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.

Sealing Farm Dams, I A F Laing, R. G. Pepper

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

Research over the past 10 years has shown that it is technically possible to seal many leaking farm dams. In some situations a cheap chemical treatment is effective but in most cases it is cheaper to construct a replacement dam.

This article reviews the situation in western Australia and outlines some of the methods used for sealing dams.

1976 Sunflower-Safflower Irrigated Variety Trial 1976-1977, G J. Parlevliet

Experimental Summaries - Plant Research

In 1975/76 two varieties of sunflower, Hysun 10 and Hysun 20, as well as Safflower (Gila) were grown in a large alternative crop demonstration. Results were sufficiently good to warrant more and closer examination. This led to the present variety trial using varieties suggested by Mr. M. Poole. The aim was to evaluate six sunflower varieties and one safflower. The work was carried out in the light of reduced profitability of peas, beans and some fruit crops. This results in a number of growers having irrigation water and equipment under-employed. Other farmers are after a crop which will give them …
