Wiping Out Tall Weeds, Brad Rayner
Wiping Out Tall Weeds, Brad Rayner
Journal of the Department of Agriculture, Western Australia, Series 4
Control of weeds is an on-going battle for farmers, with many weapons becoming increasingly expensive. A refreshing exception to this trend is the blanket wiper, a cheap but effective meens of applying herbicides to taller weeds in pasture. Brad Rayner explains how it works.
Soil Sampling Made Easier, Mike Bolland, Mike Baker
Soil Sampling Made Easier, Mike Bolland, Mike Baker
Journal of the Department of Agriculture, Western Australia, Series 4
A new rotary blade soil sampler has taken the hard work out of collecting soil samples from Western Australia's hard-setting soils to test for soil phosphorus levels .
Conceived and developed by Department of Agriculture technical officer Mike Baker, it should enable soil testing to be more widely adopted. Fortunately, the soil calibration tests that were developed using pogo samples can also be used for the new sampler.

The Development Of An Efficient Lupin Harvesting Front, E D. Blanchard
The Development Of An Efficient Lupin Harvesting Front, E D. Blanchard
Journal of the Department of Agriculture, Western Australia, Series 4
Harvest losses represent a significant reduction in lupin production and farm productivity.
Since 1984, the Department's Farm Machinery Research and Liaison Unit at the Dryland Research Institute has studied the lupin harvesting operation to improve its mechanical efficiency. An experimental and a prototype harvesting front were built and tested in the field. Guidlines for efficient lupin harvesting were produced, and commercial modifications developed.

Improved Fertilizing Practices On The Peel-Harvey Catchment, P T. Arkell
Journal of the Department of Agriculture, Western Australia, Series 4
Broad-acre farmers in the Peel-Harvey catchment have met a challange and achieved a great deal since the fertilizer extension programme started in 1983.
The main objective of the extension programme has been to ensure that every year three-quarters of the farmers make economically and technically sound fertilizer decisions, thus causing a minimum amount of phosphorus to enter the waterways of the Peel-Harvey estuarine system.
Options For Machinery And Labour, A F. Herbert
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.
Matching Tractors And Implements, I W. Grevis-James
Matching Tractors And Implements, I W. Grevis-James
Journal of the Department of Agriculture, Western Australia, Series 4

Simplifying Lubricants For Farm Machinery, R A. Platt
Journal of the Department of Agriculture, Western Australia, Series 4
All moving parts on machinery needs lubrication. With the rapid development in farm machinery and its attendant sophistifications, the stresses imposed on the lubricants have also increased.
This article looks at some of the changes in requirements and developments in lubricants available.
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.
Service And Spare Parts, D Hosken
Service And Spare Parts, D Hosken
Journal of the Department of Agriculture, Western Australia, Series 4
Service is the preparation, delivery and after-sales maintenance of machinery. It involves responsibilities for both the dealer and the purchaser.
Getting The Best From Tractor Tyres, J Quealy
Getting The Best From Tractor Tyres, J Quealy
Journal of the Department of Agriculture, Western Australia, Series 4
The amount of pull a tractor develops depends largely on tyre efficiency and so with so many tyre size options for the one tractor model it is very easy to make the wrong decision on tyre fitment.
Tyre efficiency varies with tractor weight, soil conditions, inflation pressure and tyre size.
Hers we look at some of these factors and how changing them may affect efficiency.
There's Little To Choose Between Scarifier Points, C R. Lester
There's Little To Choose Between Scarifier Points, C R. Lester
Journal of the Department of Agriculture, Western Australia, Series 4
Tests on scarifier points showed that methods of treating them to prolong their life had little effect.
Calibration Of Boom Sprays, J R. Peirce
Calibration Of Boom Sprays, J R. Peirce
Journal of the Department of Agriculture, Western Australia, Series 4
Boom sprays have become increasingly common on Western Australian farms, allowing farmers to take advantage of modern herbicided.
Most boom sprays used on farms have 50 cm nozzle spacings and require calibrating regularily to ensure accurate herbicide application.
By following these steps, the boom will deliver accurate amounts of herbicide.

How Many Acres Per Hour?, J G. Drever
How Many Acres Per Hour?, J G. Drever
Journal of the Department of Agriculture, Western Australia, Series 4
MANY farm tractor operators don't know exactly how much land is covered in an hour by implements drawn by their tractors. This information, useful on any farm where tractors are used, is of particular value in contract work.
The capacity of the machine or implement, or in other words, its rate of working, depends on the width of the machine, how fast it travels, how efficiently it is operated and the time it works.
