow improvement of the physical environment of the soil in the sowing line, reducing penetration resistance, bulk density and increasing total porosity.

“…The soil has both vertical and horizontal heterogeneity, depending on the nature of the factors responsible for its formation. Studies report that the variability of soil physical properties showed correlation or spatial dependence (GUIMARÃES et al, 2016;MILAGRES et al, 2018). The attributes soil density, texture, structure, porosity, soil penetration resistance, litter and soil organic matter have been used as indicators for soil quality measurement.…”

The monitoring of soil attributes allows the evaluation of its ability to perform its functions within an agroecosystem. The objective of this work was to evaluate the spatial variability of soil physical attributes, litter and carbon stock in a family farming system in the Cerrado Tocantinense. The area is located in the southern region in the state in the municipality of Aliança do Tocantins. Four types of land use were diagnosed in the area: brachiaria pasture intercropped with stylosanthes, Andropogon pasture, orchard and native forest. The native forest was considered as a reference. The study area totaled 7.9 ha-1 in which it was distributed an irregular sample grid composed of 160 points. Deformed and undeformed samples were collected for each georeferenced point at depths of 0-10 and 10-20 cm, as well as samples to determine the litter and soil carbon stock. Data were submitted to exploratory analysis and geostatistical study. It was found that the conversion of native forest for different soil uses through orchard, brachiaria, andropogon and native forest caused spatial variability in physical attributes, litter and soil carbon stock at depths 0-10 and 10-20 cm. The orchard subarea stood out as a promising system in the accumulation of organic carbon due to cattle manure.
