Extended Data Fig. 2: The relative contribution (%) of explaining variables to yields under best management practices.
From: Soil quality both increases crop production and improves resilience to climate change
Assessment was conducted by GBRT models based on the primary data comprising all on-farm trials in major cropping systems in China. Orange, green and blue bars indicate climate, soil and management variables respectively. Tmax and Tmin, maximum and minimum temperature; PRE, precipitation; GDD, growing degree days; RAD, solar radiation; SOM, soil organic matter; Olsen-P and Avail-K, soil available phosphorus and potassium. W-NCP, winter wheat in North China Plain; W-YZB, winter wheat in Yangtze River Basin; W-NWC, winter wheat in Northwest China; M-NEC, rainfed maize in Northeast China; M-NCP, maize in North China Plain; M-SWC, rainfed maize in Southwest China; SR-YZB, single rice in Yangtze River Basin; ER-SC, early rice in South China; LR-SC, late rice in South China.
