Leaf Scorch Of Apple Trees, N H. Shorter

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

BEFORE the 1964-65 fruit season, sections of a number of orchards in the Donnybrook district were converted to systems of permanent overhead sprinkler irrigation.

In several cases, however, leaf scorch occurred where these overhead sprinklers were used during the day time.

Soil Erosion And Farm Water Supplies, J C. Grasby, J. E. Watson

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

Water supplies for stock have an important influence on farm management.

In this article Soil Conservation Advisers J. C. Grasby and J. E. Watson discuss problems of soil erosion and farm water supplies.

Crossings For Channels And Drains In The Ord River Area, K S. Cole

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

ON farms irrigated by surface methods it is essential to provide crossings over channels and drains.

These crossings must be wide and strong enough to take the biggest farm machinery.

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.

Orchard Drainage, R G. Cahill

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

UNDERGROUND drainage of orchard land is an essential feature of fruitgrowing which is overlooked by many orchardists.

Soils should be adequately drained to cope with all winter rains.

Flooding Of Salt Land, C V. Malcolm

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

Many farmers have expressed concern and some have gone to considerable expense in trying to alleviate flooding problems on salt affected land.

Some consideration will be given here to flooding, its causes, effects on salt encroachment, methods of prevention and alleviation.

Healthy Pastures, F E. Ryan

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

IN sweeping away forests to make room for pastures we have taken on the responsibility of maintaining these areas in a condition suitable for the growth of pasture plants.

This is done by a choice of suitable species, fertilising, cultivating, drainage, control of grazing and by weed and insect control.

Kimberley Research Station : A Progress Report, Department Of Agriculture, Western Australia

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

INTEREST in the agricultural potential of the Kimberley region in Western Australia dates from its early exploration and settlement in the last century.

Several farming development schemes were considered for the area, but were never implemented.

This could be mainly attributable to lack of knowledge of agricultural potentialities, limitations of the local environment and ways of exploiting the local environment.

Up to the present the economy of the region is almost entirely based upon the extensive production of beef and to a lesser extent, wool.

Irrigation In Western Australia : Report On Government-Controlled Areas : 1958-59, H K. Gibsone

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

IRRIGATION in the south-western portion of Western Australia is mainly confined to the coastal plain west of the Darling Range where the three main irrigation districts of Harvey, Collie and Waroona have been established by the State Government.

The Government-controlled irrigation areas extend southward from Waroona (70 miles from Perth) to Dardanup (120 miles from Perth) and have an average width of about five miles.

Leaflet No 1003 - The Salt Problem In The Wheat Belt, G. H. Burvill

Bulletins 1 - 2999

IN the wheat belt of Western Australian bare patches in farm paddocks are often seen. Many are bare, or almost bare, because of too much salt in the soil. The excess of salt prevents the germination of seeds, or kills living plants, because it causes the water supply for germination or growth to be cut off. This salt problem is so serious in places that single farms or groups of farms have been ruined; wheat growing on them has become unprofitable.

Bulletin 115 - The Value Of Windmills For Pumping Water In Western Australia, A. H. Scott

Bulletins 1 - 2999

It is surprising to note the dearth of up-to-date reliable information dealing with actual results of modern windmills, under working conditions, though literature on thousands of other subjects less important can usually be obtained.

In this bulletin there is presented a complete and accurate record of the amount of water pumped daily by a windmill, under actual working conditions, for a period of 14 months.
