Seepage Interceptor Drains For Reducing Waterlogging And Salinity, Don Mcfarlane, Jim Cox Jan 1990

Seepage Interceptor Drains For Reducing Waterlogging And Salinity, Don Mcfarlane, Jim Cox

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

Shallow interceptor drains can reduce waterlogging on sloping sites. Such drains will more than pay for themselves from the increased crop yield. Recent work has shown that these drains also decrease salinity so that they are cost-effective in the long as well as the short term.


Level Banks Used To Decrease Waterlogging Can Increase Salinity, Don Mcfarlane, Richard Engel, Arjen Ryder, Maurice Eales Jan 1990

Level Banks Used To Decrease Waterlogging Can Increase Salinity, Don Mcfarlane, Richard Engel, Arjen Ryder, Maurice Eales

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

Some farmers have used level W1SALTS banks to control surface zvaters above areas affected by ivaterlogging and salinity. Because the amount of waterlogging has been reduced, crop yields have increased downslope of some banks. However, the banks divert fresh surface water into deeper salty groundwater and, in the long term, worsen salinity. This article details an investigation of the effect of level WIS ALTS banks on saline groundwaters and discusses alternative methods of preventing the waterlogging of saline areas.


What Are Land Conservation Districts?, Western Australian Department Of Agriculture Jan 1990

What Are Land Conservation Districts?, Western Australian Department Of Agriculture

Natural resources published reports

Land conservation groups need your support. Land degradation is not just a farming problem. We change the land and waters in many ways, whether it be clearing of precious natural bush or through the fertilizers which leach from our gardens.

By learning about the Land Conservation Districts achievements and understanding the challenges they face we can better see our own place in the scheme of things.

We will learn the ways to organize for Landcare in other rural areas, or in the city, that will be successful.

This is what the Decade of Landcare is all about - providing an …


Plantscan, Ted Lefroy, Fritz Droge Jan 1990

Plantscan, Ted Lefroy, Fritz Droge

Natural resources published reports

PLANTSCAN is a network of schools and landholders throughout the wheatbelt of Western Australia. It aims to speed up the process of testing plants for their suitability to this environment.

This kit contains seed of various trees and shrubs and notes on how to grow them, plant them out into a small plot and record their progress.

Schools and landholders throughout the wheatbelt who have purchased this kit become part of a research network aimed at selecting plants that will:

* overcome soil erosion;

* overcome soil salinity;

* and provide a source of income for farmers.

The following sheets …


Salinity And Waterlogging On The Esperance Downs Research Station, D J. Mcfarlane, A T. Ryder Jan 1990

Salinity And Waterlogging On The Esperance Downs Research Station, D J. Mcfarlane, A T. Ryder

Resource management technical reports

Details the situation on the station so that the demonstration and research programs can be designed and the effect of the treatments assessed. Past work on the station has been briefly summarised and the results of geophysical surveys and additional drilling are given. Surveys of electromagnetic terrain conductivities have shown where salinity is most serious at present. The most deeply penetrating method may have identified areas likely to developing salinity in future.
