“…This silica increase can be attributed to the water runoff coming into the stream because of the road construction, which allows the rapid erosion of forest-acidified and impoverished soils resulting from the intensive cropping of Pinus radiata on the mountain slopes nearby (ITURRONDOBEITIA and SALOÑA, 1991). Similar acidification processes are well-known world-wide (DAMBRINE et al, 1998 ;NOBLE et al, 1999 ;LILIENFEIN et al, 2000).…”

After the disappearance of the native crayfish in many rivers in Biscay, Basque Country, Spain, the signal crayfish Pacifastacus leniusculus was introduced in the main fluvial stretches and several breeding populations have established. One of the most productive zones was the Cadagua River, where the population was established from 1989 (first introduction) to 1995. Starting from that year, a marked decrease in population was recorded downstream, and this fact is studied in relation to fluctuations in physical and chemical conditions caused by human perturbations in the fluvial corridor mainly caused by the construction of a road.

“…The acidity found in forest wells is usually associated with carbonic acid dissolution, rock weathering and litter decomposition over the forest floor, which yields organic acids. [25][26][27] In fact, Williams et al and Chaves et al studying intact forests in Central Amazonas and Rondônia, respectively, found more acidic pH values (4.7 and 5.2) than those observed in the Urupá basin. 15,16 In addition to the above mentioned factors influencing acidity in groundwater, in rural and urban areas, domestic and industrial sewage disposal and soil alteration through corrective products and fertilizers can also influence pH.…”

Groundwater quality comparison between rural farms and riparian wells in the western Amazon, Brazil

et al. 2011

Recebido em 28/10/09; aceito em 30/7/10; publicado na web em 17/11/10Groundwater quality of a riparian forest is compared to wells in surrounding rural areas at Urupá River basin. Groundwater types were calcium bicarbonated at left margin and sodium chloride at right, whereas riparian wells exhibited a combination of both (sodium bicarbonate). Groundwater was mostly solute-depleted with concentrations within permissible limits for human consumption, except for nitrate. Isotopic composition suggests that inorganic carbon in Urupá River is mostly supplied by runoff instead of riparian groundwater. Hence, large pasture areas in addition to narrow riparian forest width in this watershed may have an important contribution in the chemical composition of this river.

“…hondurensis em relação à mata nativa. Em Latossolo argiloso da região de Uberlândia, MG, verificou-se que o cultivo de Pinus caribaea, embora não tenha alterado o pH do solo, reduziu de 0,2 a 0,6 unidade o pH da solução extraída das amostras de terra da camada de 0,15 a 1,2 m, em comparação com a vegetação de Cerrado (LILIENFEIN et al, 2000). A acidificação do solo em áreas florestais pode ser relacionada com a lixiviação de bases ou pela absorção desses elementos pelas árvores, o que seria mais evidente em solos intemperizados, pobres em nutrientes e com baixo tamponamento.…”

RESUMO -O objetivo deste estudo foi avaliar teores de carbono orgânico e atributos químicos do solo em áreas localizadas em Campo Belo do Sul, SC, nos seguintes usos da terra: campo nativo (CN); floresta de pinus (Pinus taeda) com 12 anos (P12); floresta de pinus com 20 anos (P20); reflorestamento de araucária (Araucaria angustifolia) com 18 anos (A18); e mata nativa de araucária (MN). O solo foi amostrado de forma sistemática, com oito repetições, coletando-se as camadas de 0,0-0,05; 0,05-0,1; 0,1-0,2; e 0,2-0,4 m. Os reflorestamentos com pinus e araucária mantiveram os estoques de C orgânico na camada do solo de 0,0-0,4 m em níveis equivalentes aos de mata e campo, totalizando de 12,5 a 14,2 kg m -2 . A acidez do solo e os teores de P disponível foram maiores, na média das camadas analisadas, no tratamento P20. Entre os nutrientes, verificaram-se teores baixos a médios de P disponível e de K, Ca e Mg trocável.Palavras-chave: Acidez do solo, nutrientes e reflorestamento. ORGANIC CARBON AND SOIL CHEMICAL ATTRIBUTES IN FOREST AREAS ABSTRACT -The objective of this work was to evaluate organic carbon contents and soil chemical attributes in forest areas in Campo Belo do Sul, Santa Catarina, Brazil, with the following land use: native grassland (NG); 12-year-old loblolly pine (Pinus taeda) reforestation (P12); 20-year-old loblolly pine reforestation (P20); 18-year-old araucaria (Araucaria angustifolia) reforestation (A18); and native forest with araucaria (NF).
