A Review Of The Economics Of Regenerative Agriculture In Western Australia, Anne Bennett
A Review Of The Economics Of Regenerative Agriculture In Western Australia, Anne Bennett
All other publications
- There is no published work detailing the economics of regenerative agriculture in Western Australia.
- Of the work completed in other jurisdictions and nations captured in this review, the profitability of regenerative agriculture compared with conventional agriculture was variable, although generally lower.
- The loss of income associated with the transition from conventional agriculture to regenerative agriculture is a significant barrier to adoption, although it is enterprise-sensitive.
- Farmers who are operating regenerative agriculture systems self-report higher levels of wellbeing.
- Conventional agriculture and regenerative agriculture are overlapping approaches.
- The literature presented in this review is mostly based on small samples, case studies or …
Optlime, A Bioecenomic Model Of Soil Acidity Management In Agricultural Systems, Chris Gazey
Optlime, A Bioecenomic Model Of Soil Acidity Management In Agricultural Systems, Chris Gazey
All other publications
Optlime is a model that represents the essential biological, physical and economic factors related to soil acidity management in Western Australia. The model allows users to define site and soil characteristics for an acidic scenario and then simultaneously assess likely outcomes for 2 different lime sources and application strategies. With and without liming scenarios are examined over a 20 year simulation so as to capture the long-term impacts of soil acidity management. Output provided allows you to examine the likely effect of liming on pH, exchangeable aluminium, yields, and profits. An investment appraisal is provided to show you how liming …

Field Pea In The Great Southern, Ian Pritchard, Rodger Beermier, Mark Seymour
Field Pea In The Great Southern, Ian Pritchard, Rodger Beermier, Mark Seymour
All other publications
Semi-leafless field pea like Kaspa have lifted the benchmark set by the previous conventional varieties such as Parafield and Dunwa. Semi-leafless field pea have the same traits as conventional field pea: adaptation to a range of soil types; wide selection of weed control options (including crop topping); nitrogen input; disease break; and reduction in root lesion nematodes. Semi-leafless pea is easier to harvest and is less prone to pod shatter.

Sustainability Issues For Agriculture In Western Australia, Anne Bennett, Ross Kingwell, Ross George
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.
Published Salinity Information And Wa Farmers. An Investigation Into The Effectiveness Of Current Published Salinity Information, Stephen Lloyd
Published Salinity Information And Wa Farmers. An Investigation Into The Effectiveness Of Current Published Salinity Information, Stephen Lloyd
Agriculture reports
Salinity is one of the greatest environmental threats facing Western Australia. Extension of salinity information to WA farmers is a key process in helping the rural community manage this threat. Published information is an important part of this extension. However, there has been very little research into the use and effectiveness of published salinity information. The aim of this study was to investigate:
• Effectiveness of current salinity information products and services in relation to decision making and practice change by WA farmers;
• Possible improvement in salinity publications to better assist WA farmers in decision making and practice change.

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 …

Napier-King Land Conservation District : Land Management Manual, Peter Hocking
Napier-King Land Conservation District : Land Management Manual, Peter Hocking
All other publications
With the discovery of the role of trace elements, large tracts of land in the south west of Western Australia, previously regarded as unsuitable for agriculture, were cleared in the 1950s and 1960s. Much of this land was taken up as Conditional Purchase Blocks, a scheme which enabled conversion of unalienated crown land to freehold title providing a set proportion of the block was 'developed'.
However, the removal of the natural deep rooted vegetation and its replacement with pasture species (up to 90% of privately owned land in the Napier-King LCD area is cleared) has not been without problems. The …

An Evaluation Of The Remnant Vegetation Protection Scheme 1988-1991 : A Report, Department Of Agriculture And Food, Western Australia, Soil And Land Conservation Council (W.A.)
All other publications
The objective of the Remnant Vegetation Protection Scheme is to encourage land owners to fence and protect areas of remnant vegetation for the purposes of flora and fauna conservation, land conservation and aesthetics. The means by which land owners are encouraged to protect remnant vegetation is the provision of a grant equal to half the cost of labour and materials to erect a stock-proof fence around the vegetation concerned. The RVPS is jointly administered by the Departments of Conservation and Land Management (CALM) and Agriculture (DAWA), with the latter as the lead agency. CALM contributes substantially to the RVPS through …
