Assessing biogeochemical effects and best management practice for a wheat–maize cropping system using the DNDC model [PDF]
, 2014 Contemporary agriculture is shifting from a single-goal to a multi-goal strategy, which in turn requires choosing best management practice (BMP) based on an assessment of the biogeochemical effects of management alternatives.
