Input of fertilizer-derived labelled n to soil organic matter during a growing season of maize in the field

Fertilizer N was applied as 15N-labelled ammonium nitrate to a maize crop grown under field conditions in north-western France. After labelled-N was supplied (in May), plant and soil samples (to 80 cm depth) were collected at the 10-leaf stage (in June), flowering (in August) and harvest (in October...
