Serradella, Subterranean Clover And Medic Research, Esperance, Western Australia, Michael D A Bolland
Technical Bulletins
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
Technical Bulletins
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
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 …

Surface Drainage Trial., Department Of Agriculture, Western Australia.
Experimental Summaries - Plant Research
Trial 86V1
Location: Vasse Research Station.
The aim of this experiment was to quantify the response of annual pastures to improved surface drainage by laser levelling and from the pasture response data determine the cost.
