Impacts of Long-Term Inorganic and Organic Fertilization on Lignin in a Mollisol

Fertilization is an essential management method to maintain and increase soil organic carbon (SOC) content in agroecosystems. Fertilizer application is known to markedly influence the turnover of labile and refractory SOC components. However, the dynamics of lignin in response to different types of fertilization remains unclear. This study addresses the impact of long-term fertilization on lignin accumulation in an arable soil.
