Soil microorganisms play a vital role in the regulation of the transformation and cycle of soil nutrients, thereby improving soil fertility and crop productivity. These microbes, associated with plants, contribute significantly to plant growth and development by improving nutrient cycling and crop productivity by improving soil fertility. This systematic review aims to assess the impact of microbial activity on nutrient cycle and transformation, which includes soil fertility and crop productivity improvement. The PRISMA flow methodology systematically included articles from various geographic regions. Through analyzing 120 articles, this review sought to address the question at hand. Among the articles analyzed, 31.4% indicate that soil microbial activity directly regulates nutrient cycling, while 68.6% suggest that microbial activity enhances soil fertility and crop productivity. The systematic review concludes that microbial activity has a significant effect on nutrient cycle and transformation, as well as on improving soil fertility and crop productivity. Farmers, policymakers, and experts are encouraged to manage soil microorganisms to regulate nutrient cycling, directly influencing soil fertility and crop productivity, thus promoting sustainable agricultural development.
