Fire and grazing in the Caldenal of Argentina: Effects on plant and soil carbon and nitrogen
(Elsevier Masson, 2007-09)
Fire and grazing can modulate feedbacks between pools of carbon and nitrogen of plant and soil, altering cycles of these elements in grassland ecosystems. The magnitude of these effects may be limited by climate and by ...
Soil macrofauna as an indicator of soil quality in an undisturbed riparian forest and recovering sites of different ages
(Elsevier B.V., 2013-09-01)
Large expanses of riparian vegetation have been destroyed in Brazil, and few studies have focused on biological indicators of soil quality in Brazilian riparian ecosystems. The aim of this study was to assess relationships ...
Long-term lime and phosphogypsum broadcast affects phosphorus cycling in a tropical Oxisol cultivated with soybean under no-till
(2021-01-01)
Broadcast application of lime or phosphogypsum to suppress aluminum (Al) in soils can influence chemistry and fate of phosphorus (P) in natural environments. However, the long-term effects of these amendments in organic P ...
Persulfate-soil washing: The green use of persulfate electrochemically generated with diamond electrodes for depolluting soils
(2021-08-15)
Soil washing (SW) is a water-based approach that promotes a chemical-physical extraction as well as a separation process to eliminate or transfer the pollutants from soil to a liquid. Extraction step is often performed by ...

The effects of land management (grazing intensity) vs. the effects of topography, soil properties, vegetation type, and climate on soil carbon concentration in Southern Patagonia
(Academic Press Ltd - Elsevier Science Ltd, 2016-08)
Grazing is an economically important activity in Southern Patagonia?s steppe and woodland ecosystems. In the past, emphasis has been on maximizing the provisioning capacity of these ecosystems with little concern for the ...
Bioaccumulation pattern of lanthanides in pteridophytes and magnoliophytes species from Atlantic Forest
(SPRINGERDORDRECHT, 2012)
The availability of chemical elements for plants is mainly dependent on the nature of the soil and characteristics of each species. The transfer factors of lanthanides from the soil to the tree leaves of the Atlantic Forest, ...
Crop profile method in the identification of transformations in soil attributes by agricultural use
(Univ Estadual LondrinaLondrinaBrasil, 2008)
Contribution of Soil Components on the Sorption of Chlorpyrifos
(Springer, 2016-12-23)
It is generally assumed that the sorption of a nonionic pesticide on soil depends mainly on the content of soil organic matter (SOM); however, there are other factors that can contribute to this process. The possible causes ...
