“…Regarding the compost, the three main elements considered for the growth of the microorganism (N, P y K), are present below the levels reported by Álvarez-Solís et al (2010), N= 0.095%, P= 0.65% and K= 0.83%. These results show that in those composts where trash collection from DF and vegetable waste are included, there is a decrease in the content of those nutrients (Castillo et al, 2000). The organic matter content (OMC), considered an important source of nutrients (Pérez et al, 2010), was 27.36%, which is a good amount for compost.…”

Evaluación de compost con presencia de metales pesados en el crecimiento de Azospirillum brasilense y Glomus intraradices* Evaluation of compost with presence of heavy metals on the growth of Azospirillum brasilense and Glomus intraradices ResumenCompost es materia orgánica que resulta de la acción microbiana controlada en residuos orgánicos. Hoy en día, la agricultura es responsable del uso integrado de biofertilizantes y compost, que representan una alternativa importante para reducir el uso de fertilizantes químicos. En este estudio se evaluó el compost con presencia de metales pesados sobre el crecimiento de A. brasilense y G. intraradices. El análisis microbiológico del compost solo mostro resultados significativos para el crecimiento de S. aureus y P. aeruginosa. La conclusión es que el uso de compost con presencia de metales pesados no causa ningún efecto adverso sobre el crecimiento de A. brasilense y G. intraradices, ya que los dos microorganismos pudieron ser aislados e identificados en la rizosfera de la planta. Por otra parte, los metales no excedieron los límites máximos permitidos por las normas internacionales como la NTC-5167 y la norma 503 de EPA.Palabras clave: A. brasilense, G. intraradices, composta, metales pesados. AbstractCompost is an organic material obtained as a result of the controlled microbial action on organic waste. Nowadays, farming is responsible of the integrated use of biofertilizers and compost, which represent an important alternative to reduce the use of chemical fertilizers. In this study the compost with presence of heavy metals on the growth of A. brasilense and G. intraradices was evaluated. Microbiological analysis of compost only revealed significant results for the growth of S. aureus and P. aeruginosa. The conclusion is that the use of compost with presence of heavy metals does not cause any adverse effects on the growth of A. brasilense and G. intraradices, since the two microorganisms were able to be isolated and identify in the rhizosphere of plants. Furthermore, observed metals did not exceed the maximum permissible limits by the international standards as NTC-5167 and standard 503 of EPA.

“…Castillo et al (2002) observed total-N concentration of 1.25% in vermicompost obtained from bovine manure and means from 1.02 to 1.11% in mixtures of bovine manure + food remainders, while Barbados (2003) pointed out that the optimum interval for a vermicomposting process product is 1.0 to 2.6%, as seen in the four treatments under study. Melgarejo et al (1997) suggest an N content higher than 2% to allow the organic fertilizer for continuing its humification and mineralization process in the soil.…”

“…Initially, the mixtures were subjected to a 15-day pre-composting process to avoid possible damage to earthworms due to a temperature increase (Castillo et al, 2002). Later on, ten adult Red Californian Earthworms (Eisenia fetida) per liter per experimental unit were inoculated (Hernández et al, 2002).…”

The forestry-livestock waste materials represent a serious ecological problem if they are not handled properly in agricultural activities. Vermicomposting is a biotechnological process with potential to transform such materials into products that can be safely used as soil enhancers. The objective of this study was to evaluate the nutritional characteristics of organic fertilizers obtained from forestry-livestock organic waste materials when they are processed through vermicomposting using "Red Californian Earthworm" (Eisenia fetida). A completely randomized experimental design with four treatments and eight replicates was performed. Treatments (mixtures) included: leaf litter + sawdust (LS), bovine manure + sawdust (BS), rabbit manure + sawdust (RS), and ovine manure + sawdust (OS). Total nitrogen, pH, carbon/nitrogen ratio, organic carbon and nitrates from vermicompost samples were measured and statistically analyzed using SAS v8.2. At the end of the study, all mixtures showed similar characteristics according to the analyzed variables. Carbon/nitrogen ratios decreased in three mixtures to values considered as within the vermicompost maturity stage. Contents of nitrates and total nitrogen were www.ccsenet.org/sar

“…Letra mayúscula en común y en una misma fila no son significativamente diferentes (p≤0,05 (C/N) alta que indicaría una mineralización más lenta (Castillo et al, 2000) como sucede en los sustratos FC+CPC y CPC+FC (en Frankenia) que tienen menos nitrógeno total y la MO más alta. Estos valores dependerán en muchas ocasiones de la naturaleza de las mezclas empleadas.…”
