Abstract
La comunidad de Kerecaya (3700-4000 msnm) del municipio de Salinas de Garci Mendoza del altiplano Sur de Bolivia, pese a sus riesgos climáticos, el productor valora un suelo pobre para su subsistencia. Las parcelas de quinua presentan materia orgánica inferior a 093%, humedad del suelo menor a 12.9%, temperatura del suelo por debajo de 8.5 ºC y pH inferior a 8.0. Se estudió la población de hongos en tres tipos de suelos que fueron: sin labranza (puruma), tradicional y mecanizado. Las muestras húmedas del suelo se recolectaron a una profundidad de 6 a 25 cm al azar en zig-zag, estas fueron procesadas mediante el método de dilución seriado e inoculadas en placas con 0.5 mL y se evaluó las colonias por método UFC´s/g de suelo, el género de Penicillium spp., con mayor población de 65.1%, seguido por Aspergillus spp., con 24.1% y Trichoderma spp., con menor abundancia de 13.8% y la población promedio en UFC´s/g de suelo fue de 1035.4 en sin labranza (puruma), 959.7 en tradicional y 868.2 en el mecanizado y la mayor población se presentó en el mes de febrero de 1572.8 UFC´s/g de suelo. Con estos datos se requiere investigar otros parámetros que influyen en la comunidad microbiana en esta comunidad.
The Kerecaya community (3700-4000 msnm) of the municipality of Salinas of Garci Mendoza of the south altiplano of Bolivia, in spite of your climatics risks. The plots of quinoa present lower organic matter to 0.93%, humidity of the smaller earth to 12.9%, temperature of the earth for under 8.5 ºC and pH lower to 8.0. The population of funguses in three types it has studied of earths that went: without farm (without entropic intervention), traditional and mechanized. The humid samples of the earth were gathered to a depth of 6 to 25 cm at random in zig-zag, these to be prosecuted by means of the method of seriate dilution and inoculated in plates with 0.5 mL and it is evaluated the colonies for UFC´s/g of earth, the genre of Penicillium spp., with major population of 65.1%, followed for Aspergillus spp., with 24,1% and Trichoderma spp., with minor great quality of 13,8% and the population average in UFC´s/g of earth it went of 1035.4 in without farm (without entropic intervention), 959.7 in traditional and 868.2 in the mechanized and the major population was presented in the month of February 1572.8 UFC/g of earth. With this data, it is necessary to investigate other parameters that influence the microbial community in this community.
