Report Card On Sustainable Natural Resource Use In Agriculture, Robert Summers, David Weaver Sep 2013

Report Card On Sustainable Natural Resource Use In Agriculture, Robert Summers, David Weaver

All other publications

Condition and trend Nutrients, such as phosphorus (P), are essential for profitable agriculture in the south-west of WA; however, excess P – more than is required for optimal production – is stored in many agricultural soils. On average, pasture soils and arable soils contain 1.3 times and 1.6 times respectively, as much P as is required for optimal production. Production in P-enriched soils is more likely to be constrained by soil acidity (50–60% of pasture and arable soils), potassium (K) (50% of pasture soils and less than 10% of arable soils), and sulphur (S) (30% of pasture soils). Management implications …

Soil Peels: Their Preparation And Presentation, Tim D. Overheu

All other publications

Soil peels are an exciting and inexpensive technique for collecting an exact reproduction of soil profiles. They are an excellent product for displays and soil extension activities. Introduced in the mid-1960s, the soil peel (lackfilm) technique was initially developed using a flexible glue product in combination with a cloth base, and was used to preserve soil stratigraphy at geo-archaeological excavations (Voight & Gittins 1977). The method described in this update introduces refinements to the technique for heavy and consolidated clay or duplex soils in Western Australia. Applying and removingtechnique was initially developed using a flexible glue product in combination with …

Western Australian Resource Condition Monitoring Projects 2007-2009, Ceidwen Pengelly, 2010 Jan 2010

Western Australian Resource Condition Monitoring Projects 2007-2009, Ceidwen Pengelly, 2010

All other publications

Monitoring the status and trends of our natural resources is the only way we can assess whether the actions that have been implemented are making a difference. The impetus for this resource condition monitoring program (RCM) was the recognition that our monitoring networks, baseline data and data management systems were inadequate to enable quantitative reporting to government, and the community, on the difference their investments in natural resource management were making. It was considered that making a significant investment in raising our ability to report would be a long-lasting legacy of value to the state.
