Elementos interferentes na qualidade da água para irrigação

Abstract

For the development of agriculture in the world, water is a natural resource of greater relevance, since new technologies to increase productivity of agricultural areas are dependent on their availability. This importance is reflected in the high productivity of irrigated areas, where only 18% of the total agricultural areas account for approximately 40% of global agricultural production. The objective of this study was, by means of a literature review, evaluate and discuss some of the main types of water used and attributes that can affect the quality of water for irrigation. It was concluded that the use of lower quality water, such as wastewater or stillage, is an alternative to meet the high demand for water in relation to low supply. But for this, one must have a knowledge of the main attributes that pose interfere with the quality of water for irrigation, and the degree of hazard to health and the environment.
