The purpose of this work was to verify the effect of hidroretentive polymers on the physical and hydraulic properties of two porous media. The experiments were carried out at the Soil Physics Laboratory at the Federal University of Paraná from 03/18 to 10/30/97. The research was developed using a Belgium type of retentive polymer incorporated in two porous media with their different physico-chemical properties; a Dark Red Oxisol and Marine Quartzous sand. The polymers were applied as dried grains at […]
