Caracterización físico-química y microbiologica del estiercol de vicuña para la producción de fertilizantes orgánicos

Abstract

he vicuña is a species that determines its range by producing dunghills. However, the waste of the benefits of manure can cause an imbalance in the ecosystem due to the lack of control of this organic waste. Therefore, this work aims to characterize the physical-chemical and microbiological properties of vicuña manure for producing organic fertilizers. Vicuña manure samples were collected in two strategic areas of the Chimborazo de Bolívar Fauna Production Reserve belonging to San Juan and Tungurahua corresponding to Carihuairazo, which were subjected to physical-chemical analysis through the evaluation of pH, electrical conductivity (EC), organic matter and color. The microbiological analysis determined the presence of microorganisms, including bacteria, actinomycetes, and fungi; with the help of laboratory techniques, the development of root growth of radish (Raphanus sativus) and kidney tomato (Solanum lycopersicum) seeds was evaluated in the statistical analysis used in the hypothesis tests for independent samples to compare the results of the manure characteristics between the two sampling areas (Tungurahua and Bolívar). With the help of InfoStaf statistical software, the Shapiro-Wilks normality test is performed. If the data is normally distributed, the Student's t-test is applied. For data not conforming to a normal distribution, Wilcoxon is used for independent samples. This work determines that the microorganisms promoting the growth of the seedlings were bacteria, resulting in more excellent stem and root length in the evaluated seedlings. It concludes that the samples collected from vicuña manure from the Chimborazo Fauna Production Reserve presented physical, chemical, and microbiological characteristics suitable for producing organic fertilizers.
