- DISMINUCIÓN DE LA EVAPORACIÓN DEL AGUA DESDE SUPERFICIES LIBRES UTILIZANDO COMO RETARDADOR EL ALCOHOL ESTEARÍLICO R. Polón L. Alfonso M. A. Ramírez O. Ledea J. M. Dell´Amico D. Morales R. Morejón Agrociencias water losses alcohols Evaporation The experiment was developed under semicontrolled conditions in Los Palacios Rice Research Station for three years (2005-2007) ap plying a randomized complete experimental design, two treatments and five replicates. The study consisted of using a water evaporation retardant (stearilic alcohol) making a monolayer on the free water surface, which prevented big water losses by evaporation; the treatment with retardant reduced losses up to 14.97 mg.min-1 .cm-2, whereas the treatment without it reached the biggest water losses: 30.27 mg.min-1.cm-2; thus, the retardant is very effective, since its application proved to reduce significantly water losses. 2009 artículo científico 1819-4087 https://www.redalyc.org/articulo.oa?id=193217899015 es http://www.redalyc.org/revista.oa?id=1932 Cultivos Tropicales application/pdf Instituto Nacional de Ciencias Agrícolas Cultivos Tropicales (Cuba) Num.1 Vol.30
