Deep soils modify environmental consequences of increased nitrogen fertilizer use in intensifying Amazon agriculture
Deep soils modify environmental consequences of increased nitrogen fertilizer use in intensifying Amazon agriculture
Intensively-managed croplands and nitrogen (N) fertilizer use are expanding rapidly in tropical regions. We quantified fertilizer responses of maize yield, N2O emissions, and N leaching in an Amazon soybeanmaize double-cropping system on deep, highly-weathered soils in Mato Grosso, Brazil.
