Notes.
Data were upscaled to 1 ha based on the data collected from this experiment. US$1.0=6.756 Chinese Yuan. The outputs of wheat and maize were calculated at organic prices, respectively, $0.89/kg−1 and $0.59/kg−1. CK, RSMT, SBMT and CMT represent no organic fertilizer treatment, rapeseed meal treatment, soybean meal treatment and cattle manure treatment, respectively.
