Impact of Synthetic Fertilizers on Soil Health

Scientists have been conflicting over the impact of synthetic fertilizers on soil health. Proponents of synthetic fertilizers argue that they provide essential nutrients to plants, resulting in greater crop yields and increased food production. Critics, however, assert that the long-term use of synthetic fertilizers can degrade soil quality, leading to a decrease in microbial diversity and nutrient depletion over time. They warn that reliance on synthetic fertilizers can disrupt natural soil ecosystems.

Two studies were conducted: Study A supports the use of synthetic fertilizers, claiming increased yields in crops grown with these fertilizers; Study B highlights the environmental impact, detailing how fields treated with synthetic fertilizers showed lower microbial activity compared to fields treated with organic methods.

Based on the arguments presented, which conclusion is most supported by the studies?
