Biotransformações do nitrogênio no solo durante a decomposição de palha de trigo e dejetos líquidos de suínos
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Ciência do Solo, 2007-04-20)
Nitrogen is usually the element present in higher concentration in pig slurry and the one that causes the major problems related to environmental pollution, since it is subjected of several transformations after soil slurry ...
Copper and zinc forms in soil fertilized with pig slurry in the bean crop
(Univ Federal Campina Grande, 2016-09-01)
The application of pig slurry may have different influence on copper (Cu) and zinc (Zn) dynamics in the soil compared with mineral fertilization. The aim of this research was to determine the different forms of Cu and Zn ...
Microbiological activity and N transformations in a soil subjected to aggregate extraction amended with pig slurry
(Inst Investigaciones Agropecuarias, 2015)
Pig slurry as a fertilizer source has been extensively used in agriculture; however, in order to reduce the risks of contaminating the water supplies given its high level of N sources, it is important to understand the N ...
Transformações do carbono e do nitrogênio no solo e produção de aveia com o uso de dejetos de suínos em plantio direto
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Ciência do Solo, 2005-08-12)
The use of pig manure, especially of the deep-bedding manure, is not so often in the winter cover crops, preceding the summer commercial plantation. The aim of this study was to evaluate the carbon and nitrogen dynamics ...
Emissão de óxido nitroso e dióxido de carbono após aplicação de dejetos de suínos e bovinos em um argissolo
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Ciência do Solo, 2009-03-02)
Emission of greenhouse effect gases due to the agricultural use of the dejections of animals as fertilizers, as well as the mineralization of the carbon of those materials in the soil healthy aspects are still relatively ...
Enhanced lindane removal from soil slurry by immobilized Streptomyces consortium
(Elsevier, 2014-05)
Lindane is a chlorinated insecticide which was used worldwide. Nowadays its persistence, bioaccumulation and toxicity are well known. One of the strategies for its elimination is bioremediation. For this purpose, the use ...
Dejetos líquidos de suínos afetam a decomposição de palha de aveia?
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Ciência do Solo, 2010-08-21)
In no-tillage system the application of animal wastes is made on the soil surface, without incorporation. As such, a common practice is the application of the wastes on oat residues which vary in their C/N ratio, depending ...
Mitigation of N2O emissions from grassland by nitrification inhibitor and actilith F2 applied with fertilizer and cattle slurry
(2002-06-24)
Nitrous oxide (N2O) is involved in both ozone destruction and global warming. In agricultural soils it is produced by nitrification and denitrification mainly after fertilization. Nitrification inhibitors have been proposed ...

(2002-06-24)
Nitrous oxide (N2O) is involved in both ozone destruction and global warming. In agricultural soils it is produced by nitrification and denitrification mainly after fertilization. Nitrification inhibitors have been proposed ...
How do greenhouse gas emissions vary with biofertilizer type and soil temperature and moisture in a tropical grassland?
(Science Press, 2020-10-01)
Greenhouse gases are known to play an important role in global warming. In this study, we determined the effects of selected soil and climate variables on nitrous oxide (N2O), methane (CH4), and carbon dioxide (CO2) emissions ...
