Resumo: The objective of this research was to study the water quality variations in the municipalities of the microregion CatoIé do Rocha, PB, Brazil. One hundred and sixty water samples were collected at two occasions: the first in November 1980 (dry season); and the second in May 1981 (just after the rainy season). These samples were analysed and classified as to risks of salinity, sodicity, residual sodium carbonate and boron. The results showed that after the rains there was an increase of about 7,6% in the good quality water for irrigation (C1S1 and C2S1), and in 8% of the water samples the boron level was above 1.25 ppm. According to these results, it may be concluded that the irrigation water commonly found has good quality (CE < 750 µmhos/cm), and can be used for irrigation of the majority of soils and crops, with little probability of salinity and/or sodicity risks.

Foram efetuadas duas coletas de 160 amostras de água; a primeira foi feita no mês de novembro de 1980 (período seco), e a segunda, durante o mês de maio de 1981 (após o período chuvoso). As água foram analisadas e classificadas quanto ao perigo de salinidade, sodicidade, carbonato de sódio residual e boro. Os resultados mostraram que após as chuvas, houve um aumento de 7,6% nas classes de boa qualidade (C1S1 e C2S1) e que 8% das amostras apresentaram teor de boto acima de 1.25 ppm. De uma maneira geral, de acordo com os fatores levantados, conclui-se que as águas estudadas são de boa qualidade (CE < 750 µmhos/cm), podendo ser utilizadas para irrigação da maioria dos solos e culturas, com pouca probabilidade de ocasionar risco de salinidade e/ou sodicidade.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCosta, Rubens GermanoGheyi, Hans Raj2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16016Pesquisa Agropecuaria Brasileira; v.19, n.8, ago. 1984; 1021-1025Pesquisa Agropecuária Brasileira; v.19, n.8, ago. 1984; 1021-10251678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16016/10163info:eu-repo/semantics/openAccess2014-04-16T19:26:20Zoai:ojs.seer.sct.embrapa.br:article/16016Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T19:26:20Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
