Evaluación de diferentes volúmenes con riego tecnificado para la obtención de lexiviados de lombricompost a base de estiércol de cuy en San Isidro de Columbe

Abstract

In Ecuador there is little information on the incorporation of technician irrigation methods to evaluate different volumes of water to obtain vermicompost leachates from guinea pig manure at the local level. The general aim of this research was to evaluate the different volumes of water with technified irrigation to obtain guinea pig manure-based vermicompost leachates in San Isidro de Columbe. The specific objectives were to determine the volumes of water required to obtain leachates in the vermicompost process. To evaluate the nutritional quality of the leachates obtained from vermicompost based on guinea pig manure and to analyze the cost benefit of leachates obtained from vermicompost based on guinea pig manure. For this purpose, a completely randomized block experimental design (DBCA) was used, where 3 volumes of water were evaluated with 3 replications (V1, V2, V3) with V1 being the required volume (volume 230.4 L - irrigation time of 3.29h), V2 volume required plus 25% (volume 288.4 L - irrigation time 4.11h) and V3 volume required -25% (volume 172.8 L - irrigation time 2.46h), irrigation was fractioned for the seven days of the week, and irrigated in the morning and afternoon. Experimental measurements of temperature, humidity and pH were carried out on the vermicompost. In the soil laboratory of the Facultad de Recursos Naturales, organic matter, pH, electrical conductivity, macro and microelements of the leachate were analyzed. Finally, the costbenefit of the treatments was analyzed. It was determined that the volume of water to obtain leachate in the vermicompost process was 230.4 liters, for which a time of 3.29 hours was applied, which were divided into seven days with a daily application of 28 minutes, 14 minutes in the morning and 14 minutes in the afternoon. The most representative treatment where the best quality of the leachate can be seen corresponds to Volume 1, where it was possible to identify that both N and K are superior, the pH is neutral, which assures the development of the great majority of microorganisms. A Benefit/Cost ratio of 1.16 was obtained, so it is concluded that the leachates of vermicompost based on guinea pig manure are economically profitable.
