Resumo: Floating materials were tested in Class A evaporation pans for reducing evaporation tosses from free water surfaces. The covering materials consisted of impermeable disks of vermiculite covered with parafine and palm (Copernicia cerifera Mart.) wax; vitrified clay spheric balls; clay spheric balls without vitrification; and styrofoam disks rendered impermeable by a mixture of palm wax and melted parafine. Each of these treatments covered 80% of the exposed surface of the evaporation pan and controlled 54%, 60%, 50% e 61% of evaporation losses, respectively. These results clearly show that all these covers are viable in controlling evaporation losses.

As coberturas consistiram de discos impermeáveis compostos de vermiculita, parafina e cera de carnaúba (Copernicia cerifera Mart.); esferas de barro vitrificadas; esferas de barro não vitrificadas; e discos de isopor impregnados de uma mistura de cera de carnaúba mais parafina derretida. Cada tratamento cobriu 80% da superfície exposta do tanque, apresentando os seguintes resultados no controle das perdas: 54%, 60%, 50% e 61% respectivamente. A eficiência apresentada indicou que as coberturas empregadas poderão ser viáveis.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPorto, Everaldo RochaAmorim Neto, Malaquias da SilvaSilva, Daniel Delfino da2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/14638Pesquisa Agropecuaria Brasileira; v.21, n.1, jan. 1986; 1-7Pesquisa Agropecuária Brasileira; v.21, n.1, jan. 1986; 1-71678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/14638/8332info:eu-repo/semantics/openAccess2014-10-16T18:28:48Zoai:ojs.seer.sct.embrapa.br:article/14638Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-16T18:28:48Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
