Economics Of Interceptor Drains : A Case Study, Andrew Bathgate, Ian Evans
Economics Of Interceptor Drains : A Case Study, Andrew Bathgate, Ian Evans
Journal of the Department of Agriculture, Western Australia, Series 4
This case study determines the most likely rate of return to capital invested in constructing seepage interceptor drains to reduce the effect of waterlogging on crop and pasture yields. The analysis of a farm in the Denbarker region, west of Albany, determined what increases were needed in pasture growth to justify the cost of constructing drains across four adjacent paddocks. The benefits of changing rotations to include lupins were also determined, as growing lupins was unprofitable before the construction of drains.

Trials in 1968 at Burracoppin and York again showed it is safer to topdress urea just before seeding than to drill a mixture of seed and urea.
At all but the lowest urea rates, urea drilled with the seed reduced the number of plants emerging and surviving, and reduced final wheat yields.

A New Type Of Seed Bed Cover For The Market Garden, R R. Bell, M. Hardie
Journal of the Department of Agriculture, Western Australia, Series 4
ALL market gardeners use seed beds in their gardening programme. However, the basic design of seed beds and covers has not greatly altered over the years.
The availability of cheap good quality plastic materials has now shown the way to improvements in the design of this type of gardening equipment.

Making Your Own Beehives, R S. Coleman
Journal of the Department of Agriculture, Western Australia, Series 4
THE publication of this article runs counter to my own principles to some extent as I have long maintained that most beekeepers will find it cheaper in the long run to purchase factory-made hives and frames.
I realise, however, that many apiarists possess both the skill and equipment to make hive-bodies, and that some at least can occupy slack periods profitably in this manner.
