Monitoring water quality for irrigation from underground water supply sources in the upper basin of the Almendares-Vento source
Main Article Content
Abstract
out a monitor the water quality for irrigation from groundwater
supply sources located in the upper part of the birth of the
Almendares-Vento basin. A network was established for the
realization of monitor composed of 12 wells; two are located in
the Central Area of the Instituto Nacional de Ciencias Agrícolas
(INCA), four in the INCA Agricultural Services Department,
and six in farms of producers belonging to two CCS
strengthening of San José de las Lajas city ANAP. To
implement an appropriate sampling strategy, wells were
classified according to their intensity of exploitation according
to the area and crops under irrigation. It was proposed a
methodology for water sampling for analysis. The values of
the evaluated indicators compared with different classifications
for the water quality for irrigation. As main results found that
the waters quality of the studied wells, turned out good
according to the classifications discussed. Therefore, they may
be used without restriction for use in agricultural irrigation. He
demonstrated according to the French degrees Hidrotimétricos
waters of different wells in study were hard and very hard,
important aspect to take into account for irrigation systems
maintenance. The Confidence Interval analysis of indicators
Electrical Conductivity (CE), Total Dissolved Salts (SDT),
sodium absorption ratio (RAS), pH and calcium content in
high exploitation wells, allow to considerably decreasing the
frequency of sampling.
