Fossils And Farmers. 2. The Ice Age, D Merrilees

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

What did the giant Australian marsupials of the "Ice Age" look like?

Fossil remains found by farmers could help reconstruct them, as well as giving some idea of conditions on the Australian continent at that time, says D. Merrilees, B.Sc, acting Curator of Palaeontology at the West Australian Museum.

Good Pasture On A Problem Soil, R Sprivulis

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

The acid peaty sands of the South-West have always been problem soils, and are often considered useless.

But, by following recommended establishment methods, farmers like Mr. F. E. Bellanger, of Nornalup, have shown that it can carry valuable pasture.

Minor Elements Can Be Overdone, L T. Jones

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

T H E term "minor elements" which is now commonly used and well understood by farmers and gardeners, refers to the five essential plant foods—copper, zinc, manganese, molybdenum and boron.

These five essential plant foods are needed by all plants in minute quantities and it is relatively easy to use them in excess of actual requirements or even in toxic amounts.

In practice this is not usually a problem with cereals and pastures. The important exception is when zinc alone is added to a cereal crop low in copper and the extra zinc accentuates the copper deficiency, and poorer yields …

Establishing Saltland Pastures, C V. Malcolm

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

WITH the approach of winter, thoughts are turning to the seeding season. It will therefore be appropriate to discuss methods of establishing saltland pastures.

This discussion will be restricted to "bluebush," creeping saltbush, and old man saltbush. Seed of these plants is available from local stock firms.

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.

Potassium Deficiency In Medium Rainfall Areas, William John Toms

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

IT is well known that potassic fertilisers must be used for the successful growth of subterranean clover (Trifolium subterraneum L.) on many soils in the higher rainfall districts of Western Australia.

Recent investigations have shown that some soils in medium rainfall districts are also too low in potassium to grow healthy subterranean clover pastures.

Correcting Cobalt Deficiency, Laurence C. Snook

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

COBALT is essential in the food eaten by sheep and cattle. As little as one part of cobalt in 10,000,000 parts of food appears to be adequate.

But if this mere trace is missing, ruminants will waste away and die, even when the feed appears excellent In every other way.

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.

The Use Of Lime In Market Gardens, Department Of Agriculture, Western Australia

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

THE term "lime" when used in relation to agriculture means any calcium containing material that is capable of correcting soil acidity.

While generally used for this purpose, lime has many other equally important functions in the soil.

Salty Seepages Can Be Productive, C V. Malcolm

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

MUCH has been said and written concerning the use of Paspalum vaginatum for growing on seepage areas, but the general production to be expected from seepage areas has not received much attention.

The fact is that properly handled, seepage areas can be quite productive, and can be valuable for summer grazing.
