Cocompostaje de residuos vegetales provenientes de la Finca Agropecuaria La Inmaculada con estiércol de cuy, vaca y gallinaza.

Abstract

The present research work was carried out in the agricultural farm "LA INMACULADA" located in Guano Canton province of Chimborazo: where organic solid waste of vegetal origin is generated causing pollution. The object of this investigation was to recycle the organic solid waste generated in the aforementioned farm through the composting technique to develop an organic fertilizer that can be used as soil amendment. The initial characterization of the materials to be composted was carried out adjusting an adequate C / N ratio (between 25-30) humidity and particle size to ensure an adequate composting process. Subsequently, 3 one ton batteries with dimensions were elaborated dimensions (2 meters high, 3 wide and 2 long) by windrow system, which were P1 (vegetable waste + chicken), P2 (vegetable waste + guinea pig dung) and P3 (vegetable waste + manure cow) in proportions of 76% and 24% for plant residues and residues of animal origin respectively. The PH, humidity and temperature are monitored as the main control parameters of the process, registering 5 turns during the same with a total of 21 samples collected in which analyzed physical-chemical, chemical and biological parameters such as: pH, EC,% MO, Corg, Nr, C / N ratio, soluble polyphenols and IG to determine the evolution of the process, while for the characterization of the final compos was determined the CIC, content of macro, micronutrients and heavy metals. In general, the results showed alkaline pH values, CE within the range, high MO% in relation to the degree of stability, all the compost showed C / N values, CEC suitable for a mature compost, while the micro and macronutrients and heavy metals they presented adequate contents, all the compost being obtained from class A, which is therefore suitable for agricultural use.
