Land Resource Evaluation - Ninety Mile Tank Report on Trials Conducted 1968, 1969 and 1970 By Plant Research Division and Wheat and Sheep Division

In the late 1920\u27s the seven million acres of virgin land between Hyden and Salmon Gums were considered for settlement under the 3,500 farms scheme because it constituted practically the only large area of wheat lands in a suitable climatic zone not then settled in Australia (Teakle 1939). At that time the sandy scrubplain soils were more a liability than an asset because methods of profitably farming the light soils had not then been evolved. These useless scrubplains merely increased the distances between patches of\u27 more f\u27ertile soils. The scheme for settlement was based mainly on the potential of\u27 the heavy woodland soils with limited use made of\u27 the clay based mallee soils on which yields quickly dropped off after a small number of cereal crops (which more recent experience suggests was simply due to nitrogen deficiency). The woodland soils constitute only about 30 per cent of\u27 the total area. One third of the area of woodland soils was considered to be unsuitable for normal cropping due to excess soil salt. Despite the fact that only about 25 per cent of the total area was considered sound for intensive cereal cropping and an additional 20 per cent for extensive grazing, Teakle concluded that there seemed no reason from the standpoint of soils why settlement should not spread across the area in question should there be an economic urge for increased wheat and wool production after consolidation in settled areas

Sheep liver copper levels

Introduction. Our knowledge, and consequently our advise to farmers on the needs for copper fertilizers in the wheatbelt have been largely based on thoses of plants - cereals in particular. For one thing, definitive experimentation is easier with cereals than sheep. Discussion. Interpretation. Appendix

Lucerne establishment on the West Midland sandplain

WEST of Dandaragan and the Midland line from Watheroo to Mingenew there are four million acres of scrubplain commonly called the Western Sandplain. All virgin soils in this region are acutely nitrogen deficient so that the agricultural future of the region depends on how successfully legumes are grown
