Soil moisture evaluation over the Argentine Pampas using models, satellite estimations and in-situ measurements
(Elsevier Science, 2020-10)
Study region: The Pampas region is located in the central-east part of Argentina, and is one of the most productive agricultural regions of the world under rainfed conditions. Study focus: This study aims at examining how ...
Global distribution an characteristics of black soils
(FAO, 2022-11-05)
Although “black soils” is a term used in some national soil classifications, which is influenced by the national linguistic specifics, there has been no consistent definition for black soils at the global level. In the
WRB ...
Residual effects of superficial liming on tropical soil under no-tillage system
(Empresa Brasil Pesq Agropec, 2016-09-01)
The objective of this work was to evaluate the long-term effects of the surface application of lime on soil fertility and on the mineral nutrition and grain yield of soybean, and of black oat and sorghum in crop succession. ...
Experimental research on the effects of water application on greenhouse gas emissions from beef cattle feedlots
(2014-04-30)
The effect of water application (e.g., through rainfall or sprinkler system) on emissions of greenhouse gases (GHGs), such as nitrous oxide (N2O), methane (CH4), and carbon dioxide (CO2), from pen surfaces of open-lot beef ...
Assessing the reactive surface area of soils and the association of soil organic carbon with natural oxide nanoparticles using ferrihydrite as proxy
(2020-09-09)
Assessment of the surface reactivity of natural metal-(hydr)oxide nanoparticles is necessary for predicting ion adsorption phenomena in soils using surface complexation modeling. Here, we describe how the equilibrium ...
Temperatura e umidade de um solo franco arenoso cultivado com milho
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Ciência do Solo, 2010-03-01)
Water is a key factor for crop yields, and causes major fluctuations in productivity, especially for maize cultivated in southern Brazil. Mulching the soil surface, temperature and soil moisture are factors closely linked ...
New methods to quantify NH3 volatilization from fertilized surface soil with urea
(Sociedade Brasileira de Ciência do Solo, 2011-01-01)
Gaseous N losses from soil are considerable, resulting mostly from ammonia volatilization linked to agricultural activities such as pasture fertilization. The use of simple and accessible measurement methods of such losses ...
Bioremediation of a petroleum hydrocarbon-contaminated Antarctic soil: Optimization of a biostimulation strategy using response-surface methodology (RSM)
(Elsevier Science, 2015-11)
Bioremediation is a biotechnological approach to clean up contaminated soils. Among bioremediation strategies, biostimulation is a simple method which involves the modification of the soil physicochemical conditions in ...
Estudo da interação solo-muro em concreto convencional, com resíduo de construção e demolição (RCD) e alvenaria de pedra
(Universidade Católica de Pernambuco, 2006-03-28)
One of the main problems, in the Region Metropolitan of Recife (RMR), in the hillsides it is the disordered occupation, increasing the number of housings in risk areas. One of the solutions for the stabilization of the ...
