How does stainless steel affect soil microorganism activity?
Stainless steel, widely used in construction, agriculture, and industry, can influence soil microorganism activity in several ways. When stainless steel particles or corroded fragments enter the soil, they release trace metals like chromium and nickel, which may alter microbial communities. Some studies suggest that low concentrations of these metals can inhibit enzyme production and metabolic functions in beneficial bacteria and fungi, reducing nutrient cycling efficiency. However, certain resistant microbes may adapt, leading to shifts in soil biodiversity. Long-term exposure to stainless steel residues could disrupt soil health, affecting plant growth and ecosystem balance. Further research is needed to assess the ecological risks and mitigation strategies.
