Agenda: Water Organizations In A Changing West, University Of Colorado Boulder. Natural Resources Law Center Jun 1994

Agenda: Water Organizations In A Changing West, University Of Colorado Boulder. Natural Resources Law Center

Water Organizations in a Changing West (Summer Conference, June 14-16)

Conference organizers, faculty and/or moderators included University of Colorado School of Law professors Lawrence J. MacDonnell, David H. Getches and James N. Corbridge, Jr.

Water organizations in the western United States range from small, traditional acequia associations to large metropolitan water suppliers. What do these vastly different kinds of organizations have in common? All are feeling the pressures of change in the region--growing urban populations, environmental concerns, and calls for public participation.

This year's summer program will examine how water organizations are adapting to these pressures for change. Speakers drawn from urban, agricultural, and community organizations will share their experiences …


Drought Profile: Haryana State In North India, K. Kailasa Nathan Jun 1994

Drought Profile: Haryana State In North India, K. Kailasa Nathan

Drought Network News (1994–2001)

Haryana state is considered the breadbasket of India, along with the Punjab state. The effects of drought (and mitigation of those effects) are, therefore, of considerable importance for the state. This article considers the state’s drought profile through a study of six drought years in Haryana.


Bulletin 4283 - Nitrogen Fertilisers For Cereal Production, M. G. Mason Mar 1994

Bulletin 4283 - Nitrogen Fertilisers For Cereal Production, M. G. Mason

Bulletins 4000 -

Because fertiliser prices are high, it is important to understand what affects the response to fertilisers by crops.

Among the many factors influencing crop response to nitrogen applications, the most important are the season, soil type, paddock history, time of application and source of nitrogen. Before deciding whether to use nitrogen on a cereal crop, which source to use and at what rate, you need some understanding of how these factors work.

Greatest responses to nitrogen fertilisers can be expected in areas with a relatively long growing season. In such areas light soils with a low nitrogen status give the …


Bulletin 4278 - How To Use Wide Furrow Sowing For Improved Crop Production On Water Repellent Sand, Paul Blackwell, Grant Morrow, Tony Webster Feb 1994

Bulletin 4278 - How To Use Wide Furrow Sowing For Improved Crop Production On Water Repellent Sand, Paul Blackwell, Grant Morrow, Tony Webster

Bulletins 4000 -

Wide furrow sowing is a method for successfully establishing crops of lupins or cereals on non-wetting sands, and improving crop establishment on non-repellent sands. The same principles can be used to assist establishment of fodder shrubs and long-term pasture (e.g. tagasaste and Rhodes grass).


Land Resources Of The Northam Region, Neil Clifton Lantzke, I Fulton Jan 1994

Land Resources Of The Northam Region, Neil Clifton Lantzke, I Fulton

Land resources series

This report presents soil and landform mapping of about one million hectares in the Avon Valley and central wheatbelt of Western Australia at scale of 1:100,000. The study area spans from the lateritic plateau of the Darling Range to the broad, flat landscape of the wheatbelt and covers four broad physiographic regions: • the Zone of Ancient Drainage; • the Zone of Rejuvenated Drainage; • the West Kokeby Zone; and • the Darling Range Zone. Twenty-five soil landscape units were identified and mapped on the accompanying map sheets. A soil landscape unit is an area of land that occurs in …


An Inventory And Condition Survey Of The Murchison River Catchment, Western Australia, Peter James Curry, A L. Payne, K A. Leighton, P Hennig, D A. Blood Jan 1994

An Inventory And Condition Survey Of The Murchison River Catchment, Western Australia, Peter James Curry, A L. Payne, K A. Leighton, P Hennig, D A. Blood

Technical Bulletins

The inventory and condition survey of the Murchison River catchment and surrounds, undertaken by the Department of Agriculture between 1985 and 1988, describes and maps the natural resources of the region’s pastoral leasehold land. This survey report provides a baseline record of the existence and condition of the natural area’s resources, to assist with the planning and implementation of land management practices. The report identified and described the condition of soils, landforms, vegetation, habitat, ecosystems, and declared plants and animals. It also assessed the impact of pastoralism and made land management recommendations. The area surveyed by field work during 1985-88 …

Resource Inventory And Condition Survey Of The Ord River Regeneration Reserve, John De Salis Dec 1993

Resource Inventory And Condition Survey Of The Ord River Regeneration Reserve, John De Salis

Natural resources published reports

It is now some 33 years since the Ord River Regeneration Project, the largest and most ambitious of its kind in Australian rangelands, commenced.

During this time there have been a number of publications and miscellaneous reports about the project, but this publication is by far the most comprehensive produced to date. Although the field work was undertaken in 1981, the findings recorded here will stand in a good stead as a detailed account and reference work for years to come.

Much has changed within the Regeneration Reserve area since the project commenced. Cattle and feral donkey numbers have finally …

Miscellaneous Publication 42/93 - Development And Dissemination Of Design Methods For Rangeland Paddocks Which Maximise Animal Production And Minimise Land Degradation, Shane Cridland, Mark Stafford Smith Dec 1993

Miscellaneous Publication 42/93 - Development And Dissemination Of Design Methods For Rangeland Paddocks Which Maximise Animal Production And Minimise Land Degradation, Shane Cridland, Mark Stafford Smith

Animal production and livestock published reports

Surveys of rangeland resources in Western Australia to date have shown that 23% of the area surveyed is in poor range condition. Poor condition is characterised by the loss of perennial vegetation allowing wind and water erosion. Approximately another 37% is in only fair range condition (Curry and Hacker 1990).

The loss of range condition is partly due to uneven use of paddocks by sheep and cattle. The areas close to water and the preferred pasture types are often over-utilised, while areas well away from water and less preferred pasture types are under-utilised. The result is that rangeland in good, …


Strategic Minerals In The New World Order, Kent H. Butts Nov 1993

Strategic Minerals In The New World Order, Kent H. Butts

Books, Monographs & Collaborative Studies

The author discusses U.S. dependence on overseas sources of strategic minerals essential to sustain its economy and defense sector. U.S. vulnerability to a loss of access to important mineral supplies is more pronounced now than at any time since World War II. The uneven distribution of strategic mineral reserves and their concentration in a handful of politically unstable countries make it essential that U.S. policymakers ensure mineral availability in the new world order. The author considers the geographical imbalance of mineral trade patterns, evaluates the stability of the major strategic mineral producing countries, and assesses the potential for mineral supply …
