Impact: The project investigated the microbiota of bacteria and fungi in the rhizome of sugarcane plants grown in Brown soil with plastogenic carbonate, using various fertility research treatments in the Palma Soriano region, Cuba. It was found that fungi may play a crucial role in sugarcane, as their composition and abundance showed significant variations based on the different treatments applied. Beneficial microorganisms like Bacillus (bacteria) and Mucoromycotina (fungus) were detected in both the microbiota and mycobiota, although they were present in low abundance. The results suggest that adjusting certain soil chemical parameters could enhance their presence, potentially promoting nitrogen and phosphorus incorporation in plants and improving yield. Additionally, the study proposes investigating the soil's respiratory activity as a biological indicator of its quality to further understand its dynamics.
