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 ...
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 ...
Numerical simulation of cation exchange in fine coarse seawater slurry pipeline flow
(Elsevier, 2018)
Slurry pipelines transporting a coarse—the comminution product—and a fine fraction, both in the presence of
seawater, can cause an alteration of the liquid phase chemical composition. In the present paper, we present ...
Analytical procedure based on slurry sampling for determining selenium in organic vegetable samples by graphite furnace atomic absorption spectrometry
(Springer, 2009-07-01)
This paper presents a simple, fast and sensitive method to determine selenium in vegetable samples by graphite furnace atomic absorption spectrometry through the direct introduction of slurries of the samples into the ...
Determination of vanadium in human hair slurries by electrothermal atomic absorption spectrometry
(Elsevier B.V., 2007-02-28)
This work describes an analytical procedure for vanadium determination in human hair slurries by electrothermal AAS using longitudinal heating (LHGA) and transversal heating (THGA) graphite furnace atomizers. The samples ...

Dinâmica da produção de forragem e proteína bruta do capim bermuda sob adubação mineral e orgânica
(Universidade Federal de Santa MariaBrasilZootecniaUFSMPrograma de Pós-Graduação em ZootecniaCentro de Ciências Rurais, 2020-03-27)
Chemical fertilizers are the most crucial inputs for enhancing yield of cultived pastures.
The use of organic fertilizers can contribute to reduce there costs and make the productive
systems more sustainable. This study ...
