Abstract
from yields, soil fertility, and greenhouse gas emission showed that the optimal ratio for discontinuous fertilization was 420 kg N haâ1 yrâ1 combined with straw incorporation of 10000 kg haâ1 yrâ1, whereas that for continuous fertilization was 300 kg N haâ1 yrâ1 combined with straw incorporation of 10000 kg haâ1 yrâ1. Thus, the DNDC model could effectively predict crop yields and SOC dynamics under discontinuous fertilization conditions in Hengshui. High and stable crop yields and enhanced soil fertility could be achieved by optimizing the ratio of fertilization rate to amount of incorporated straw.
