“The 3-year experiment in Yuanyang, Henan Province showed that soil organic carbon accumulation is an important factor in regulating nitrogen loss in farmland, and the comprehensive advantage of annual nitrogen application rate of 285 kg/hm2 is obvious. Meta analysis revealed that the soil carbon sequestration rate in cultivated land is exponentially positively correlated with N2O emissions and has a parabolic relationship with nitrogen leaching, providing a solution for the green and low-carbon development of agriculture.”
