Relevant magnetic and soil parameters as potential indicators of the soil conservation status in Mediterranean agroecosystems
(Wiley, 2014-06)
The main sources of magnetic minerals in soils unaffected by anthropogenic pollution are iron oxides and hydroxides derived from parent materials through soil formation processes. Soil magnetic minerals can be used as ...
Characterization of potential CO2 emissions in agricultural areas using magnetic susceptibility
(Univ Sao Paolo, 2015-11-01)
Soil CO2 emissions (fCO(2)) in agricultural areas have been widely studied in global climate change research, but its characterization and quantification are restricted to small areas. Because spatial and time variability ...
Magnetic monitoring of anthropogenic pollution in Antarctic soils (Marambio Station) and the spatial-temporal changes over a decade
(Elsevier Science, 2021-08)
Marambio Station is one of the most important human settling in the Antarctic Peninsula, which has been polluted by human activities since the 1970s. Following the first magnetic monitoring in Antarctic soils (austral ...
Linking phosphorus sorption and magnetic susceptibility in clays and tropical soils
(CSIRO Publishing, 2020)
Protocol for the use of legacy data and magnetic signature on soil mapping of São Paulo Central West, Brazil
(2019-11-25)
The demand for information on the soil resource to support the establishment of public policies for land use and management has grown exponentially in the last years. However, there are still difficulties to the proper use ...
Do leaf-cutter ants Atta colombica obtain their magnetic sensors from soil?
How animals sense, process, and use magnetic information remains elusive. In insects, magnetic particles are candidates for a magnetic sensor. Recent studies suggest that the ant Pachycondyla marginata incorporates ...
Rock magnetism in soils of the Pampean plain. Buenos Aires province, Argentina. Linking climate and magnetic behaviour
(CENTRO GEOCIENCIAS UNAM, 2009)
Results of the study of Argiudolls in two localities (Zarate and Veronica) of the Pampean plain, Argentina, are presented in this contribution. This is a typical area covered by loess. The magnetic studies carried out ...
Magnetic and spectral signatures of Cerrado soils in the state of Goias, Brazil
(Empresa Brasil Pesq Agropec, 2017-10-01)
The objective of this work was to estimate the iron oxide contents (hematite and goethite) and to characterize the color and the spectral and magnetic signatures of Cerrado soils in the state of Goias, Brazil. Six Oxisols ...
