sulfur-cycling

2 articles

Sulfur cycling refers to the biological and chemical processes by which sulfur moves through ecosystems, including its uptake, assimilation, and release by living organisms and soil microbes. In plant science, sulfur is an essential macronutrient required for the synthesis of amino acids, proteins, and secondary metabolites, making its availability in the soil directly tied to plant growth and stress responses. Understanding how plants acquire and metabolize sulfur—and how microbial communities transform sulfur compounds in the rhizosphere—is critical for improving crop nutrition and soil health.
