| description |
Cyanobacteria have the property of reducing atmospheric nitrogen through the process known as Biological Nitrogen Fixation. The objective of the work was to evaluate the potential use as biofertilizer of a consortium of nitrogen-fixing cyanobacteria adapted to the agricultural soils of the Province of Córdoba in the cultivation of Zea mays L. First, the isolation and obtaining of massive cultures of consortiums of edaphic cyanobacteria, from selected agricultural soils of the Province of Córdoba, which were made up of the following species: Scytonema bonheri, Nostoc commune, N. edaphicum. N. muscorum, N. calcícola and Desmonostoc muscorum. From these consortia, liquid emulsions were prepared to be applied to crops. The controlled trials in cultures of Zea mays L. were carried out considering three treatments: with chemical fertilization, with a consortium of cyanobacteria and with chemical fertilization and a consortium of cyanobacteria. The results obtained, when considering the development variables, show that there are no significant differences between the treatments with chemical fertilization and with the cyanobacterial consortium used. In relation to the soil fertility conditions at the end of the trial, the maximum values of nitrate and phosphorus were obtained in the treatment with cyanobacteria consortia. The cyanobacterial community at the end of the trial conserved 3 of the 6 species that made up the initial consortium, all of the genus Nostoc. These results will make it possible to advance in the knowledge about the potential of cyanobacteria as agricultural soil improvers and their use as biofertilizers to achieve productive yields similar to those obtained by the aplication of chemical fertilizers. |

Las cianobacterias tienen la propiedad de reducir el nitrógeno atmosférico a través del proceso conocido como fijación biológica de nitrógeno. El objetivo del trabajo fue evaluar el potencial uso como biofertilizante de un consorcio de cianobacterias fijadoras de nitrógeno adaptadas a los suelos agrícola de la Provincia de Córdoba en el cultivo de Zea mays L. Para lo cual, se realizó el aislamiento y obtención de cultivos masivos de consorcios de cianobacterias edáficas, a partir de suelos agrícolas de la Provincia de Córdoba seleccionados, los cuales se conformaron con las siguientes especies: Scytonema bonheri, Nostoc commune, N. edaficum. N. muscorum, N. calcícola y Desmonostoc muscorum. A partir de estos consorcios se prepararon emulsiones líquidas para ser aplicados en los cultivos. Los ensayos controlados en cultivos de Zea mays L. se realizaron considerando tres tratamientos: con fertilización química, con consorcio de cianobacterias y con fertilización química y consorcio de cianobacterias. Los resultados obtenidos, al considerar las variables de desarrollo, muestran que no hay diferencias significativas entre los tratamientos con fertilización química y con el consorcio de cianobacterias utilizado. En relación a las condiciones de fertilidad del suelo al final del ensayo, los máximos valores de nitrato y fósforo se obtuvieron en el tratamiento con consorcios de cianobacterias. La comunidad de cianobacterias al final del ensayo conservó 3 de las 6 especies que conformaron el consorcio inicial, todas del género Nostoc. Estos resultados, permitirán avanzar en el conocimiento sobre el potencial de las cianobacterias como mejoradoras de suelo agrícolas y su utilización como biofertilizantes para alcanzar rendimientos productivos similares a los obtenidos por la aplicación de fertilizantes químicos.
