Harvested And Grazed Lupin Stubbles On Following Wheat South Carrabin., J W. Bowden
Harvested And Grazed Lupin Stubbles On Following Wheat South Carrabin., J W. Bowden
Experimental Summaries - Plant Research
Location: South Carrabin lease block
Harvested and grazed lupin stubbles on following wheat. Trial 86M8
This trial is difficult to analyze statistically because of the treatment changes induced by sheep breaking in to some of the plots. Further, lupin grain yields were not very high and so differences between harvested and unharvested treatments are not large. Also the grazing intensity was not very severe (except on the unintentionally grazed plots) and so the effect of grazing is also relatively small.
Trial 87M7
Nitrogen phosphorus and irrigation of wheat.
Location: South Carrabin.
This trial was designed to give a nitrogen/phosphorus response …

Phosphorus Levels And Disease On Lupins, J W. Bowden
Phosphorus Levels And Disease On Lupins, J W. Bowden
Experimental Summaries - Plant Research
Trial 87LG39 (81LG29) 87ME62
Location: Pingaring.
It has been suggested that high levels of phosphorus application to lupins can reduce the impact of leaf and root diseases. Two old rotation trials provided a range of disease burdens, across which phosphate rates on lupins were applied. Disease scores, vegetative yields, phosphorus concentration and seed yields were measured.

Residual Value Of Phosphate Fertilizers., M D A Bolland, M Baker, C. H. Phillips, D. Proudmore
Experimental Summaries - Plant Research
Trial 84M63
Residual value of phosphate fertilizers.
Location: South Carrabin Block of Merredin Research Station.
4th successive crop on new land. Trial has shown that the effectiveness of the different types of rock phosphate were about the fifth to one tenth as effective as the fresh (triple) superphosphate applied in 1984. The effectiveness of the superphosphate, decreased by 60 between year 1 and 2, and by a further 10-15% by 1987. This experiment will continue as pasture for 1988 and 1989, and will be re-cropped in 1990. The experiment is also assessing soil testing for P. but soil test data …
How Important Is Sulphur For Pastures?, R N. Glencross, W. J. Cox
How Important Is Sulphur For Pastures?, R N. Glencross, W. J. Cox
Journal of the Department of Agriculture, Western Australia, Series 4
With the introduction of low sulphur compound and concentrated fertilisers, a new look is required at the sulphur status of West Australian soils, and the sulphur requirement of pasture.
In this article the functions of sulphur, deficiency symptoms and potential problem soils are described.
Current recommendations and plans for future research work are outlined.

The Phosphorus Fertilisers : How They Compare, Walter Jacob Cox
Journal of the Department of Agriculture, Western Australia, Series 4
ALTHOUGH 'double' or 'concentrated' superphosphate was first commercially manufactured in 1872 it was not until the 1950's that it became a major commercial fertiliser. In 1965 it accounted for about 15 per cent, of the world production of phosphatic fertilisers.
The Effects Of Shearing Time And Stocking Rate On Wool Production, R J. Lightfoot
The Effects Of Shearing Time And Stocking Rate On Wool Production, R J. Lightfoot
Journal of the Department of Agriculture, Western Australia, Series 4
THE results of the first experiment comparing "autumn" versus "spring" shearing over a two-year period were published in 1960.
In this experiment the autumn-shorn ewes cut heavier greasy fleeces (even though they also reared considerably more lambs) with less tender wool, resulting in a higher average return per head from this group.
The autumn-shorn wool carried more seed, was less attractive and contained relatively more pieces than did the spring-shorn wool.

Put Garden Rubbish To Work In A Compost Heap, W Dawson
Journal of the Department of Agriculture, Western Australia, Series 4
THERE'S a surprising amount of mumbo jumbo written about the simple compost heap. By the time you've waded through all the instructions, you feel as if you ought to have prerequisites of a doctorate in soil chemistry or an unbroken ancestry of at least three generations of professional English gardeners.

Control Of Copper, Zinc And Manganese Deficiencies In Fruit Trees, N J. Halse
Journal of the Department of Agriculture, Western Australia, Series 4
THE three elements copper, zinc and manganese are plant nutrients of the type often referred to as minor or trace elements.
Although essential elements for plant growth, they are required in comparatively small quantities.

Minor Elements Can Be Overdone, L T. Jones
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 …
