Assessment Of Soil Sampling Equipment For Guiding Fertiliser Decisions, David Weaver, Robert Summers, David Rogers, Peta Richards, David Rowe

Resource management technical reports

A range of methods, technologies and equipment are used to collect representative composite soil samples from paddocks. Once collected, soil samples are analysed for various parameters that provide evidence to guide fertiliser decisions. The sampling methods, technologies and equipment used must result in samples that consistently represent the parameter of interest.

Soil sampling technology and equipment has advanced from manual devices (such as pogo-stick-style foot-thrust core samplers [pogo]) to a variety of mechanised core-thrust samplers and augers that are fitted to vehicles or battery drills. Each device may function differently under different conditions, and each requires differing levels of human …

Rehydrating The Landscape At Yanget, Geraldton, Western Australia, Jamie Bowyer, Rod O'Bree

Natural resources published reports

Rod and Bridie O’Bree’s farm is 25 km east of Geraldton in the Northern Agricultural Region of Western Australia. The long-term rainfall average is 486 mm although that has dropped to 354 mm over the last 30 years. They run a 150 head beef cattle herd, fatten 500-700 lambs annually and have a 40-60 head horse stud on the farm. They purchased the farm early in 2008 after one of the worst droughts in the area. There was little to no vegetation, brown or green, across the farm and all of the water from a 25 mm rain event ran …

The Applicability, Efficacy And Risks Of Natural Sequence Farming In The Dryland Agricultural Zone Of South West Western Australia, Nik Callow, Rose Anne Bell

Natural resources commissioned reports

Natural sequence farming (NSF) is an approach to restoring degraded agricultural land, developed by Peter Andrews on his property Tarwyn Park in New South Wales. The approach aims to rehydrate the landscape by slowing the movement of water with a series of structures and then using this water to drive plant growth and improve soil function.

The Department of Primary Industries and Regional Development engaged the University of Western Australia to review the applicability, efficacy and risks associated with using NSF principles and practices in the south-west dryland agricultural zone in Western Australia. The review has combined information from the …

Donnelly River Model Review, Justin Hughes

Natural resources commissioned reports

The Donnelly River Model was prepared for the Department of Water and Environment Regulation (DWER) by an external consultant (Hydrology and Risk Consultants) in 2018. The purpose of this model was largely to evaluate the feasibility of a proposed irrigation development centred on diversions from the Middle Donnelly near Chappel's Bridge into a reservoir in the nearby Record Brook catchment. As a part of the model build and reporting process, the HARC (2018) report was reviewed by Ecological Australia (2018) against the model specifications. ECL concluded that the model was "fit for purpose", but made many recommendations. Since re­port release, …
