摘要：

AimsReduction of the nitrogen (N) footprint of agroecosystems is currently a hot topic in various research disciplines and fields. However, the effect of machine-planted rice with side-deep fertilization (MRSF) on N loss and footprint of double-cropping rice fields in Hunan is still unclear.MethodsWe established a field experiment in which we applied various N compositions (N 135/148.5-90/99 kg ha-1) to early-season rice (ESR) and late-season rice (LSR). The loss of different N forms during the whole growth period of double cropping rice was measured. The N footprint of double cropping rice in...
