Horticultural Capability Study Of Soils Adjacent To Plantations At Carnarvon, Western Australia, M R. Wells, J A. Bessell-Browne

Resource management technical reports

A detailed soil survey and horticultural capability assessment was undertaken over 1,804 ha of land adjacent to existing plantations on levees of the Gascoyne River near Carnarvon. The study provides mapped land resource data and advice in relation to land management and the possibility of further land release for horticulture. In the assessment of horticultural capability primary consideration has been given to the risk of erosion during flood events, to salinity, and to soil drainage conditions.

Toward Better Minimum Tillage For South-Coastal Sandplain Soils, W L. Crabtree

Resource management technical reports

Seventeen farmers compared their conventional cropping practices with some form of minimum tillage cropping. The minimum tilled crops yielded 21 percent less grain than the conventionally sown crops. The reasons for these decreased yields were in most cases related to inexperienced management. The minimum tilled treatments usually had very poor weed kill strategies which often resulted in large weeds at sowing, very cloddy seed-beds, and numerous insects in the young crops.

An Economic Model For Evaluating Strategies On The South Coast Of W.A. Which Reduce Wind Erosion : Documentation, A D. Bathgate

Resource management technical reports

The sandplain region on the south coast has predominately sandy soils which are subject to erosive winds when ground cover is likely to be scarce. This can often result in production losses of crop and pasture. There is concern that wind erosion will lead to the depletion of the soil resource in the long term. The model is multi-period linear programming with a planning horizon of 10 years. Effects of wind erosion on production can be imposed on the model for the first five years after the erosion event.

Phosphorus Retention Of Sandy Horticultural Soils On The Swan Coastal Plain, Ian Mcpharlin, Neil Delroy, Bob Jeffery, Greg Dellar, Maurice Eales

Journal of the Department of Agriculture, Western Australia, Series 4

Soils can be ranked according to their phosphorus retention capacity by the phosphorus retention index (PRI). This is the ratio of phosphorus adsorbed by soil to that remaining in solution under a set of standard conditions. Although it is a laboratory measurement, the PRI seems to be a good indication of what happens in practice.

Shallow Drains For Reducing Waterlogging And Salinity On Clay Flats, Don Mcfarlane, Tim Negus, Arjen Ryder

Journal of the Department of Agriculture, Western Australia, Series 4

Flooding, waterlogging and salinity are problems which commonly occur together on the broad valleys of the wheatbelt. Drainage lines often become poorly defined once they reach the valleys and flood waters spread out, causing inundation and waterlogging. This excess water needs to be controlled because it contributes to salinity

Salinity And Waterlogging On The Esperance Downs Research Station, D J. Mcfarlane, A T. Ryder

Resource management technical reports

Details the situation on the station so that the demonstration and research programs can be designed and the effect of the treatments assessed. Past work on the station has been briefly summarised and the results of geophysical surveys and additional drilling are given. Surveys of electromagnetic terrain conductivities have shown where salinity is most serious at present. The most deeply penetrating method may have identified areas likely to developing salinity in future.

Geraldton Rural-Residential Land Capability Study, R A. Dye, A M E Van Vreeswyk, Geoff Allan Moore

Land resources series

With a growing population in the Geraldton area, there is a demand for rural and coastal subdivision to provide for rural residential development and intensification of agricultural activities. Future land use planning for land use change and management of land to overcome existing land degradation problems should be based on land capability. This study provides a semi-detailed (1:50,000) soil and landform inventory for the immediate zone around Geraldton, south from Coronation Beach to Cape Burney along the coast, 13.7 km inland in the north and 7.6 km inland in the south. Eight land systems were identified in the land resource …
