Researcher(s) Peter Kealy (SFS)
Bruce Wightman (DNRE/SFS)
Year(s) 1996, 1998
Contributor Southern Farming Systems
Trial location(s) Gnarwarre, VIC
Controlled traffic drainage project locations
Aims

To report on crop expansion and improved yields with reduced risk through the development of cheap and effective drainage techniques suitable for south west Victoria.

Key messages
  • Observations in N.S.W., Victoria and Western Australia clearly show that tap rooted crops have excellent straight tap roots when grown on beds when compared to flat paddocks. 
  • These initial considerations suggest narrow raised beds may offer a better overall soil water exploration throughout different depths of the profile and a better depth of rooting by crops.
