Farm Dams In The Wheatbelt, I A F Laing

Journal of the Department of Agriculture, Western Australia, Series 4

Of the estimated 76 000 farm dams in the wheatbelt, about 8 per cent either leak or are salt affected. The remaining 70 000 dams are capable of holding water for livestock use and can be regarded as sercicable dams.

A great many of the serviceable dams are unreliable water supplies due to the combined effects of lack of runoff from catchments, shallow depth of storage and small size of storage in relation to expected demand from livestock and evaporation loss.

Economics Of Farm Water Supplies, P P. Eckersley

Journal of the Department of Agriculture, Western Australia, Series 4

The economics of farm water supplies can be studied in two ways. One is to compare the costs of alternative ways of supplying a specified quantity of water to a farm. Another is to calcu;ate how mucha farmer can afford or will pay for a water supply.

I propose to look at these questions from the point of vieew of an eastern wheatbelt farmer, assuming that he must pay the full costs of any water supply provided for his property.

Cost Of Farm Water Supplies : Conclusions From Surveys, I A F Laing

Journal of the Department of Agriculture, Western Australia, Series 4

The Department of Agriculture, in conjunction with the Farm Water Supply Advisory Committee, has conducted farm wster supply surveys in many districts in the wheatbelt.

The aim of the surveys was to collect data to assess the existing water supplies, the potential for further water supply developments and to compare the relative difficulty of water supply development in different localities.

Thirty seven of these trials consisted of four replications on wheat only and the other seven consisted of three replications on wheat, oats and barley. All reps were soil sampled separately. In each rep. of the 37 trials, 20 samples were taken to 10 cm depth with pogo stick samplers. In the. other seven trials 50 samples per rep. were taken.

P.W.D. Supplementary Public Water Supply Schemes, J E. Davis

Journal of the Department of Agriculture, Western Australia, Series 4

Shallow wells and soaks with very limited yields were the principal water sources for the early settlers.

Hundreds of such wells were constructed by the Public Works Department in remote areas.

In the early 1930s major development of water supplies from rock catchments was begun in the central wheatbelt.

After the war, larger and more effective earth moving equipment became available. The Public Works Department rehabilitated many old excavated dams as well as constructing new ones.

Roaded catchments were also developed during this post-war period. many farmers took advantage of Public Works Department technical advise and hired a P.W.D. grader …

Some Basics Of Marron Production, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

marron are native to the South-West of Western Australia, and are keenly sought by inland fisher-men. However, supplies do not equal the apparent demand.

One solution is to cultivate marron in farm dams, or more intensively as a commercial enterprise.

This article suggests a few guidelines for marron production.

Lupin Trials, J Moore

Experimental Summaries - Plant Research

Trials in lupins this year concentrated on testing herbicide for post emergence use in lupins. Of the 20 herbicides tested 12 did not cause significant decreases in crop density and/or yield. However, weed control was often poor and the herbicide phytotoxicity tended to vary between sites. (Chapman, Badgingarra and Avondale). The Chapman and Avondale trials were not harvested because of drought. Trials in 1978 should determine if any of the herbicides tested can safely be recommended. Lupins - summary.

Native Plants : Water Savers In The Garden, K S. Cole

Journal of the Department of Agriculture, Western Australia, Series 4

The climate of Western Australia may be one of the best in the world for people but it is a difficult one for many of our imported, and common garden plants. as a consequence, some 70 per cent of our summer water usage is for gardens and lawns.

This is not the sort of statistic that we should accept easily or happily.

There is a solution to this problem: a new approach to home gardening is required.

The new garden is based on W. A.'s own colourful native plants, which are adapted to mild winters, hot dey summers and poor …

Groundwater In The Wheatbelt, E P. O'Driscoll

Journal of the Department of Agriculture, Western Australia, Series 4

In general six factors affect the occurence of groundwater; rainfall, topography, rock type, rock structurs, vegetation, and local evaporation.

Variation in even one of these can affect the potential yield of a bore or well, the groundwater salinity, and even whether any groundwater occurs at all.
