Saving The Catchments Of Albany's Harbours, Ashley Prout
Saving The Catchments Of Albany's Harbours, Ashley Prout
Journal of the Department of Agriculture, Western Australia, Series 4
Fertiliser, particularly phosphorus, running off farm land is a major source of nutrient entering Albany's harbours. Oyster Harbour, which has a large rural catchment, is especially at risk.
The build-up in nutrients in the harbours has caused nuisance algal growth since the early 1970s and subseuent death of more than half the seagrass beds, which are vital to the areas marine life.
The Department of Agriculture, at the request of the Environmental protection Authority, has developed and promoted catchment management plans that enable rural land holders to reduce the amount of run-off into the harbours without necessarily sacrificing farm productivity. …
Water Erosion Of Farmland In 1988, K J. Bligh
Water Erosion Of Farmland In 1988, K J. Bligh
Journal of the Department of Agriculture, Western Australia, Series 4
Widespread heavy rains in WesternAustralian agricultural areas in 1988 caused severe water erosion, much of which could have been avoided by minimum cultivation and lower stocking rates.
Coastal Plains : Land Use And The Environment, P R. George
Coastal Plains : Land Use And The Environment, P R. George
Journal of the Department of Agriculture, Western Australia, Series 4
Five years ago, this Journal of Agriculture reported on ways to overcome severe algal pollution of the Peel-Harvey estuarine system, 70 km south of Perth.
Several articles in this Journal of Agriculture discuss improved agricultural practices on the Swan Coastal Plain in particular, although the principals will apply to similar eutrophication of the Slbany harbours, Wilson Inlet and the Vassee-Wonnerup Estuary. They also emphasixe the fine balance between man's demand for potable water and land for rural, industrial and urban use.
Dust Elimination From Outdoor Feedlots For Sheep, D J. Carter
Dust Elimination From Outdoor Feedlots For Sheep, D J. Carter
Journal of the Department of Agriculture, Western Australia, Series 4
The humble woodchip, widwly used as a soil mulch in Western Australian gardens, is set tto take a new role as a dust inhibito in assembly yards used to hold live sheep for export.
Research by the Department of Agriculture's Soil Conservation Service Branch has shown that, of the materials tested, woodchips were the most effective in preventing dust being generated. Wind speeds had to approach a "near gale" before dust developedfrom the protected soil.
The use of woodchips, therefore, provides a practical alternative to stabalising the soil and preventing an environmental problem associated with one of the State's valuable …
Seepage Interceptor Drains And Topsoil Salinity, T R. Negus
Seepage Interceptor Drains And Topsoil Salinity, T R. Negus
Journal of the Department of Agriculture, Western Australia, Series 4
The Department of Agriculture established 121 trials in its Narrogin advisory district starting in 1972 to measure the effect of bulldozer and grader built seepage interceptor banks and drains on the topsoil salinity of the land downslope of them.
After 14 years of moniterin, there was no evidence that seepage interceptor drains and banks reduced the top soil salinity on 10 of the 11 sites in the Pingelly, Brookton and Wickepin Shires.
Feral Donkeys : An Assessment Of Control In The Kimberley, S H. Wheeler
Feral Donkeys : An Assessment Of Control In The Kimberley, S H. Wheeler
Journal of the Department of Agriculture, Western Australia, Series 4
Feral donkeys are one of the major limitations to increased pastoral production in many parts of the Kimberley area of Western Australia, where they compete with cattle for food. In addition donkeys are aggressive animals, driving cattle from watering points and better grazing areas. They eliminate perenial plants by overgrazing and therefore reduce the carrying capacity of the range.
Originally introduced as draught animals, donkeys were released when cars arrived; since then they have bred up to large numbers in many areas.
For several years the Agricultural Protection Board has undertaken a programme of donkey shooting from helicopters. Since this …
How Saltland Can Be Reclaimed, A J. Peck
How Saltland Can Be Reclaimed, A J. Peck
Journal of the Department of Agriculture, Western Australia, Series 4
Some possibilities for reclamation of saltland.
Some Concepts In Rangeland Management, R B. Hacker
Some Concepts In Rangeland Management, R B. Hacker
Journal of the Department of Agriculture, Western Australia, Series 4
The arid and semi-arid zones of Australia occupy about 75 per cent of the land mass. The pastoral industries are located within these zones and, although productivity per unit area is low, the region nevertheless constitutes one of the nation's valuable renewable resources.
If properly managed, such a resource may be maintained as a productive asset indefinitely.
Grey Kangaroo Management Programme, Department Of Agriculture, Western Australia
Grey Kangaroo Management Programme, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
The Grey Kangaroo Management Programme, introduced in 1971 by the Department of Fisheries and Fauna, is designed to ensure the long-term conservation of the grey kangaroo, while at the same time recognising the right of the landholder to protect his primary production from damage.
One of the points which has arisen after examination of the programme is that some individual farmers are not fully aware of the requirements of the regulations.
Tree Establishment In The Wheatbelt, F Batini
Tree Establishment In The Wheatbelt, F Batini
Journal of the Department of Agriculture, Western Australia, Series 4
Although most of the Forests Department's activity has centred around the State Forests in the higher rainfall areas, the Department has, for many years, encouraged the planting and conservation of trees throughout the farming areas.
Overgrazing And Wind Erosion, J R H Riches
Overgrazing And Wind Erosion, J R H Riches
Journal of the Department of Agriculture, Western Australia, Series 4
OVER the last few years wind erosion during the autumn in the wheatbelt districts has become increasingly evident.
This has occurred under normal seasonal conditions and observations in this article are not related to unusual conditions such as the extremely low rainfall during the current season.*
Pasture : Corner-Stone Of Soil Conservation, W J. Burdass
Pasture : Corner-Stone Of Soil Conservation, W J. Burdass
Journal of the Department of Agriculture, Western Australia, Series 4
LEGUME PASTURE is the basis of prosperity in farming in the agricultural areas of Western Australia.
The livestock industry could not thrive without it and it also maintains fertility and soil structure for the cereal growing industry.
It is, in fact, the comer-stone on which the soil conservation conscious farmer rests his soil management.
Multiple Cropping Will Increase The Erosion Hazard, W J. Burdass
Multiple Cropping Will Increase The Erosion Hazard, W J. Burdass
Journal of the Department of Agriculture, Western Australia, Series 4
WITH the low price of wool and the price of wheat high in comparison, farmers need little encouragement to increase their acreage of crops.
Unfortunately with increased cropping comes the risk of increased erosion—unless there is a simultaneous increase in the use of conservation practices.
Winter Management Of Salt Land, T C. Stoneman
Winter Management Of Salt Land, T C. Stoneman
Journal of the Department of Agriculture, Western Australia, Series 4
WITH the emergence of crops, many farmers will again be seeing bare patches or thin stands of cereals due to salt accumulation.
Would these areas be better left out of cultivation, or should they have been planted to saltbush and bluebush?
Reclaiming Salt Land With Bluebush, Stanley Thomas Smith
Reclaiming Salt Land With Bluebush, Stanley Thomas Smith
Journal of the Department of Agriculture, Western Australia, Series 4
IN Western Australia there are approximately a million acres of salt land, some of which is a serious economic problem to individual farmers, unfortunate enough to have the major portion of their properties affected by salt encroachment.
