Sustainability of dryland cropping systems in the Wimmera region of Victoria / y Yvonne L. Postlethwaite.

Postlethwaite, Yvonne L., (Yvonne Lynette). January 1998 (has links)
Bibliography: p. 283-313. / xxxii, 313 p. : ill. (chiefly col.) ; 30 cm. / Title page, contents and abstract only. The complete thesis in print form is available from the University Library. / Two systems of dryland cropping, one conventional and one conservation, were studied on the same farm over a period of 10 and 14 years respectively. The conventional cropping system was based on cultivated fallow which served to manage and conserve water, nitrified organic matter and controlled weeds. Stubble was burnt prior to cultivation for the fallow phase, with pasture and cropping phases rotated. The conservation farming system was based on the absence of soil tillage, stubble retention, rotation of a variety of crops and chemical control of weeds. Water conservation was achieved through increased infiltration by improved soil structure, avoidance of compaction, reduced water runoff and reduced evaporation by stubble retention. Overall, the conventional farming system was proven to be unsustainable. The conservation system was sustainable in terms of productivity, profitability and effect on the environmental resources of soil and water. The growing of sorghum as a summer grass in the Wimmera was also found to be an opportunity for improving productivity, profitability and sustainability by controlling winter weeds. / Thesis (Ph.D.)--University of Adelaide, Dept. of Agronomy and Farming Systems, 1998

A locale of the cosmos : an epic of the Wimmera : exegesis and text

Rieth, Homer Manfred January 2006 (has links)
"This project has, for its central component, an epic poem, 'A locale of the cosmos'. The accompanying exegesis examines epic as an ancient, but continually evolving form. It argues that, as a contemporary example of the genre and, as a sustained poetic rumination on landscape and memory, 'A locale of the cosmos' represents a significant development within the modern tradition of autobiographical epic. In broader terms, 'A locale of the cosmos' privileges the landscape and history of a region of Australia, the Wimmera region of north-western Victoria and, in doing so, explores the cumulative effects of the physical environment as a site for sustained poetic treatment. The poem is, therefore, an epic of both historical narrative and philosophical reflection, giving meaning to and interpreting ideas of space, place and locale. "Furthermore, it explores, in particular, the psychological and spiritual effects of vast horizontal distances, created by a landscape in which endless plains and immense horizons form an analogue of the wider cosmos. The poem's themes, therefore, bear not only on the prominences of the visible locale, but also explore the salients of an interior world, a landscape of the mind to which the poetry gives shape and meaning." / Doctor of Philosophy

The floristic composition and regeneration characteristics of Buloke (Allocasuarina luehmannii) woodland of the Wimmera, Victoria

Macaulay, Lisa Ann January 2006 (has links)
"The pre-settlement distribution and character of Wimmera Buloke woodlands are described based on historical data including early parish plans. It is suggested the open structure of these woodlands was maintained by relatively frequent fire. The floristic composition of the most intact Wimmera Buloke woodland remnants was intensively surveyed. Five floristic communities are described based on computer-based analysis of species presence data. Eight 'pre-settlement Buloke woodland types' are described based on surface soil texture categories and average annual rainfall zones. Native daisies, chenopods and shrubs are components of the understory that differentiate the 'pre-settlement Buloke woodland types'. [...] A series of experiments was undertaken with the aim of determinig the factors responsible for the paucity of Allocasuarina luehmannii regeneration in remnant Wimmera bushland." / Master of Applied Science
