Waterlogging : One Reason Why Our Crops And Pastures Are Not Achieving Maximum Yields, Department Of Agriculture And Food, Western Australia

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

Water, either its lack"or excess, is the main factor affecting the yield of crops and pastures in Western Australia.

The Extent And Cost Of Waterlogging, Don Mcfarlane, Buddy Wheaton

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

Waterlogging is an underrated and not widely recognized problem in our cropping areas. Before we can tackle the problem through drainage and alternative cropping systems, we need to know its extent and how much crop yield is lost. The effect of waterlogging on pasture growth is also poorly known.

Jerdacuttup Land Resource And Capability Study, Geoff Allan Moore, S T. Gee, D Vincent

Resource management technical reports

The Jerdacuttup catchment on the south coast of Western Australia has a number of significant land degradation problems. A soil-landform map of the catchment was produced at a scale of 1:50,000. The map units are a combination of landform and soil type. A land capability assessment was undertaken for five land uses; improved annual pastures, perennial pastures, lucerne, cereal cropping and lupins, using a five class classification.

Preliminary Groundwater And Salinity Investigation In The Eastern Wheatbelt. 1. Brennand's Catchment, Richard J. George Dr, P W C Frantom

Resource management technical reports

Groundwaters were found to be 10 m below the floor of the ancestral playa lake in Brennand's catchment. They were extremely saline. A groundwater flow system was not established on much of the catchment. Flow was observed to be occurring from recharge areas near the playa lakes towards the midslopes of the catchment. Flow was apparently restricted from leaving Brennand's catchment because of obstruction to groundwaters created by dolerite dykes.

Busselton - Margaret River - Augusta Land Capability Study : Methodology And Results, Peter J. Tille, Neil Clifton Lantzke

Resource management technical reports

A land unit map of the region has been prepared at a scale of 1:50,000. Additional maps of climate, surface and groundwater supplies and existing land use have also been prepared at smaller scales. The capability of each of the land units to support grazing, market gardens, vineyards, orchards and forestry has been assessed. The limitations for housing on small rural lots have also been evaluated. Describes the methods by which the survey was undertakenand will be primary of use to the technical user.

Spacing Water Points In The Southern Pastoral Areas Of Western Australia, Don Burnside, Adrian Williams, Peter Curry

Bulletins 4000 -

An inadequate distribution of watering points in our pastoral lands, particularly in the saltbush/bluebush pasture, has caused localisized land degradation close to waters and reduced animal productivity (particularly in stressful times). From experimentation and observation, some generalised recommendations for water supply distribution in pastoral areas can be made.

Floristic Survey Of Remnant Vegetation In The Dandaragan Area, Western Australia, Edward Arnold Griffin

Resource management technical reports

A study involving the documentation of the extent and floristic composition of patches of native vegetation left uncleared by agricultural development is described. Floristic regions were defined in the study area by detailed analysis of the floristic data. The concentration of the major conservation reserves in only a few of these regions left the floristic variation of most of these regions poorly represented conservation reserves. About 13 percent of the private property remains uncleared.

Busselton, Margaret River, Augusta: Land Capability Study, Peter J. Tille, Neil Clifton Lantzke

Land resources series

The study was done to ensure that information on the area's land resource, and its capability, is available for land use planning. This information will assist planners to make decisions which can allow for the optimal development of the land while avoiding land degradation or land use conflicts. A map showing the distribution of land units defined according to soil type, topography, drainage and wind exposure was prepared at a scale of 1:50,000. From this map a smaller scale, less detailed land systems map was drawn. Land capability, the ability of land to sustain a specific use without undesirable on-site …

Soils Of The Ivanhoe Plain, East Kimberley, Western Australia, J M. Aldrick, M H R Van Cuylenburg, P W. Moody, B A. Wren, A J. Clarke

Technical Bulletins

The Ivanhoe Plain was divided into two geomorphic provinces. The principal difference between the provinces is the time during which pedogenesis occurred. The crcking clay soils of the northern province are generally more highly leached than their younger counterparts in the southern province. Sixteen land units are identified as distinct from soil units. These units give cognizance to vegetation and topographical features as well as soils.
