LIRAC - Long-term changes of a sodic soil 14-years after lime and gypsum application locations

To investigate the effects of different soil ameliorants at different rates on sodic soils.

Key messages
  • Changes in soil chemistry were found 14 years after application of high rates of lime and gypsum.
  • The source of Ca (lime, gypsum or lime + gypsum) had no significant impact on the long term displacement of Na hy Ca.
  • The practical message is that any source of Ca, applied at an equivalent Ca rate, gives equal long term benefits in Na displacement.
  • Soil chemistry did not change below 30 cm depth.
  • Plant yields have been low due to drought. In 2002 there was no significant difference in plant growth after different ameliorants. This result may not be true and may have occurred because of the low yields.
