Winchester Sub-Catchment Management Plan, Vivian T. Read
Winchester Sub-Catchment Management Plan, Vivian T. Read
Soil conservation survey collection
The 590 Ha Winchester sub-catchment has no apparent external drainage. Groundwater levels are rising causing site specific problems. Wind erosion has severely affected some areas.The objective of this report is to provide a sub-catchment management plan that is based on sustainable agricultural systems and a hydrological equilibrium. The recommendations aim to meet this objective in the long term. Recommendations to achieve short term results are considered separately. These measures have relatively high installation and maintenance costs. They should be considered as interim management methods until the recommendations for long-term control become effective (perhaps 3 - 5 years after implementation).

Trial 89KA11
Location: Great Southern Agricultural Institute - Farm Paddock B15
Main objectives of this trial was to evaluate the lines for their resistance to blue-green aphid, redlegged earthmite and lucerne flea. However since the site lacked a substantial infestation of blue-green aphid and lucerne flea, our efforts were concentrated on redlegged earthmite resistance.

It will require the total cooperation of all members of the Soil Conservation District to remedy the area's problems. The first priority is for the control and better use of water on the recharge areas. The wheat/wheat/lupin rotation at present offers the best economic option. Lupins are well suited to the areas of lighter land. If lupins are planted on waterlogged soils or otherwise unsuitable soils, problems will arise and perhaps prejudice their use on the widespread suitable areas. The use of trees below rocky outcrops is an important measure to prevent excessive recharge of the deeper aquifers. Where trees …

The "Soil Show" Final Report, B E. Bessen
The "Soil Show" Final Report, B E. Bessen
Soil conservation survey collection
This project began with a requirement to produce a poster display for the Soil Conservation Districts Regional Workshops, in July 1988. A multi-dimensional display was produced at each of three workshops, accompanied by extensive publicity cover. As a result of the success of the displays, it was decided to maximise the exposure possible and tackle the Agricultural Show circuit. The Soil Show then travelled 7900 km, taking in 12 venues involving 16 days of public exposure in 10 weeks. It attracted up to 340 people per hour and won a number of awards. However, the major achievements were the significant …

The Role Of Building Surveyors In Rural Land Use Planning, Roni Oma
The Role Of Building Surveyors In Rural Land Use Planning, Roni Oma
Soil conservation survey collection
The State Planning Commission has prepared a draft "Rural Land Use Planning Policy" which aims to provide an effective framework for planning in rural areas. The Policy proposes that local authorities currently experiencing land use conflicts or pressure for development and subdivision, prepare a Local Rural Strategy prior to the Commission considering any major development proposals.

The Agriculture And Land Description Of The Midlands, Wongan Hills And Dalwallinu Districts Of W.A., D N. Sawkins
Agriculture reports
This report deals with the area of responsibility of the Moora District Office of the W.A. Department of Agriculture. The Moora advisory district consists of seven shires which cover 2,811,400 hectares. Agriculture in the advisory district varies according to climate and soil type, Sheep and cattle production are the main enterprises in the high rainfall (coastal) areas. Mixed cereal sheep production is the main system in the medium and low rainfall areas with cereals increasing in importance as annual rainfall diminishes.
Eastern Wheatbelt Farm Economics, Peter Eckersley
Eastern Wheatbelt Farm Economics, Peter Eckersley
Soil conservation survey collection
This booklet outlines the current cost structure and profitability of a farm in the eastern wheatbelt. Rather than being figures for an 'average farm', they reflect the use of practices widely recommended by the Department of Agriculture on a typical property in the area. This does not mean the Department of Agriculture believes every farm in the area should be run this way. The best way to run any particular farm depends on the resources and objectives of that farmer.

Report On A Visit To Israel August-September 1964, D J. Carder
Report On A Visit To Israel August-September 1964, D J. Carder
Soil conservation survey collection
The main features in which farming methods and the environment in Israel differ from those in Western Australia, as they appeared to me, are:- the dominant sedimentary and limestone geology with its accompanying soil and moisture conditions population pressure which puts a premium on agricultural productivity and research the widespread use of sprinkler irrigation. These factors interact in various ways so that, although many problems are similar in the two countries (both have many pioneering problems remaining) the approaches to them vary considerably.
