Do water dynamics and land use in riparian areas change the spatial pattern of physical–mechanical properties of a Cambisol?
(2022-01-01)
Changes in land use in riverside ecosystems added to the flood and ebb regimes of rivers modify the spatial variability of the physical–mechanical attributes of soil, making it more susceptible to degradation processes, ...
Soil macrofauna under integrated crop-livestock systems in a Brazilian Cerrado Ferralsol.
(Pesquisa Agropecuária Brasileira, v. 44, n. 8, p. 1011-1020, ago. 2009., 2011)
Quantifying soil compaction in persimmon orchards using isum (Improved stock unearthing method) and core sampling methods
(2020-07-01)
Agricultural activities induce micro-topographical changes, soil compaction and structural changes due to soil cultivation, which directly affect ecosystem services. However, little is known about how these soil structural ...
Pore morphology reveals interaction of biological and physical processes for structure formation in soils of the semiarid Argentinean Pampa
(Elsevier, 2019-08-01)
In order to obtain baseline values for the evaluation of soil degradation, the biological and physical quality of petrocalcic Paleustolls, of the calcrete plains of the Semiarid Region Pampa of Argentina, soils under ...
Características químicas de um latossolo vermelho em recuperação sob plantio de Pinus spp
(2016-01-01)
For the recovery of a soil, it is necessary to select and to identify suitable species to new soil conditions and, quickly, accelerate the structuring and formation of more superficial horizons of the soil. The experiment ...

accompanied by many ...
Quantification of the soil physical quality of a tropical oxisol using the S index
(São Paulo - Escola Superior de Agricultura Luiz de Queiroz, 2008)
Soil physical quality is fundamental for the sustainability of agro ecosystems. Soil physical quality assessment must be developed using parameters that describe physical behavior. S, a new soil physical parameter has ...
