Advances in optimising nitrogen-use efficiency in crop production Danya RumoreGlobally, the quantity of nitrogen (N) fertilizer applied to crops is growing rapidly as it replaces the shrinking contribution of soil organic N and meets the demand by higher yielding crops. On average, crops recover close to half the applied N, so its inefficient management is an increasing problem. Low nitrogen use efficiency (NUE) leads to accumulation of mineral N in the soil and thence to pollution of groundwater, streams, oceans and
