Evaluación de diferentes volúmenes de agua con riego tecnificado para la obtención de lixiviados de lombricompost a base de estiércol de bovino en la pradera

Abstract

This research aimed to evaluate different volumes of water with technified irrigation to get vermicompost leachates from bovine manure. The investigation methodology used was an experimental design, in which the use of a completely randomized block design was proposed, and the evaluation was based on different amounts of water in three repetitive processes to generate a causal analysis to get the leachate. The results were obtained by means of functional analysis, analysis of variance and Tukey's test at 5%, when there was a significant difference among the treatments. As a result, it was determined that the volume of water for leachate production was 387.2 litres, with an application time of 3.99 h, fractioned for the seven days with a daily application of 34 minutes as follows 17 minutes in the morning and 17 minutes in the afternoon. However, in the analyses carried out on the substrate, no significant difference in temperature or pH was obtained, although there was a significant difference in the humidity of the substrate. Regarding the analysis of the leachate in stages one and two, significant effects were observed for pH, OM, EC, Nitrogen, Phosphorus, Potassium, and Iron, with a p-value > 0.01. It was concluded that, the benefit/cost ratio reached $1.19, treatment V2 is the most profitable with a leachate production of 1000m2 per litre, with a production cost of $20,231 and total income of $24,000. It is thus established that the project is economically profitable and viable in leachate production.
