Uniformidade de distribuição de água na superfície e no perfil do solo, irrigado com o microaspersor RAIN-BIRD QN-14.

Abstract

In the field, it was evaluated the uniformity coefficient of distribution of water at the surface and in the soil profile at the depths of 0-0.20; 0.20-0.40; and 0.40-0.60 m, getting at the respective depths the coefficients of 64.90%, 79.04% and 84.06 % and the surface, a mean coefficient of 42.61%. It can be noted that the uniformity in soil profile increase with the depth due to lateral redistribution of the water.
