Cambios químicos en los recursos hídricos causados por lixiviados de hidroponía en una finca de flores en la sabana occidente de Bogotá

Abstract

The quality of groundwater and surface water is affected by human activities, including agriculture and livestock. These two activities require applications of both organic and inorganic fertilizers, which by different processes end up in the waters making the quality of these are lower, however, today the guilds of growers and agricultural producers encourage the use of good agricultural practices and livestock in order to be certified and thus expand their markets. Within the good practices of the floricultural sector, evaluations of qualities in the used waters (microbiological and physicochemical) are made, but it does not focus on the impacts that these activities may cause in the waters of natural bodies. The parameters that were evaluated in the study to determine if there is contamination to nearby sources are: pH (potential of Hydrogen), Electrical Conductivity, Free Chlorine, Nitrates and Nitrites; These samples were taken along the path that the hydroponics leachate has, identifying 3 key points: the leachate from the hydroponics container, an external watterway to the greenhouse and finally, at the point where the hydroponics waters meet together with the wetland waters .
