Soil erodibility assessment in a pasture and forest remnant using the inderbitzen device
(2013-05-28)
Brazil has the largest cattle herd in the world with approximately 200 million head. An important feature of the Brazilian cattle industry is that most of its herd is raised on pasture, which constitutes one of the most ...

Spatial Variability of Soil Organic Matter and Cation Exchange Capacity in an Oxisol under Different Land Uses
(2016-12-30)
Soil properties may exhibit large spatial variability. Frequently this variability is auto-correlated at a certain scale. In addition to soil-forming factors, soil management, land cover, and agricultural system may affect ...
Pedotransfer function to estimate the soil structural S index and spatial variability in an Oxisol within a livestock farming system
(2020-01-01)
Various attributes are often required to build soil quality indicators. However, determining these attributes is time-consuming and requires several specific devices. Thus, it is desirable to develop indexes that express ...
Alterações na estrutura do solo e anisotropia dos poros sob pisoteio animal e tráfego de maquinário
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilPrograma de Pós-Graduação em AgronomiaUTFPR, 2018-05-30)
The use of heavy farm machinery and excessive animal trampling can exert a lot of pressure on the ground. When this pressure exceeds the ability of the soil to resist for the modification of the soil structure, which often ...
Multivariate approach of soil attributes on the characterization of land use in the southern Brazilian Amazon
(2018-12-01)
Determination of physical, chemical and biological attributes with individual analyses is inadequate for improving the understanding of soil conditions as a function of land-use change (LUC) in comparison to the natural ...
Soil stabilisation by water repellency under no-till management for soils with contrasting mineralogy and carbon quality
(Elsevier, 2019-08-23)
No-till soil management is common around the globe, but the impacts on soil structural quality varies depending on cropping practice and inherent soil properties. This study explored water repellency as a driver of soil ...
Replacement of native vegetation alters the soil microbial structure in the Pampa biome

Visual soil structure quality assessment on Oxisols under no-tillage system
(São Paulo - Escola Superior de Agricultura Luiz de Queiroz, 2010)
Methods for evaluation the soil structure quality based on field evaluations are useful to determine strategies for soil management, with the advantage of requirement the use of little equipment and the possibility of ...
