摘要

The wastewater has been an environmental problem, but your used as fertilizers could reduce or eliminate the application of commercial fertilizers in soil. Arbuscular mycorrhizal fungi (AMF) and nitrogen fixing bacteria (NFB) are a good parameter to analyze the impacts of this fertigationon soil. We aimed to evaluate the distribution and diversity of AMF and NFB before and after applications of wastewater or manure from green line of a cattle slaughterhouse in the irrigation of B. brizantha cv Marandu in Cerrado soil and leaf biomass productivity. The experimental design was performed in completely randomized blocks with ten biofertigation managements. The seeds of the forage were distributed in grooves with spacing of 5 cm. This seeds were covered with a soil layer. NFB and AMF diversity was performed by denaturing gradient gel electrophoresis (DGGE). The leaf biomass productivity in the biofertigation managements was higher than in the managements without the use wastewater/manure. After biofertigation managements, changes in the DGGE profile of the NFB and AMF communities were observed. These changes may be due to the difference in the sample collection period and in the soil humidification. Thus, these DGGE profiles was a good parameter to diagnose the efficacy of wastewater/manure as an alternative biotechnological irrigation.
