Diagnosing And Ameliorating Problem Soils : Decision Tree On How To Diagnose And Ameliorate Problem Soils, Department Of Agriculture And Food, Western Australia Aug 2005

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 Jun 2005

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 May 2005

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 Jan 2005

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.

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 …


Sustainable Tourism Along Maine's Coast, Natalie Springuel Jan 2005

Sustainable Tourism Along Maine's Coast, Natalie Springuel

Maine Sea Grant Publications

Tourism is Maine's largest industry. In 2003, tourism generated $ 13.4 billion in sales of goods and services. In 2004, tourism provided for 176,633 jobs, generated $3.8 billion in wages, and $530 million in tax revenues. Governor John Baldacci formally recognized the economic and ecological importance of tourism by highlighting it as one of the five primary industries at the Governor's 2003 Conference on Natural Resource-based Industries. Access to the natural resource base, and the need to collaborate with other resource-dependent industries, were identified at the conference as cutting across multiple industries, including tourism. Since the Governor's Conference, several studies …

Mole Drainage For Increased Productivity In The South West Irrigation Area, D L. Bennett, Richard George, Bill Russell Jan 2005

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 …
