The research was based on the composting of plant material from artificial wetlands, launched in a pilot project of wastewater treatment for Quebrada Mi Padre de Jesus located around the School of Environment and Natural Resources of the University District Francisco José de Caldas, carried out in 2010. Taking into account that these vegetal residues, end their useful life in the wetlands and do not have any specific use, an alternative of the use of these residues was generated, in the production of compost or compost organic. The need arises to find a method that makes possible its remarkable reduction, transformation and use in such a way as to generate a positive impact in the environmental, economic, social and health areas. In this case the composting was used as a technique for the biodegradation of the vegetal residues of the species Water Buchón (Eichhornia crassipes), Buchón Cucharita (Limnobium laevigatum.) And Junco (Schoenoplectus californicus), transforming them into an organic fertilizer; Similarly, biodegraded plant residues from the market place, which were collected from the Paloquemao market square located in the city of Bogotá, using the same technique with the purpose of having a comparative point in the final quality of the fertilizers, with With respect to the stipulated in the norm NTC 5167 fourth update, referring to chemical, physical, and microbiological parameters with which the fertilizers generated from organic residues of animal and vegetal origin must fulfill.
