Department firm on salt

Collis, B. (1978) Department firm on salt. Farmer and Grazier, 11 May 1978. p. 6 [Publication] [Special Collections]


Special report on the Western Australian Agriculture Department's announcement of a farmer education plan based on the latest research findings into the state's salt problem.
The department's soil research officer, Clive Malcolm said the aim was to get farmers to understand causes of soil salinity with the department holding special saltland courses for farmers.
It has held two special courses so far, as well as an intensive in-service training on wheatbelt salinity for its own officers.
Clive Malcolm said that there was confusion about the amount of salt and the manner in which it was stored in the ground and the other was the way water moved through the ground and shifted the salt so it became a problem.
Research has shown water could leak upwards through cracks and root channels collecting salt from the clay as it went.
On reaching the surface it evaporated leaving salt crystals.
Although interceptor banks controlled surface seepage they could not control upwards seepage from the decomposed rock layer.
