The Development And Application Of Functions Describing Pasture Yield Responses To Phosphorus, Potassium And Sulfur In Australia Using Meta-Data Analysis And Derived Soil-Test Calibration Relationships, Cameron J P Gourley, David Weaver, Richard J. Simpson, Sharon R. Aarons, Murray M. Hannah, Ken I. Peverill

Natural Resources Research Articles

An improved ability to predict pasture dry matter (DM) yield response to applied phosphorus (P), potassium (K) and sulfur (S) is a crucial step in determining the production and economic benefits of fertiliser inputs and the environmental benefits associated with efficient nutrient use. The adoption and application of soil testing can make substantial improvements to nutrient use efficiency, but soil test interpretation needs to be based on the best available and most relevant experimental data. This paper reports on the development of improved national and regionally specific soil test–pasture yield response functions and critical soil test P, K and S …


Crop And Climate Suitability For Irrigated Agriculture In The Midlands Area Of Western Australia, 2nd Edition, Leon Van Wyk Jul 2019

Crop And Climate Suitability For Irrigated Agriculture In The Midlands Area Of Western Australia, 2nd Edition, Leon Van Wyk

Resource management technical reports

The Midlands groundwater and land assessment is a $4.7 million Water for Food project. Its aim is to confirm groundwater availability at one or more focus areas that may form precincts of 2000–3000 hectares suitable for intensive irrigated horticulture. This report forms part of this project.

Firstly, this report describes the climate of the Midlands study area and highlights the subtle differences between the two selected focus areas, Irwin and Dinner Hill. It discusses the importance of climate in determining crop suitability. We also investigated the following additional factors that determine crop suitability: water quality, water quantity, land capability (soils) …

Investigations Of The Potential For Irrigated Agriculture On The Bonaparte Plains: Land Capability Assessment Report, Henry Smolinski

Resource management technical reports

This report describes 55 000 hectares of predominantly red sands and sandy loams — locally referred to as Cockatoo Sands — on the Bonaparte Plains about 70 kilometres north of the Ord River Irrigation Area, Kununurra. It builds on soil surveys conducted in 2009 and 2015, which identified significant areas of red soils in the Kununurra area that could be suitable for agriculture.

The Cockatoo Sands generally have loamy, sand topsoils that grade to sandy loam with depth. The soil profiles are very deep, well drained to rapidly drained, and highly permeable. These soil characteristics support a large range of …
