Maize stover biochar increases urea ( 15 N isotope) retention in soils but does not promote its acquisition by plants during a 4-year pot experiment

ABSTRACT Biochar as a soil amendment has been shown to improve soil quality and crop growth. However, biochar’s effect on urea-N use efficiency in long term is not well elucidated. Here we studied urea-N (15N isotope) allocation in plants and soil in the presence of maize (Zea mays L.) sto...
