Temperate Pasture Sustainability Key Program: an overview

Abstract

This special edition of the Australian Journal of Experimental Agriculture presents papers from work undertaken as part of the Temperate Pasture Sustainability Key Program (TPSKP; see Fig. 1), and presented at a workshop in Sydney in November 1997.

TPSKP was initiated by Meat and Livestock Australia (MLA). The Land and Water Resources Research and Development Corporation, the International Wool Secretariat and the Murray Darling Basin Commission were joint funders of some of the individual projects.

Most projects were carried out on private properties, and many had producer groups associated with the sites to provide input into treatment selections as well as management guidance and support. This substantial producer input was provided free to the program.

The success of TPSKP relied heavily on physical and financial support from State departments of agriculture and conservation, CSIRO and universities, and also on the enthusiasm of these groups to work collaboratively across the 4 south-eastern states. One of the key results of this cooperation was the development of a set of experimental protocols so that measurements taken anywhere in TPSKP could be directly compared.

TPSKP aimed to develop the principles for manipulating pasture composition to make grazing systems more productive and sustainable. The program priorities were to: (i) determine by survey the attitudes of producers to grazing management and identify the characteristics of those producers most likely to adopt the program results; (ii) demonstrate by June 1996 that potentially responsive perennial grass-based pastures could be upgraded using grazing management to become a ‘desirable’ pasture for animal production and sustainability; (iii) demonstrate by June 1996 that newly sown perennial grass-based pastures could be maintained in a desirable condition using grazing management; (iv) determine the critical factors responsible for the capacity of perennial grasses to persist, respond to drought, and ameliorate land degradation; (v) develop producers’ skills in pasture species identification, pasture and animal assessment, and feed budgeting, both to enhance their existing management, and to ‘prime’ them for the outputs from TPSKP; (vi) to demonstrate (in phase 2) that improvements in pasture composition and grazing management can have both economic and environmental benefits.
