Trial 87WH51
Location: Wongan Hills Research Station.
This trial was put onto a site adjacent to Mel Mason's source of nitrogen trial and the CSIRO, 15 N plots to provide some explanation of the results from the limited treatments in those trials. They were designed to monitor soil/fertiliser nitrogen transformations with time. Unfortunately the site of this trial was variable. The end most similar to the other trials was deeper and sandier and stored less water than the other and where crop growth was far better.

Natural resources published reports
Kununurra Region
3rd edition
A small experimental farm was first established on the Ord River in 1941. This farm was relocated in 1945 to what is now known as the Frank Wise Institute of Tropical Agriculture.
The first stage of the Irrigation Scheme which included the Diversion dam was completed by 1963 and by 1966, 31 irrigated farms had been established.
In 1967 the second stage was commenced and by 1972 the main dam had been completed.
Cotton was the major crop until 1974. In the wet season of that year 3642 hectares was devoted to cotton. Various crops such …

Serradella Prospects At Esperance, Michael D A Bolland
Serradella Prospects At Esperance, Michael D A Bolland
Journal of the Department of Agriculture, Western Australia, Series 4
Yellow serradells is a promising introduced annual legume suitable for some of Western Australia's well drained sandy acid soils where other pasture legumes failto persist.
In the Esperance area serradella grows siccessfully on some sandy soils more than 0.5 metres deep. I develops deep roots rapidly - up to three times deeper than subterranean clover - and this is probably the main reason for its persistance.
At present only two late maturing, registered serradella cultivars are available to farmers in southern Australia. This article describes research at Esperance to delect earlier flowering cultivars for persistence in areas with less than …

Communication Networks And The Adoption Of Three Farn Practices, P. W. Fry, F. K. Goss
All other publications
The report commences with a discussion of the diffusion and adoption model, and illustrates some of the research observations and practical outcomes that have emerged in recent years, An overview of social network research is presented as a means of understanding communication exchanges and providing data relevant to the diffusion debate.

Draining A Saline Seep, W J. Burdass
Draining A Saline Seep, W J. Burdass
Journal of the Department of Agriculture, Western Australia, Series 4
Sub-surface drains have dried out a salty seep on farm land in the Katanning district. Capeweed and clovers are now growing on more than three-quarters of the land that was previously bare or carried only patchy sea barley grass.
The drains are still running water after five years. The salt content of the surface soil has been reduced markedly and the salt content of the effluent water is decreasing.
However, to complete the reclamation, further drains will be necessary. Both existing and any new drains will have to be flushed periodically because blockages of pipes cause problems.

A Land Resource Survey Of The Fall Point Coastline, Broome, W.A., P A. Hesp, P J. Curry
Resource management technical reports
The purpose of this study was to find a suitable location for a bird observatory and provide adequate coastal land resource data for the area. The main selection criteria and conditions were: the location was closely adjacent to major wader roosting and feeding sites; all-seasons access was required; the location provided a site of around 2 1/2 hectares to provide space for one or more buildings, camp ground and associated facilities ; anticipated access tracks, site developments and levels of use.

Hillside Seepages, R A. Nulsen
Hillside Seepages, R A. Nulsen
Journal of the Department of Agriculture, Western Australia, Series 4
'Hillside seepage' is a local, descriptive term applied to almost any wet patch occurring out of the valley bottom. Depending on their surface appearances, 'hillside seepages' are described as 'springs', 'soaks', 'wet patches', or seeps.
Whatever they are called, seeps can cause problems. The land in the seep is wet, unworkable and non-productive. If the seep is saline and the water flows downhill, further land is lost from production, bared and subject to erosion. Even small seeps, while not affecting much land, break up a paddock and complicate the working pattern for tillage and harvest.
Sub-Surface Drainage Methods For Salinity Control, P R. George
Sub-Surface Drainage Methods For Salinity Control, P R. George
Journal of the Department of Agriculture, Western Australia, Series 4
Sub-surface drainage can control waterlogging and salinity of arable land by removing excess groundwater.
There are two broad types of sub-surface drainage: interception drainage and relief drainage.
The cost of drainage will depend on the specific design for the site. For relief drains the prime determinate of cost will be the required spacing. In general, clay soils of low permeability or seepage areas will need narrower spacings and will be harder and more expensive to reclaim than sands or areas only needing drainage of local water.
