Caracterización física y microbiológica de un suelo contaminado por residuos líquidos de café.

Abstract

Improper handling of the products generated in the process of coffee cultivation generates large-scale negative  impacts on the coffee ecosystem, affecting both soil and air and water. The two main products of coffee are  generated during the process and ecological benefits of the fruit are the pulp and mucilage. The stated goal in  this project is to characterize the physical and microbiological parameters of soil contaminated liquid waste  coffee for later electrokinetic bioremediation. The research project was conducted in the MaSBEK in La Hacienda  Majavita owned by the Free University in Socorro Santander located at an elevation of 1379 m above mean sea  level, with an average temperature of 24 oC, to E1091.338, N1207.603. Among the main results the  characteristics of the O and A strata, the bacteria count and physical characteristics of surface water were  found. It can be concluded that the horizon obtained a gravel content of 1.19% over the organic horizon, which  had absence of this material therefore can be said that the first horizon has a greater drain, lower porosity and  therefore a decreased ability to retain ions and the colonies present in each sample plantings were maintained  in a range of 1.5 to 3 CFU CFU. Although the pH did not show any variation, the sample No. 2 obtained no growth  of bacteria, which could be due to the dilution performed for planting, which was 1: 1,000,000.
