O ESTADO DA ARTE DA IRRIGAÇÃO POR GOTEJAMENTO SUBSUPERFICIAL

Abstract

There is a growing interest for the subsurface drip irrigation system due to the need for new technologies that present larger water application efficiency and allow the wastewater reuse. This kind of system allows to increase both, the plant production and the nutrient use efficiency, but it was not completely researched in full detail , despite there are thousands of hectares irrigated by that kind of system all over the world. The bibliographic references show a predominance of the system use in tomato crop, and Brazil is one of the countries rethe matter . Cotton is another crop in which subsurface drip irrigation systems are largely used, with a wide research in the United States. This kind of system is also highlighted for wastwater reuse,because it avoids the wastewater contact with plants and humans. It is being applied in the irrigation of grasslands of the United States, Canada and Europe. The main objective is to characterize and to describe the state of the art of the subsurface drip irrigation systems all over the world, trying to show its current use in agriculture, and also its advantages and disadvantages.
