Desenvolvimento e avaliação de mini-evaporímetros de baixo custo para o manejo da irrigação nas condições de Cassilândia/MS.

Abstract

The objectives of this project was development of a mini-evaporations meters model of low cost and small size, that makes possible irrigation handling. Hence, the proposal was the use of two different types of containers installed in two distinct heights for measuring daily evaporation. The choice of these containers was made depending on the availability of local deals, being chosen common aluminum recipients (flat cake tin and lunch boxes) with circular format. For each treatment was determined a mat equation for obtaining an esteemed reading of a Class A tank. The T2 treatment (diameter of 32 cm, installed at 100 cm of height) was that most came close to the readings of evaporation of a Class A tank.
