Abstract

Abstract

En 中文
• Increasing C loading decreased the soil organic C formation efficiency of digestate. • Increasing C loading increased marginal mineral-associated organic C formation. • Increasing C loading decreased marginal particulate organic C formation. • Microbial physiology, rather than C saturation, drove contrasting C pool responses. • C formation was positively associated with hydrolases and negatively with oxidases.
