Resumen:
The forage legume Lotus tenuis is an appealing alternative to meet the needs for cattle production in the Flooding Pampa region, Argentina. The use of chemical compounds for agriculture practices, in addition to the removal of native vegetation, eventually may change the diversity of soil microbial components such as bacterial and fungal communities. To examine the effect of L. tenuis promotion with herbicides on the structure of soil bacetrial as well as fungal communities , we studied three different rangeland sites of the Flooding Pampa region. At each site, two paddocks were compared: one managed to promote the forage legume L. tenuis, and the other lacking of management history and hence, covered by natural grasses we applied 454-FLX pyrosequencing technology of the V4 region of the 16S rRNA gene (bacteria) and also the internal transcribed spacer región ITS1-ITS2 (Fungi), on genomic DNA extracted from soil samples. Our results suggest a differential response between communities: while 5-6 years of land use with L. tenuis promotion modify the structure of soil fungal community, we did not find differences among treatments when soil bacterial communities were analyzed.
