Determinación de nutrientes en sedimentos lacustres de la laguna de Yambo, provincia de Cotopaxi

Abstract

The current research determined the nutrients present in the lake sediments of Yambo lagoon, located in Chimborazo Province. Twenty-six samples were randomly collected with an approximate distance of 100 meters. The samples were treated, dried and sieved, then pH, color, organic matter, total organic carbon, phosphorus, texture, electrical conductivity, calcium, sodium, potassium, magnesium and nitrogen were analyzed in the laboratory for the water quality, belonging to the Science Faculty of Escuela Superior Politécnica de Chimborazo, this was carried out according to the methodology for each parameter. The results revealed that the determinant nutrients were P lower than K, lower than N, lower than Na, lower than Ca and lower than Mg; the cationic exchange capacity was acceptable to provide nutrients like clay sediments and clay loam, the macro and micro nutrients studied did not have any relationship with the dissolved oxygen present in the water of the lagoon; however, it was the opposite for organic matter and total organic carbon, since if one of them decreases, the other decreases in the same way and vice versa according to the data. Thus, it is recommended to carry out studies on phytoplankton in order to establish a relationship, since the sediments did not reflect a higher relevance.
