Evaluación de sedimento de vino de mora y su uso en la elaboración de compost en la Empresa Alma Natura de la Ciudad de Riobamba

Abstract

The sediment of blackberry wine of the company Alma Natura for its use in composting was evaluated. The investigation began with a preliminary physical, chemical and microbiological characterization of sediment of blackberry wine, whose results allowed to identify that it was feasible to be used as inoculum of compost. Four formulations of compost with 5%, 10%, 15% and 0% of sediment was developed, according to the quantity generated by the company and there were constructed batteries of compost of each of them with three repetitions obtaining a whole of twelve batteries. The batteries of compost were monitored for a period of sixty days, considering the control parameters (temperature, pH, humidity, microbial load). The quality of the compost was evaluated according to organic matter, percentage of nitrogen, percentage of phosphorus, percentage of potassium and relationship carbon : nitrogen; a statistical analysis was realized with the Tukey-b test, with which it is concluded that there are no significant differences in terms of organic matters, percentage of nitrogen, phosphorus and potassium using different concentrations of sediment; about the relationship carbon : nitrogen there are significant differences with the use of sediment to 5% and 10%, showing a higher percentage; however, it is not within the optimal range of mature compost according to the Manual of Composting of the Farmer of FAO. It is recommended to use the concentration of sediment of 5% or 10% to accelerate degradation of organic matter.
