Improving water use efficiency – reducing soil evaporation locations
Aims

To use a thick layer of cereal straw maintained within the growing season to focus on reducing the amount of moisture lost to soil evaporation.

Key messages
  • The addition of a straw layer acted to reduce evaporation and significantly increased grain yields and water use efficiency in 2010 and 2011 at 3 field sites.
  • Soil evaporation also decreased with increasing light interception from larger crop canopies.
