XIII SBGFA - CARACTERIZAÇÃO LIMNOLÓGICA DO RESERVATÓRIO RODOLFO COSTA E SILVA – ITAARA/RS-BRASIL

Fabio Marcelo Breunig, Flavio Wachholz, Waterloo Pereira Filho [2011]

O Brasil, devido a sua extensão, apresenta muitos ambientes aquáticos como rios, lagos e represas. Neste contexto, o trabalho tem por objetivo caracterizar alguns parâmetros limnológicos medidos em um reservatório de clima subtropical na região sul do Brasil. A área de estudo selecionada foi o reservatório Rodolfo Costa e Silva. Através de inspeção de campo, foram medidos os seguintes parâmetr ...

SUBJECT: o trabalho tem por objetivo caracterizar alguns parâmetros limnológicos medidos em um reservatório de clima subtropical na região sul do brasil. a área de estudo selecionada foi o reservatório rodolfo costa e silva. através de inspeção de campo; devido a sua extensão; apresenta muitos ambientes aquáticos como rios; e no centro jusante do reservatório; os dados foram interpolados e analisados através de mapas. as medidas de tss mostraram uma maior concentração no setor norte do reservatório

Aquaculture in coastal areas grows rapidly. For fish ponds construction, soil is dug and used as material for the conformation of dikes, frequently originating the exposure of Acid Sulphate Soils (ASS) containing extreme acidity, a saturation percentage less than 50% and exchangeable aluminum higher than 5 Cmol+Kg-1. When ASS is exposed to air, iron pyrite (FeS2) oxidizes (FeSO4) and produces ...

This research was conducted to determine the effect of soil pH change followed by leaching with ground water on crop growth, yield and nutrient uptake of strawberry. Treatments were leaching with ground water (A), hydrated lime application of dissolved portion in 500 gㆍL-¹ solution followed by leaching (B), application of Al₂SO₄ solution with the concentration of 0.75 gㆍL-¹ followed by leachin ...

The potential acidity is important because it is used in the determination of base saturation and the estimation of lime requirement. The objective of this study was to establish a regression equation to estimate the potential acidity with the SMP-pH measured in water under agitation of the SMP equilibrium solution with soil samples from the Jequitinhonha Valley, Minas Gerais State, Brazil. Th ...

Local indicators are useful to identify environments. In the region of Viçosa, Gleysols with their typically gray color are not common, although waterlogged soils under the plant cover "taboa" (Thypha dominguensis) are found. Most of the soils with high water tables are covered by "taboa", while the gley characteristics are not pronounced, especially in soils with high iron contents. Since the ...

Twenty-three reindeer bulls, aged 2-3 years, fed during two winter months at the Vuolda reindeer research station in Arjeplog, Sweden, were used in the study. The first group of eight reindeer was moved from their feeding corral to a selection corral, captured by lasso and stunned with a captive bolt outside the selection corral. The second group of seven reindeer was moved to the selection co ...
