Replacing Farm Machinery, R Crossman
Replacing Farm Machinery, R Crossman
Journal of the Department of Agriculture, Western Australia, Series 4
In talking of machinery replacement it seems implied that the replacement items of plant are bigger and therefore better than their predecessers. It is also implied that plant replacement is becoming more costly.
Before any decision to replace machinery, the reason for replacement should be carefully considered.
There may be alternatives to the bigger and better solution.

Options For Machinery And Labour, A F. Herbert
Journal of the Department of Agriculture, Western Australia, Series 4
Machinery is one of the highest costs in farming today. It is not unusual for capital investment in machinery to be 20 to 30 percent of the total investment in the farm.
On an annual basis, expenditure directly attributable to machinery can be 40 per cent or more.
This article cannon be a panacea for everyone to reduce machinery costs - each farm is different. But some of the issues might be of help.

Contour Cultivation : Cheap Erosion Control, T R. Negus, B. Barrett
Journal of the Department of Agriculture, Western Australia, Series 4
Although the benefits of contour cultivation are well recognised, it makes cultivation more difficult, particularly if the paddock is split by contour banks and grassed waterways. However, a comparison east of Pingelly indicates that contour cultivation is little more expensive or time-consuming than ordinary cultivation.
Soil And Plant Analysis : A Guide To Fertilizer Usage, Walter Jacob Cox
Soil And Plant Analysis : A Guide To Fertilizer Usage, Walter Jacob Cox
Journal of the Department of Agriculture, Western Australia, Series 4
Soil and plant analysis can be used to identify problems in soils, diagnose nutrient deficiencies and as a guide to fertiliser usage.
Soil testing is particularily useful where large amounts of phosphorus and potassium are leached or removed from the paddock in hay or silage.
Actual rates of fertiliser can only be recommended from soil testing and only in conjunction with additional biological and economic information.

Progress In Clover Scorch Research, A Bokor, D. L. Chatel, D. A. Nicholas
Journal of the Department of Agriculture, Western Australia, Series 4
Considerable progress has been made with the clover scorch problem since the devastation of the 971 epidemic when intensive research began.
Over 2000 varieties and crossbreds of subterranean clover from various collections have been screened for resistance resulting in the release of the first resistant clover, Esperance, this year.
Benefits of fungicidal spraying have been demonstrated and low cost spraying programmes for grazed pastures, and seed and hay crops are under field investigation.
How Efficient Are Seeding Operations : Kondinin Work Study, E J. Roberts, C. R. Lester, J. E. Young
How Efficient Are Seeding Operations : Kondinin Work Study, E J. Roberts, C. R. Lester, J. E. Young
Journal of the Department of Agriculture, Western Australia, Series 4
The efficiency of machinery and labour during seeding operations was studied in 1977 by the Kondinin and Districts Farm Improvement Group and the Department of Agriculture. The aim was to find what influenced efficiency during cropping.
Time spent on activities during the working day was measured, and it was found that repairs, maintenance, meals and other incidental jobs considerably reduced the time spent driving the tractor.
Each farmer participating in the study was given the results of his own farm compared to the group, indicating tasks most needing improvement.

A New Approach To Grain Insect Control, G D. Rimes, M. T. Sexton
A New Approach To Grain Insect Control, G D. Rimes, M. T. Sexton
Journal of the Department of Agriculture, Western Australia, Series 4
Western Australian farmers now have a legal responsibility to control stored grain insects on their farms.
Ten species of insects, usually referred to collectively as 'weevils', have been 'declared' under the Agriculture and Related Resources Act.
In Western Australia, grain storage insects are not found in standing cereal crops. Thus, it should be possible to set up a clean delivery "pipeline" from the paddock to the C.B.H. bin.
