Spectacular Recovery In The Ord River Catchment, A L. Payne, I W. Watson, P E. Novelly
Agriculture reports
Regeneration work on severely damaged country in what is now known as the Ord River Regeneration Reserve (ORRR) commenced in 1960. The ORRR is in the East Kimberley area of Western Australia with an associated small area in the Northern Territory. The work included strip contour cultivation and seeding (which proceeded at various levels of intensity during the 1960s, 1970s and 1980s), fencing and destocking of cattle by mustering over many years, and the eradication of donkeys.

Sustainability Issues For Agriculture In Western Australia, Anne Bennett, Ross Kingwell, Ross George
Agriculture reports
This paper describes briefly the main challenges to the sustainability of agriculture in Western Australia and outlines some means of responding the the challenges: market-based approaches; agricultural and environmental research and development; accelerated adjustment; and global and national policy initiatives. Challenges include: land resource quality (salinity, soil acidity), biodiversity, greenhouse gas emissions, climate change, water availability, food safety, and pests and diseases.

Agriculture reports
Soil quality is critically important for the long-term production of high quality and high yielding fruit and vegetable crops in the Carnarvon horticultural district of Western Australia. A stable soil structure is essential for good soil quality.
Phosphorus And Nitrate Loss From Horticulture On The Swan Coastal Plain, Neil Clifton Lantzke
Phosphorus And Nitrate Loss From Horticulture On The Swan Coastal Plain, Neil Clifton Lantzke
Agriculture reports
(En) The extent of nutrient loss from nine horticultural properties located on the sandy soils of the Swan Coastal Plain was examined. On three of the properties phosphorus (P) loss was measured by monitoring nutrient loads in shallow drains. On the other six properties networks of monitoring bores were installed and both P and nitrate nitrogen (NO3-N) concentrations were monitored. All of the properties except one were located on the low phosphate fixing Bassendean sands. The level of nutrient loss was depend l production areas. High to very high N03-N concentrations were found in the shallow groundwater beneath the production …
