Biological activity of soils cultivated with yacón (Smallanthus sonchifolius Poep. & Endl) H. Robinson, inoculated with Azospirillum brasilense and native mycorrhizal fungi

The soil is influenced by the roots of plants because exudate radicals affect its physical, chemical, and biological processes. aim this research was to evaluate microbial activity soils cultivated with yacón (Smallanthus sonchifolius Poep. & Endl) H. Robinson inoculated microorganisms which promote plant growth. experimental design used randomized blocks three repetitions per treatment. Each repetition corresponded a 3m x plot 25 plants, in 5 cultivation lines distance 70 cm apart. Four treatments were applied at time plantation. These consisted propagules Azospirillum brasilense (T1) native mycorrhizal fungi (T2) consortium (T3). In control treatments, not these (T0). Soil samples collected lots located Province Catamarca, northwest Argentina. implantation harvest during agricultural cycles. total Biological Activity (TBA) determined Fluorescein Diacetate Hydrolysis. TBA affected different crop rose analyzed statistically from treatments. Significant differences also observed between beginning crops comparison recorded values harvest. inoculation A. affects marking significant increase.
