Influence of Urea and Ammonium Sulfate on Soil Acidity Indices in Lowland Rice Production
(TAYLOR & FRANCIS INC, 2010)
Urea and ammonium sulfate are principal nitrogen (N) sources for crop production. Two field experiments were conducted during three consecutive years to evaluate influence of urea and ammonium sulfate application on grain ...
EVOLUTION PATTERNS OF THE SOIL ORGANIC-MATTER IN SOME AGRICULTURAL SYSTEMS IN THE BRAZILIAN CERRADO REGION
(Gauthier-villars, 1993-01-01)
Several changes in the soil humus characteristics were observed after clearing the Central Brazil virgin forest. When compared with the original ''Cerrado'' forest, the soils from the agricultural systems showed increased ...
EVOLUTION PATTERNS OF THE SOIL ORGANIC-MATTER IN SOME AGRICULTURAL SYSTEMS IN THE BRAZILIAN CERRADO REGION
(Gauthier-villars, 1993-01-01)

Assessing the relations among the features of the land cover and of the soil on the soil-water interactions through a functional eco-hydrological indicator
(2019-09-01)
Soil Water Repellency (SWR) is an important ecological property that has implications in the soil and water management and is a useful functional eco-hydrological indicator driven by several natural and human factors. In ...
Modulation of the soil microbiome by long-term Ca-based soil amendments boosts soil organic carbon and physicochemical quality in a tropical no-till crop rotation system
(2021-05-01)
Unsustainable agricultural management practices such as non-conservationist tillage and overuse of fertilizers result in soil acidity and, in turn, soil degradation due to reduced carbon (C) concentrations and nutrient ...
Soil P Diffusion and Availability Modified by Controlled-Release P Fertilizers
(Springer, 2020-11-24)
Slow-release fertilizers have been proposed as tools to increase P fertilizer use efficiency in tropical acidic soils with high P adsorption, low P availability, and mobility. However, results have been controversial since ...
Soil acidity in the Argentine Pampas: Effects of land use and management
(Elsevier Science, 2020-02)
Soil acidification restricts crop yield in many regions. Our objective was to estimate what effect land use has had on soil acidity in the Pampean Region of Argentina. Sampling paired sites under contrasting land uses ...
Catabolic response and phospholipid fatty acid profiles as microbial tools to assess soil functioning
(2016-12)
Microbial properties may help to provide an integrated view of changes in soil functioning associated with soil management or soil status. The fatty acid profiles of membrane phospholipids (PLFA) can give the composition ...
Characterization and application of the solid waste generated in the production of calcium carbonate precipitate as a corrective for the soil acidity
(ESCOLA DE MINAS, 2010)
The calcium carbonate industry generates solid waste products which, because of their high alkaline content (CaO, CaCO(3) and Ca (OH)(2)), have a substantial impact on the environment. The objectives of this study are to ...
Chemical changes in an oxisol treated with pyroligneous acid
(Universidade Federal de Lavras (UFLA), 2014-03-01)
The use of pyroligneous acid (PA), a by-product of charcoal production, is an ancient practice applied in agriculture to control soil and plant pests and diseases. However, little is known about the chemical alterations ...
