| Popis: | Since the implementation of the integrated project in pork meat production, the region of Alto Paranaiba (MG)faced a new sector restructuring, which resulted in the installation of several agribusiness companies. However,the region is experiencing a strong environmental impact caused by the accumulation of pig slurry and themisuse of technological mechanisms that attempt to correct and fertilize soils without proper accountability.Aware of the various environmental concerns on a global scale that have been highlighted in international environmentalconferences (e.g., Kyoto Protocol), transnational companies, in partnership with pork meat producersfrom the region, began to invest in anaerobic biodigesters, which allow to reduce the organic load by 96%, providingelectrical energy (biogas) and producing biofertilizer. From the results of research done by Embrapa, theapplication of biofertilizer on the coffee and corn plantation has brought gains in productivity and plague elimination.Analyzing the soil after application, has found harmful high chemical concentrations to the environment.Therefore, this article aims to analyze the positive and negative aspects. This article aims to analyze the use ofbiofertilizers in agricultural areas of the Alto Paranaiba (MG) region, specifically in the municipalities of Patosde Minas and Patrocinio. |
