Annean Station Management Plan, A A. Mitchell May 1983

Annean Station Management Plan, A A. Mitchell

Resource management technical reports

Annean Station's carrying capacity has been estimated at 8,340 sheep on its 168,539 hectares. The halophyte pastures of Carnegie Land System were in good condition while those of Mileura Land System were in poor condition. The wandarrie pasture of the Belele Land System was in fair to poor condition. This system comnprises 34 per cent of Annean's area and is estimated as capable of presently carrying 2,900 stock.

Hydrological Studies In Soil Salinity, C J. Henschke Jan 1983

Hydrological Studies In Soil Salinity, C J. Henschke

Resource management technical reports

Investigations involved examination of near-surface indurated layers to investigate their role in saltland formation. It was found that groundwater could move readily through this layer due to the presence of macro-pores. Close examination of apparently impermeable pallid zone clays, shows that decayed tree roots and large diameter voids provide a continuous pathway for the veritical transport of saline water from deeper aquifers.


Agricultural Water Quality Criteria : Irrigation Aspects., P R. George Jan 1983

Agricultural Water Quality Criteria : Irrigation Aspects., P R. George

Resource management technical reports

Water quality criteria for irrigation are imprecise. The final result of quality evaluation depends on plant, soil and climatic variables all of which can be inter-dependent. A range of management strategies of varying complexity are available to mitigate the effects of poor quality water. The heavy winter rainfall in the south-west of Western Australia affects the applicability of published salinity criteria most of which have been developed in arid and semi-arid environments with little effective rainfall.
