Influence of a tropical grass (Brachiaria brizantha cv. Mulato) as cover crop on soil biochemical properties in a degraded agricultural soil
(Elsevier France-editions Scientifiques Medicales Elsevier, 2017-11)
The inclusion of tropical grass forage as a cover crop (CC) could be a useful tool to improve microbiological activity and, consequently, soil quality. The aim of this study was to evaluate the effect of Brachiaria brizantha ...
Biochemical and biological properties of soil from murundus wetlands converted into agricultural systems
(Sociedade Brasileira de Ciência do Solo, 2019-02)
The implementation of conservationist systems that improve soil properties and reduce the impacts of the conversion of native areas is fundamental for feasible agricultural exploitation. This study aimed to evaluate the ...
SPATIAL VARIABILITY AND SAMPLING DENSITY OF MAGNETIC SUSCEPTIBILITY AND SOIL PROPERTIES IN ULTISOLS OF THE MANICORE REGION, AM, BRAZIL
(Soc Brasileira De Ciencia Do Solo, 2015-05-01)
The difficulty in finding recent information on the spatial behavior of properties of soils in the Brazilian Amazon region has been a concern of many researchers. Due to the great difficulty and costs in assessing soil ...
Land-use change affects the diversity and functionality of soil bacterial communities in semi-arid Chaco region, Argentina
(Elsevier, 2022-04)
The semi-arid Chaco ecoregion has been heavily affected by the conversion of pastures to cropland. Our knowledge about the impact of land use change on soil microbial community diversity and functions in this region is ...
Effect of iEucalyptus globullus/i biochar addition on the availability of phosphorus in acidic soil
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias Agrarias, 2017-01-01)
Phosphorus (P) is one of the primary nutrients limiting crop production. The application of phosphate fertilizers in acidic soils leads to the formation of secondary insoluble compounds that reduces the effectiveness of ...
Intensive annual crop production and root development in a tropical acid soil under long-term no-till and soil-amendment management
(2018-01-01)
In tropical conservation agricultural systems, crop yield is limited by soil acidity and root-growth inhibition, especially under intensive crop rotation. This study evaluated the effect of surface applications of lime and ...
Impact of land use on Histosols properties in urban agriculture ecosystems of Rio de Janeiro, Brazil
(Sociedade Brasileira de Ciência do Solo, 2022)
Microbial indicators of soil health as tools for ecological risk assessment of a metal contaminated site in Brazil
(2012)
Microbial and biochemical indicators of soil health were used to assess the ecological conditions and biological activity of soils contaminated with metals at a lead smelter plant and surrounding area in northeast Brazil. ...
Specific depth cone resistivity measurements to determine soil engineering properties
(2003-03-01)
The University of British Columbia (UBC) began performing piezocone penetration tests (CPTU) with electrical resistivity measurements (RCPTU) in 1989. Since then, RCPTU research at UBC has focused on obtaining geo-environmental ...
