Diagnosing And Ameliorating Problem Soils : Decision Tree On How To Diagnose And Ameliorate Problem Soils, Department Of Agriculture And Food, Western Australia
Diagnosing And Ameliorating Problem Soils : Decision Tree On How To Diagnose And Ameliorate Problem Soils, Department Of Agriculture And Food, Western Australia
Agriculture reports
Most cropping paddocks in Western Australia have lower yielding areas within paddocks that perform poorly in most years. If the agronomy and management are good, the poor yields are usually due to soil-related problems. Some of these problems can be corrected or reduced by adopting certain proven practices. However, it is important to identify and quantify the problem so that decisions can be made on whether amelioration is possible and economically feasible. The objective is to provide a simploe decision tool for farmers and advisers to use in identifying and quantifying soil problems in agricultural soils in Western Australia. It …
Roaded Catchments To Improve Reliability Of Farm Dams, David Stanton
Roaded Catchments To Improve Reliability Of Farm Dams, David Stanton
Bulletins 4000 -
Maintaining reliable on-farm water supplies is an on-going challenge for landholders throughout Western Australia. Improving reliability of dams by constructing a roaded catchment is one of the most cost-effective methods of improving the performance and reliability of a farm water supply.
A roaded catchment is a water-harvesting structure designed to increase the amount of run-off from the catchment above a dam. The 'roads' of a roaded catchment are parallel ridges of earth with batters (or side slopes) that cause run-off to be directed into troughs or channels. The surface is lined with clay and compacted to make it smooth and …
Pastoral Stock Water Workbook, T M. Sincliar, F A. Bright
Pastoral Stock Water Workbook, T M. Sincliar, F A. Bright
Agriculture reports
The Pastoral Stock Water Workbook has been developed to assist you to estimate the costs of maintaining stock water and make informed decisions about managing existing and proposed water points. The first half of the Workbook provides background information on stock water points, their usage, advantages and disadvantages. Whilst the second part contains a series of stepby- step exercises that should be completed as you progress through the Workbook. The latter part of the Workbook aims to: • Show a worked example of the annual costs of maintaining water; • Provide tools to calculate water costs for your business; • …

Deep Drainage Is It For Me? Workshop Manual For Participants, Richard Odonnell
Deep Drainage Is It For Me? Workshop Manual For Participants, Richard Odonnell
Agriculture reports
A Million Hectares for the Future. This workshop forms part of a series of workshops dealing with dryland salinity and options to manage it. All of the workshops have the common theme of identifying the risk at the catchment and farm level, assessing the potential consequences if the risk is not managed and determining the course of action to be taken. You will be able to determine the course of action based on your specific circumstances and goals. There is no one recipe that is suited to all situations.

Introduction To Salinity - Workshop Manual For Participants, T M. Lacey
Agriculture reports
This is the first in a series of workshops looking at dryland salinity and options to manage it. These ?Million hectares? workshops have the common themes of environmental improvement. They provide information to help participants identify the risks within the catchment and at a farm level, assess both the likelihood of the risk occurring and consequences if the risk is not managed and determine the best course of action for individual. Participants will determine their courses of action based on their specific circumstances and goals. There is no one recipe that is suited to all participants. The Participants Notes when …
Mole Drainage For Increased Productivity In The South West Irrigation Area, D L. Bennett, Richard George, Bill Russell
Mole Drainage For Increased Productivity In The South West Irrigation Area, D L. Bennett, Richard George, Bill Russell
Bulletins 4000 -
Heavy soils, with low rates of soil-water movement, such as those found in the South-West Irrigation Area (SWIA), require closely spaced (2-6 m apart) subsoil drainage systems to provide sufficient water movement to control the effects of salt-waterlogging on pastures. Such close spacing using traditional buried pipe or tile drainage systems is impractical. As a result, mole drainage systems, used in other parts of the world for over 50 years, have gained popularity in the SWIA in recent years.
This Bulletin Farmnote reports the current ‘best-bet’ mole draining technique for SWIA conditions gathered from observations over a number of years …
