Efeitos da infiltração no desempenho da irrigação por sulco simulada em solo franco-arenoso.

Abstract

The effect of a sand-loam soil infiltration characteristics upon the furrow rrigation system performance was verified through field evaluations and a sensitivity analysis, using the SIRMOD model. It was verified that an increase in the soil infiltration capacity from 0.094 to 0.168m3/m , promoted an increase in the deep percolation losses up to 47.8%, and a decrease equal to 20.2% in the runoff, resulting in a degeneration of the application efficiency from 60.5% to 32.9%.
