Resumo: The objective of this work was to determine the measurement accuracy of the soil water matric potential (ψm) by puncture tensiometers with either rounded or pointed porous cups, installed with or without “soil mud”, and to compare the performance of these tensiometers with that of tensiometers equipped with mercury manometers. The experiment was conducted in a Ultisol, in a randomized complete block design, in a factorial arrangement with five replicates. Puncture tensiometers with rounded porous cups, installed with “soil mud”, present more elevated accuracy for ψm determination in a wider measurement range, resembling tensiometers equipped with mercury manometers in drying soil.

O experimento foi conduzido em Argissolo Vermelho-Amarelo distrófico, em delineamento experimental de blocos ao acaso, em arranjo fatorial, com cinco repetições. Tensiômetros de punção com cápsulas arredondadas, instalados com “lama de solo”, apresentam maior acurácia nas determinações do ψm em uma faixa mais ampla de medidas, assemelhando-se aos tensiômetros com manômetros de mercúrio com o secamento do solo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCoordenação de Aperfeiçoamento de Pessoal de Nível Superior - CapesFranco, Hélio Henrique SoaresSilva, Alvaro Pires daTormena, Cássio AntonioFerreira, Camila Jorge BernabéNunes, Márcio RenatoLima, Renato Paiva deLibardi, Paulo Leonel2017-12-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/25064Pesquisa Agropecuaria Brasileira; v.52, n.12, dez. 2017; 1291-1294Pesquisa Agropecuária Brasileira; v.52, n.12, dez. 2017; 1291-12941678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/25064/14053https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/25064/16872https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/25064/16873Direitos autorais 2017 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2017-12-21T10:21:52Zoai:ojs.seer.sct.embrapa.br:article/25064Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2017-12-21T10:21:52Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
