Valoración de los residuos sólidos aprovechables de la granja avícola Dos Hermanos mediante la técnica de compostaje en el cantón Chambo.

Abstract

The aim of this research was the estimation of the solid usable waste from the poultry farm Dos Hermanos through the composing technique in Chambo town. In this investiga-tion, different levels of hen droppings (20, 40, 60, 80%) were used to elaborate the semi ripe compost which was subject of completely random experimentation. Having finished the composing process, samples of 200 g of each treatment were collected in order to car-ry out the physical, chemical, and sensorial analysis. With the income and remittance, the cost-benefit of each treatment was determined. The use of 80% of hen droppings resulted in: humidity (36.76%), total nitrogen (2.20 mg/L), total phosphate (3,65 mg/L), potassium (2.51 mg/L), organic fertilizer (22.35 mg/L), and the best cost-benefit rate of 1.81; since every dollar invested produced a profit of 81 cents. In conclusion, the treatment that showed the best nutritional content was the one that correspond to the mixture of 80% of hen droppings. It is recommendable to apply the greatest quantity of organic fertilizer (80% of hen droppings) to produce the semi ripe compost because the final product shows very good agronomic characteristics. Therefore, this will contribute with nutrients for the ground to growth the crops.
