EFICACIA DEL INÓCULO ENCAPSULADO EN PROCESO DE COMPOSTAJE DE RESIDUOS AGROPECUARIOS

The objective of this research was to evaluate the efficacy of the microbial inoculum encapsulated in composting piles of agricultural waste. The piles were prepared with a mixture of 100 kg of laying hen manure and 200 kg of peanut shell, the inoculum variants were: T1 (200 g of capsules), T2 (400 g of capsules), T3 (600 g of capsules) and a control (without inoculum). During the composting process, the physical, chemical and biological parameters of the substrate were analyzed. As a result, it was obtained that all the piles showed temperatures above 55°C. The pH value in the inoculum piles was slightly alkaline in the range of 7.6 to 8.2, while the EC values ranged from 1.03 to 1.58 dS m-1. On the other hand, the moisture content ranged between 55 and 60%. Treatments T2 and T3 presented the highest % organic matter, macronutrient content and germination index, unlike T2 presented the highest content of Fe and Mn. It is concluded that the treatments with the addition of the microbial inoculum presented physical, chemical and category A phytotoxicity indicators.
