Assessment and monitoring electric of conductivity well water used for irrigation in Salgueiro-PE region

Abstract

The municipality of Salgueiro is located in a semi-arid region of the state of Pernambuco, which is characterized by rainfall with irregular temporal and spatial distribution. In this region, irrigated agriculture appears as an
alternative for the economic sustainability of agricultural activity. Agriculture is one of the main economic activities of the municipality. The main agricultural products produced in the region are: onion, tomato, herbaceous cotton, corn, banana, beans, rice and mango. The problem of salinity in irrigated areas is aggravated when the salt balance reveals a higher entrance than exit, promoting an increase of the saline concentration in the area under consideration, conditions in which the irrigation water, besides contributing to the increase of the saline concentration, Provoke the elevation of the water table that, through ascending capillary, starts to supply water and salts to the root zone. Thus, this work aims to
evaluate and monitor the salinity of well water used for irrigation purposes in the city of Salgueiro-PE, through the analysis of the electrical conductivity. In addition, the project is also being applied in the rural communities of the region, where the farmer has a simple knowledge about the salinity of the wells that are mainly used in subsistence plantations.
