“…El suelo utilizado se clasificó con buen nivel de fertilidad (entre fertilidad media y alta), sugiriendo que este suelo tiene la capacidad de sostener el crecimiento y la producción del brócoli en un segundo cultivo. Se ha documentado rápida mineralización de C e N, cuando los fertilizantes orgánicos se incorporan al suelo y hay humedad y temperatura adecuada (Diniz et al, 2016). En el presente estudio los abonos orgánicos fueron incorporados y mezclados en los primeros 20 cm de profundidad del suelo, hubo humedad en el suelo y alta temperatura durante el primer cultivo, por lo que, se presume rápida descomposición de los residuos orgánicos y rápida mineralización de los nutrientes.…”

Compost, bokashi y microorganismos eficientes (EM) son alternativas viables para la nutrición de los cultivos agrícolas producidos de forma orgánica. Su aplicación afecta al primer cultivo y a cultivos subsecuentes. El objetivo fue evaluar el efecto de compost, bokashi y EM en el crecimiento, producción de materia fresca y materia seca en dos cultivos de brócolis consecutivos. En el primer cultivo de brócoli se aplicó: 19 t ha-1 de compost (C19), 19 t ha-1 compost + EM 2% (C19+EM2), 15 t ha-1 compost + 2 t ha-1 de bokashi (15C+B2), EM 2% (EM2), 10 t ha-1 de bokashi (B10) y testigo sin fertilización (TSF). En el segundo cultivo de brócoli se evaluó el efecto residual de los tratamientos sin realizar ninguna fertilización adicional. Similar área de dosel se observó entre tratamientos en el primer y segundo cultivo de brócolis. Con C19, C19+EM2 y B10 se obtuvo mayor cantidad de materia seca en comparación con TSF. En el primer cultivo de brócoli, el tratamiento con mayor rendimiento fue C19+EM2. El efecto residual de los tratamientos fue mayor en B10 al promover mayor producción de materia fresca del tallo en comparación con EM y TSF. La fertilización orgánica no afectó el crecimiento de las plantas en el primer y segundo cultivo. Fertilización exclusiva de compost y bokashi, aplicado solo o en conjunto promueven mayor materia fresca que plantas no fertilizadas, en el primer cultivo. EM potencia el efecto del compost, pues su aplicación conjunta estimula mayor materia fresca y materia seca que plantas no fertilizadas, en el primer cultivo. En los suelos con fertilidad media o alta, el compost aplicado solo o en conjunto con bokashi o EM sólo tiene efecto a corto plazo, pues no promovió efecto residual en el segundo cultivo de brócoli.

Solid Waste Management in Rural Areas

In recent decades, projections involving population growth, changes in consumption paterns, modiications of the wastes produced, and a signiicant increase in resource extraction have caused concern in the scientiic world, in treatment companies, and in environmental and governmental agencies throughout the world, regarding the destination of the large volume of solid wastes generated, the relatively high contents of potentially toxic, carcinogenic and mutagenic substances and pathogenic microorganisms. Waste management has become very important to ensure elementary resources such as water, phosphorus, and food in the future. The recycling policy thus requires that wastes be classiied in terms of their appropriateness for new uses and also based on their origins and hazardousness of handling. These classiications are essential in order to allow a minimum of rationality in their new destinations. Currently, several studies have been performed to use solid wastes from human activities as soil conditioners and/or fertilizers for increasing crop productivity. Therefore, studies that monitor organic waste efects on agricultural soils deserve the atention of the international scientiic community, as it enables increases in the productivity of agricultural crops, iber, and biomass energy combined to reduce risks to human, plant, and animal health and environment.

“…Vásquez de Diaz and colleagues have indicated that the process of degradation of coffee pulp under natural conditions without handling, normally takes 5 to 9 months, time to reach the degree of maturity to perform biotransformation, mineralization or complete degradation of the coffee pulp (Vásquez de Díaz;Prada;Mondragon, 2010), similar to the time on other organic remains such as tree pruning Heck et al (2013). On the other hand, on a sewage sludge compost around 3 month tales to have a total organic carbon around nine times total nitrogen at around 650 masl (Diniz et al, 2016).…”

Pulp and mucilage constitute the most abundant by-products of the processing of coffee and inadequate handling produces high-rates of pollution. Considering that in nature there is a large variety of cellulolytic microorganisms which can intervene in the degradation of coffee pulp, the inclusion of a native microbial cellulolytic consortium was assessed. The sample for isolation consisted of coffee pulp and soil from a humid forest at more than 2,000 masl. Nutrient agar was used as a means of isolation for bacteria, and malt agar for fungi, supplemented with 50% soil extract and 1% carboxylmethylbcellulose. This achieved the isolation of 118 strains of bacteria and 114 of fungi. Cellulolytic activity was established using the filter paper test, assessing and selecting only those that presented higher glucose production, among them 12 strains of fungi and 11 strains of bacteria. To obtain the microbial consortium, randomized blends were performed for both fungi and bacteria, again assessing the production of glucose. The bacterial consortium was made up of Ochrobactrum pseudo grignonense, Paenibacillus lauruscon and Bacillus xiamenensis and the fungal consortium by Fusarium sp., Penicillum sp., Cylindrocarpon sp. The optimal treatment achieved a complete degradation of the pulp in 28 days, that would contribute to the recovery and conservation of the coffee ecosystem. The main interpretation was that a wet environment at more than 2,000 masl is still suitable for coffee composting but different bacterial and fungi consortia were found to support other recent work done with one type of consortium.
