Co-compostaje de residuos del café provenientes de la parroquia sinaí-morona santiago.

Abstract

The “Parroquia Sinaí” does not have an adequate final disposal for coffee residues which are piled up in the collection center and deposited directly on agricultural soils or coffee plantations. The objective of the current research work was to develop a co-composting to take advantage of these sub products; taking into account the implementation of field methodology with a mixed approach which started with the collection of waste by using windrow piles performed with a ton of coffee residues and manure assembling three treatments: The first with a ratio of 50% residues 50% cow manure, the second with a ratio of 60% residues 40% cow manure and the third with a ratio of 70% residues 30% cow manure. The piles were assembled with a layer of coffee residues followed by a layer of manure until completing the ton between treatments, and the size of each pile was 1m wide x 2m long. The physical-chemical characterization showed that the humidity of the pulp was 72% and husk 24%, the electrical conductivity was 3.69 dS/cm and 1.04 dS/cm, the percentage of organic matter was 78.76% and 65.25%, the pH was 4.13 and 4.73, assimilable potassium was 2.04 % and 0.57 %, available phosphorus was 59.65ppm and 165.37ppm in the chemical analysis of the treatments, the carbon-nitrogen ratio should be higher than 20/1 and lower than 30/1, where only treatment 1 complied with a value of 26.30. The treatment 1 can be used as compost by the coffee growers of Sinai, while the two treatments can be evaluated to stabilize them. Finally, it is recommended to carry out co-composting with facultative microorganisms to obtain it in fewer weeks.
