Promoting rice growth can effectively reduce NH3 volatilization in paddy soil under rice-based cropping system

Reduction of soil ammonia (NH3) volatilization is very important for improving nitrogen use efficiency and decreasing environmental risks in agricultural production. Two long-term paddy-upland rotations, garlic-rice (GR) and wheat-rice (WR), were conducted to investigate the influence factors and difference of NH3 volatilization in paddy. Results showed that compared with WR, the loss amount of NH3 volatilization under GR only decreased by 5.5
