Straw incorporation into soil increases carbon (C) sequestration but can induce priming effects (PE), the enhanced breakdown of soil organic matter. The direction and magnitude of PE and the consequences for the C balance induced by straw addition depend on nitrogen (N) availability and soil managem...
