    cultivated in Tungurahua, Ecuador, highlighting its critical role in soil health and agricultural sustainability. Understanding the composition and functionality of microbial communities in the rhizosphere is essential for developing efficient agricultural practices and enhancing crop resilience to environmental stressors. This research provides foundational insights for future studies exploring the potential of these microbial communities to improve soil fertility and agricultural productivity under specific agroecological conditions. Samples were collected from six representative localities and analyzed using bioinformatics tools such as QIIME 2, EzBiocloud, and PICRUSt to assess microbial diversity and predict functional profiles. Proteobacteria was identified as the dominant phylum, followed by Actinobacteria and Acidobacteria. The highest microbial richness was observed in La Florida and Chiquicha Chico, with Chao1 values surpassing four thousand, whereas Yacupamba exhibited lower diversity due to acidic soils and low organic matter levels. Key metabolic pathways such as nitrogen fixation and antimicrobial compound synthesis were identified, with notable microorganisms including A. xylosoxidans and A. calcoaceticus. Although statistical differences were not significant, the results are highly relevant for generating hypotheses about the relationship between microbial composition and soil health. Expanding the scope of this study with larger sample sizes and integrating advanced techniques like functional metagenomics and metabolomics could facilitate the development of specific biofertilizers and sustainable agricultural strategies, ultimately enhancing crop resilience and productivity under changing environmental conditions.
