Spatial and temporal characteristics of soil water dynamics and crop yield response from a 4-year of lucerne and winter wheat rotation system in the Loess Plateau
黄土高原苜蓿-冬小麦轮作系统土壤水分时空动态及产量响应

Legume-cereal rotation is a major component of sustainable dryland farming systems in the Loess Plateau, China. Understanding the water dynamics of rotation after lucerne is therefore critical for crop sequence selection. Field experiments were undertaken from 2001 to 2003 in the Loess Plateau, western Gansu Province, China, to examine the water dynamics in rotation with winter wheat (WW) after a 4 years lucerne ley. The treatments were: lucerne ley (LC), lucerne removed for continuous fallow (LF), and the ...
