Tag hinzufügen | Zusammenfassung: | The present investigation was carried out in the town of Pastocalle, Cotopaxi province with the objective of identifying bacterial communities and determining the functional groups associated with the rhizosphere of the branch onion (Allium fistulosum) at 3180 masl, for the different functional groups the methodology of (Bernal, 2019), where culture media were used such as: Nutrient Agar (Total Microbiota), Rose Bengal (Total Fungal Population), Ramos Callao Agar (Phosphorus solubilizers), King's B (Pseudomonas), Soil Extract Agar (Cellulite Bacteria), Watanabe (Nitrogen Fixers) and Casein Agar (Actinomycetes). To know the state of soil composition, a chemical and physical analysis was carried out in the INIAP laboratory. For each group, six repetitions were established in the organic and conventional soil, plus a blind control, where the number of colonies*gr 1 was established. With the data it was obtained that in this altitudinal floor of 3180 masl that the functional groups with the highest number of colonies present a total microbiota with 8.45*1012 colonies *gr-1 in the organic soil sample, the number of colonies presents fungi with 3.81*1012 colonies *gr-1 in the conventional soil sample, the number of colonies presents phosphorus-solubilizing bacteria with 7.86*1012 colonies *gr-1 in the conventional soil sample, the number of colonies presents actinomycetes with 3.79*1011 *gr-1 colonies in the organic soil sample, the number of colonies presents in pseudonyms with 4.09*1012 *gr-1 colonies in the organic soil sample. Following these values, the number of colonies in cellulotic bacteria presented low levels with 4.40*1012 colonies *gr-1 in the conventional soil sample and the number of colonies presented in nitrogen fixers with 4.09*1012 colonies *gr- 1 in the organic soil sample. These data can be corroborated with the soil analysis (INIAP) that presents an average average in the organic soil that there is more high microbial life with M.O. = 1.62%, and on the contrary the conventional soil with a low average O.M. =0.45 presenting a low microbial life. |
