Strains of O. compressus which originate from Paros in southern Greece were the earliest flowering serradellas tested. They consistently produced amongst the highest seed yields, are relatively hard-seeded and are worthy of further investigation for deep sands and very acid soils in low rainfall areas. Monthly applications of nitrogenous fertilizer about doubled the herbage yields of serradella in winter.
Residual Value Of Rock Phosphate Fertilizers, J W. Bowden, Michael D A Bolland
Residual Value Of Rock Phosphate Fertilizers, J W. Bowden, Michael D A Bolland

The residual value of Christmas Island C-grade ore, 500 degrees C heated (calcined) C-grade ore (Calciphos), and superphosphate was measured in three experiments. Plant yield, and bicarbonate-soluble phosphorus extracted from the top 10 cm of soil were used to indicate the effectiveness of the four fertilizers. Using either of these indicators, superphosphate was the most effective fertilizer.
An Inventory And Condition Survey Of Rangelands In The Carnarvon Basin, Western Australia, A L. Payne, G F. Spencer, P J. Curry
An Inventory And Condition Survey Of Rangelands In The Carnarvon Basin, Western Australia, A L. Payne, G F. Spencer, P J. Curry
Technical Bulletins
The inventory and condition survey of rangelands in the Carnarvon Basin, undertaken by the Department of Agriculture and Food, Western Australia (DAFWA) between 1980 and 1982, describes and maps the natural resources of the region’s pastoral leasehold land. This survey report provides a baseline record of the existence and condition of the natural area’s resources, to assist with the planning and implementation of land management practices. The report identified and described the condition of soils, landforms, vegetation, habitat, ecosystems, and declared plants and animals. It also assessed the impact of pastoralism and made land management recommendations. The area surveyed covers …

The water-holding capacity of these soils, and their location in a low rainfall area combine to make them marginal for producing grain. In contrast to sowing wheat on ley pasture, mechanically fallowing the year before planting markedly improved grain yields by 1.3 to 4 times.
