El estudio consistió en la elaboración de composta a partir de cachaza subproducto de la caña de azúcar (Saccharum officinarum L.). El diseño experimental consistió en cuatro tratamientos: cachaza + 0.4%, 0.6% y 0.8% de urea mas un testigo (cachaza sin urea), con tres repeticiones, el modelo estadistico fue completamente . Durante el tiempo de composteo se analizaron las características fisico-químicas (pH, temperatura, humedad, relación C/N)y microbiológicas (coliformes totales y fecales, bacterias mesófilas y termófilas aerobias y Salmonella). Adicionalmente se evaluó el rendimiento de la composta. Los resultados indican que ocho semanas de composteo son suficientes para obtener una composta estable desde el punto de vista fisico- químico y microbiológico. EI tratamiento 2 (0.4% urea) presentó la mejor relación C/N con 51.29, sin embargo, no hubo diferencias significativas (α=0.05). No se detectó Salmonella en las compostas y el rendimiento fue de 53.91% en promedio para los tratamientos analizados.
This study consist in compost elaboration of cane mud (filter cake), sub product ofsugar cane (Saccharum officinarum L.), Experimental had four treatments: cane mud (filter cake) plus 0.4%, 0.6% and 0.8% urea and one witness (cane mud filter cake without urea), with three repetitions. Statistical model was completely at random. During the composting time physic-chemical characteristics were analyzed:(pH, temperature, moist content, C/N ratio) and microbiological(total and fecal coliforms, mesophilic and thermophilic aerobic bacteria and Salmonella) Efficiency of compost was not evaluated. Results show that eight weeks composting were sufficient to obtain physic-chemical and microbiological stable compost. Treatment 2 (0.4% urea) show the best C/N ratio of 51.29, however, there was significative differences (α=0.05). Salmonella was not detected in compost and eficiency was 53.91% average for the analyzed treatments
