Resumo: Ion input via rainfall alone and after interception by the forest canopy, constitutes an important path of biochemical cycling, although few studies have provided information on the subject so far. The objective of this work is to quantify ion inputs, via rainfall, in the southwestern region of Rio Grande do Sul state, Brazil. Ten rain gauges were mounted in a field area. The quantification of stored water volume, along with sample collection for determination of nitrate, nitrite, ammonium, phosphorus, sulfur, chlorine, calcium, magnesium, potassium and sodium contents, was done fortnightly from September 2006 to August 2008. Local annual average precipitation in the relevant period was 1,588.3 mm. The concentration of chemical elements in rainwater was found to vary throughout, being inversely correlated with the increase in rainfall, while potassium, ammonium, phosphate, sulfate, chloride and sodium were found to have a significant mutual correlation (p <0.01). Based on the annual amount of nutrient input via rainwater, it can be inferred that rainfall is an important source of chemical element input into the forest system.

Objetivouse, neste estudo, quantificar a entrada de íons, via precipitação pluviométrica, na região Nordeste do Rio Grande do Sul, Brasil. Em uma área de campo, instalou-se 10 pluviômetros. A quantificação do volume de água armazenado, bem como a coleta de amostras para determinação de nitrato, nitrito, amônio, fósforo, enxofre, cloro, cálcio, magnésio, potássio e sódio foram realizadas quinzenalmente de setembro de 2006 a agosto de 2008. A precipitação média anual ocorrida no período foi de 1.588,3 mm. A concentração dos elementos químicos na água da chuva apresentou-se variável durante o período de estudo, com correlação inversa ao aumento da pluviosidade, sendo que o potássio, amônio, fosfato, sulfato, cloreto e sódio apresentaram correlação significativa mútua (p < 0,01). Com base na quantidade anual de aporte de nutrientes pela água da chuva, pode-se inferir que a pluviosidade é uma importante fonte de entrada de elementos químicos no sistema.Universidade Federal de Lavras (UFLA)2015-05-142017-08-01T20:13:46Z2017-08-01T20:13:46Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfCALIL, F.
