Resumo: | The classification of water for irrigation purposes is usually based only on their individual levels ions or in its total salinity according to the electrical conductivity. Meanwhile, a classification that takes into account the relevance of each ion in solution in the electrical conductivity of the water, better explains the origin of its salinity. From physical-chemical characteristics of water tubular wells in the region of Janaúba and Jaíba, North of the state of Minas Gerais, was carried out a study of classification of the irrigation water and analysis of the contribution of ionic composition in total salinity, using multiple linear regression with selection for step by Stepwise method. Based on the average levels of Ca, Mg, and Cl the water of the region of Janaúba and Jaíba is indicated for use in irrigation, from using alternative management. The levels of Na in water alone do not offer risks of sodicidade. But the levels of HCO3 in the water higher than Ca and Mg, may interfere with the relationship of sodium adsorption. The water of the region is classified as a medium to high risk of salinization of the soil and can be used whenever there is a moderate degree of leaching and adequate drainage. Despite high levels of HCO3 in the water, the levels of Ca, Mg and Cl contribute in larger proportions in increasing the total salinity. The average values of osmotic potential estimated are an indicative of the need for use adequate of irrigation water. |

Entretanto, uma classificação que leve em consideração a relevância da condutividade elétrica de cada íon da água, esclarece melhor a origem de sua salinidade. A partir de características físico-químicas da água de poços tubulares da região de Janaúba e Jaíba, Norte do Estado de Minas Gerais, realizou-se um estudo de classificação da água de irrigação e analise da contribuição de sua composição iônica na salinidade total, utilizando a regressão linear múltipla, com seleção por etapa pelo método Stepwise. Com base nos teores médios de Ca, Mg, Na e Cl a água da região de Janaúba e Jaíba é indicada para irrigação, desde que utilizem alternativas de manejo. Os teores de Na na água por si só não oferecem riscos de sodicidade. Mas, os teores de HCO3 na água superiores aos de Ca e Mg, pode interferir na relação de adsorção de sódio. A água da região é classificada como de médio a alto risco de salinização dos solos, podendo ser usada sempre que houver um grau moderado de lixiviação e drenagem adequada. Apesar dos elevados teores de HCO3 na água, os teores de Ca, Mg e Cl contribuem em maiores proporções no incremento da salinidade total. Os valores de potencial osmótico estimados são um indicativo da necessidade de uso adequado da água de irrigação.Universidade Federal de Viçosa - UFV2010-06-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/10210.13083/reveng.v18i3.114Engineering in Agriculture; Vol. 18 No. 3 (2010); 208-218Revista Engenharia na Agricultura - REVENG; v. 18 n. 3 (2010); 208-2182175-68131414-398410.13083/reveng.v18i3reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/102/84Ribeiro, Moisés SantiagoLima, Luiz AntônioFaria, Fábio Henrique de Souzados Santos, Silvânio RodriguesKobayashi, Mauro Kojiinfo:eu-repo/semantics/openAccess2023-01-19T12:49:46Zoai:ojs.periodicos.ufv.br:article/102Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T12:49:46Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false |
