West Midlands Development : Cereals For The West Midlands, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
THE sandplain soils and climate of the West Midlands area are primarily suited to grazing.
However, the place of cereals is receiving a great deal of attention in view of their advantages in the early stages of development, and the need for the diversification of farm production.

TRIALS at the Badgingarra Research Station have indicated that many pasture species will grow in the West Midlands area.
Choice of the species most suited to any particular locality will be influenced by soil type, rainfall, grazing characteristics and possible ill-effects on stock.
The following species have been recommended.

FARMING the light lands of the West Midland area would be impossible without fertilisers.
Most light land areas are inherently very low in phosphate and also require nitrogen.
The nitrogen can come from fertiliser for cereal crops, or can be built up by growing appropriate legume pasture plants such as clovers and lupins.

Bulletin No 3547 - Kimberley Research Station - Progress Report 1968, Western Australian Department Of Agriculture
Bulletins - 3000 - 3999
Rivers flowing to the Gulf of Carpentaria and the Timor Sea have been estimated by hydrologists to carry about three times the water transported annually over the Murray drainage system and the South Eastern slopes which, together, comprise the highly settled agricultural areas of South Eastern Australia.
In 1945, the North Australian Development Committee recommended research in the Ord-Victoria rivers region as a first step toward ultimate agricultural development of this Northern potential and, in 1946, the Kim- berley Research Station commenced operations under the joint control of the Commonwealth Scientific and Industrial Research Organization and the Western Australian Department …

The Ord River Catchment Regeneration Project. 1. The Nature, Extent And Causes Of Erosion In The Ord River Catchment Area, K Fitzgerald
Journal of the Department of Agriculture, Western Australia, Series 4
OF the 17,800 square miles of Ord River catchment area, an estimated 1,450 square miles of country is subject to varying degrees of erosion.
This lies astride the Ord River and its major tributaries, the Elvire, Negri, Stirling, Panton, Turner, Nicholson and RB rivers.
The bulk of the eroded country lies in W.A. but part projects into the Northern Territory.

Cultivation : Does Haste Mean Waste?, H M. Fisher
Cultivation : Does Haste Mean Waste?, H M. Fisher
Journal of the Department of Agriculture, Western Australia, Series 4
Many farmers believe that increasing the speed of cultivation and seeding implements will cause deterioration of soils and reduced crop yields.
In a three-year trial on clover ley land at Wongan Hills higher cultivation speeds tended to increase rather than decrease wheat yields. There was some deterioration in the physical structure of the soil.
Leaf Scorching, Department Of Agriculture, Western Australia
Leaf Scorching, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
DURING the summer months, leaves of many plants develop browning and scorching which progresses inwards from the leaf margin or downwards from the leaf tip.
The affected parts become dry and brittle and may break away from the remaining green areas.

Journal of the Department of Agriculture, Western Australia, Series 4
"Puccinellia" is a tussocky perennial grass with an outstanding ability to survive salty and waterlogged conditions.
Considerable areas of saltland in Western Australia are suited to its growth.
Seed is now available commercially and in this article the conditions to which the grass is suited are described and establishment and management methods are suggested.
Seed And Pasture Rates For New Dairy Pastures, F E. Ryan
Seed And Pasture Rates For New Dairy Pastures, F E. Ryan
Journal of the Department of Agriculture, Western Australia, Series 4
THE success or failure of pasture establishment on new land often depends on the interaction of rate of seeding and rate of superphosphate application.
Every year large areas of virgin land are cleared and sown to pasture in the higher rainfall areas, and all-too often the new pasture is not as successful as it should be because too little super is applied, and, in some cases, too little seed.

Journal of the Department of Agriculture, Western Australia, Series 4
THE illustration shows a large area of severely salt affected land near Narembeen.
Before treatment, sheep had access to the area and in summer broke the topsoil into a fine powder which lifted to form dust storms with every good breeze.

Planning New Farm Dams : Excavated Earth Tanks, J E. Watson, J. C. Grasby
Journal of the Department of Agriculture, Western Australia, Series 4
A GOOD farm dam is a valuable asset, and well worth its cost, but there are many aspects to consider when a new dam is required. Careful planning with adequate testing and checking will help to get the best value for money and reduce the chance of costly failures.
This article discusses these aspects in relation to the excavated earth tank type of dam.

Flooding And Salt Problems In The Wheatbelt, Department Of Agriculture, Western Australia
Flooding And Salt Problems In The Wheatbelt, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
VALUABLE land has become salty in parts of the West Australian agricultural areas because most of the surrounding land has been cleared and developed for agriculture.
This salting of a small proportion of the land is part of the price paid for the development of agriculture in this State.
Drainage is not the answer to the wheatbelt flooding and salt land problems.
A more practical approach is to limit runoff from sloping land, and to make good use of salt-affected land by growing salt tolerant perennial pastures on it, says the Soils Division of the Department of Agriculture.

The Gascoyne River Catchment Area, W M. Nunn
Journal of the Department of Agriculture, Western Australia, Series 4
A RECENT Department of Agriculture survey of the Gascoyne River catchment area has indicated that deterioration of plant cover in the area contributes to the severity of floods which regularly damage the town of Carnarvon.
It is hoped that the results of the survey will help efforts to regenerate the catchment area, and reduce the risk of flooding.

Molybdenum Deficiency On Lighter Soils, Edgar Noel Fitzpatrick
Journal of the Department of Agriculture, Western Australia, Series 4
WIDESPREAD occurrences of molybdenum deficiency of subterranean clover have been observed on sandy and gfravelly surfaced soils in recent years, and present indications are that molybdenum will join copper and zinc as a major trace element deficiency of many of these soils.
