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 ...
Elasto-Plastic Behaviour of Soil Aggregates and the Soil Matrix as a Function of Physical Properties in three Soils of Central Chile
(Catena Verlag, 2013)
This study assessed the elasto-plastic behaviour of soil aggregates and of the soil
matrix in three soils of central Chile in terms of their structural development,
clay content and internal tension. Soil samples (cores ...
Fine roots of Prosopis flexuosa trees in the field. Plant and soil variables that control their growth and depth distribution
(Springer, 2018-12-15)
Fine root growth in natural vegetation is difficult to predict due to its regulation by soil and plant factors. Field studies in arid ecosystems show a variety of root responses to soil resources and to plant aboveground ...
Mudança do uso da terra e tipo de solo são fatores determinantes de fungos e arqueas no bioma pampa
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Ciência do Solo, 2012-02-29)
Land-use change and soil type can have significant impact on microbial communities of soil.
The Pampa biome in recent decades has undergone severe changes in landscape due to landuse
change, mainly for the introduction of ...
Below-ground carbon inputs contribute more than above-ground inputs to soil carbon accrual in a bioenergy poplar plantation
(Springer, 2019-01)
Background and aims: Soil organic carbon (SOC) accrual is central to the discussion on active atmospheric CO2 removal strategies, but it requires a clear understanding of the mechanisms driving new SOC formation. SOC is ...
Alternative method for volumetric core removal in hardsetting soilsMétodo alternativo para a retirada de anéis volumétricos em solos coesos
(Universidade de São Paulo, 2005-09)
Due to the narrow window of ideal moisture conditions required for collecting undisturbed soil samples from hardsetting horizons in the field, this study compared the efficiency of an alternative method of soil core removal ...
Influence of Physical-Chemical Soil Parameters on Microbiota Composition and Diversity in a Deep Hyperarid Core of the Atacama Desert
(Frontiers Media S.A., 2022-02)
The extreme environmental conditions and lack of water on the soil surface in hyperarid deserts hamper microbial life, allowing only highly specialized microbial communities to the establish colonies and survive. Until ...
