Land Systems Of The Kimberley Region, Western Australia, A L. Payne, N Schoknecht

Technical Bulletins

The Land Systems of the Kimberley Region Report describes and maps the landscapes, soils and vegetation of the Kimberley region. This report is a consolidation of surveys carried out by different organisations, across different areas of the Kimberley, since the 1940s. The Kimberley region, as defined in this bulletin, covers 330 070km². The report categorises the Kimberley region into 111 land systems. Under each land system, the report identifies the vulnerabilities of those areas, and provides recommendations on how to achieve sustainable use. The report also publishes pasture types for the entire region and the grazing potential for each pasture, …

Soil Test And Phosphorus Rate For High Rainfall Clover Pastures, Robert Summers, David Weaver

Bulletins 4000 -

Essential information for soil testing to determine the phosphorus fertiliser requirements for clover pastures in high rainfall coastal areas of Western Australia. Includes procedures for soil sampling, tissue testing, liming, when to apply fertiliser, how to decide on the target production level, how much fertiliser is required and type of fertiliser.

Native Vegetation In Western Australia Is Actively Involved With Soil Formation, Doug Sawkins, William H. Verboom, John S. Pate

Bulletins 4000 -

Many adverse situations in Western Australian agriculture have arisen because in the past we cleared native perennial vegetation below safe ecological limits in order to grow annual crops and pasture. In retrospect, we did not fully understand the functioning of the native ecosystems concerned and thus did not foresee the long-term consequences. Research into the survival techniques of native species provides important lessons for future farming. By understanding the behaviour of plants and soils we can maximise their use in a sustainable way. Knowledge of the water acquisition and storage strategies of native plants in seasonally dry areas may be …

Greener Pastures 5 - Managing Sulphur In Dairy Pastures, Mike Bolland, Ian Guthridge, Bill Russell, Martin Staines, John Lucey, Richard Morris

Bulletins 4000 -

During 1999-2009, soil testing for sulfur (S) was undertaken on 48 paddocks at the Vasse Research Centre (VRC) at Busselton, in the south-west of Western Australia (WA).

Paddocks had been grazed intensively by dairy cows and their young stock over a period of 10 years, as part of the Vasse Milk Farmlets and Greener Pastures farming system projects. Pasture consisted of annual ryegrasses with some subterranean clover. Soils in the 48 paddocks were 1-2 m sand to sandy loam over massive clay, known locally as Abba sand. For many soils in the region, including Abba sands, the topography is flat …

Greener Pastures 1 - The Greener Pasture Project: Managing Nutrients In Dairy Pastures, John Lucey, Mike Bolland, Don Bennett, Richard Morris, Bill Russell, Martin Staines

Bulletins 4000 -

As dairy farmers have strived to maintain profitability, many have farmed more intensively. More cows are milked and increasing inputs of fertiliser and purchased feed are used per hectare. However, these increased nutrient inputs have far exceeded the increase in nutrient output in milk production. The increasing nutrient surplus (inputs minus outputs) from intensification on dairy farms has met with increasing community concern about the environmental footprint of the dairy industry. In some other countries, dairy farmers who have intensified by increasing nitrogen inputs are now faced with legislation controlling the amount of fertiliser nitrogen that they can use.

Greener Pastures 6 - Managing Soil Acidity In Dairy Pastures, Mike Bolland, Bill Russell, Martin Staines, Richard Morris, John Lucey, D L. Bennett

Bulletins 4000 -

During 1999-2009, soil testing for pH (in CaCl2) was used to determine lime application for 48 paddocks at the Vasse Research Centre at Busselton, in the south-west of Western Australia (WA).

Paddocks had been grazed intensively by dairy cows and their young stock over a period of 10 years, as part of the Vasse Milk Farmlets and Greener Pastures farming system projects. Pasture consisted of annual ryegrasses with some subterranean clover. Soils in the 48 paddocks were 1-2 m sand to sandy loam over massive clay, known locally as Abba sand.

Greener Pastures 2 - Nitrogen For Intensively Grazed Dairy Pastures, Martin Staines, Richard Morris, Tess Casson, Mike Bolland, Bill Russell, Ian Guthridge, John Lucey, Don Bennett

Bulletins 4000 -

We undertook three main studies during the Greener Pastures project:

1. From mid 2005 to late 2008, a farming systems study was undertaken with five rates of nitrogen fertiliser as the main treatment. This study will be referred to as the ‘nitrogen response farmlets’.

2. From 2006 to 2008 a series of smaller ‘supporting’ studies were completed to investigate how grazing management influences the pasture production gains from nitrogen fertiliser. This will be referred to as the ‘nitrogen by growth-stage study’.

3. From early 2009 to early 2010, a farming systems study was undertaken to investigate the potential to increase …

Greener Pastures 4 - Managing Potassium In Dairy Pastures, Mike Bolland, Ian Guthridge, Bill Russell, Martin Staines, John Lucey, Richard Morris

Bulletins 4000 -

We undertook three studies into the potassium requirements of high rainfall pastures: 1. Between 1999 and 2009, soil testing was conducted in 48 dairy paddocks at Vasse Research Centre (VRC) in the south-west of Western Australia (WA). This study will be referred to as the VRC soil test study.

2. Between 2002 and 2007, a potassium experiment was undertaken at Boyanup to improve our knowledge of potassium requirements of intensively grazed ryegrass pastures. This will be referred to as the Boyanup potassium experiment.

3. Between 2006 and 2010, potassium experiments were undertaken on two partner farms of the Greener Pastures …

Adaptive Management For A Turbulent Future, Craig R. Allen, Joseph J. Fontaine, Kevin L. Pope, Ahjond S. Garmestani

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

The conceptual underpinnings for adaptive management are simple; there will always be inherent uncertainty and unpredictability in the dynamics and behavior of complex ecological systems as a result non-linear interactions among components and emergence, yet management decisions must still be made. The strength of adaptive management is in the recognition and confrontation of such uncertainty. Rather than ignore uncertainty, or use it to preclude management actions, adaptive management can foster resilience and flexibility to cope with an uncertain future, and develop safe to fail management approaches that acknowledge inevitable changes and surprises. Since its initial introduction, adaptive management has been …

"We Are The Owners": Autonomy And Natural Resources In Northeastern Nicaragua, Mary Finley-Brook

Geography and the Environment Faculty Publications

Although focused predominately on Miskitu politics, this chapter identifies various constraints to multi-ethnic self-determination, while noting barriers exist even among aid programs targeting political empowerment and community development. Nevertheless, I also explore examples of progress toward decentralization at regional and local levels regardless of an overall national context of political containment and economic exploitation.

Landscapes And Soils Of The Lake Grace District, D N. Sawkins
