Historical data on stocking rates and supplementary feed used on the 321 ha farm are given for the years 1970 to,l975. During this period major changes in winter grazing management practices were adopted. Management changes and reasons for thim are described and cost of and labour advantages of these changes; associated with a reduction of supplementary feed, are outlined: It is concluded that increases in stocking rates do not necessarily increase profit since in some instances they cause an increase in supplememary feeding. It is also concluded that the farm could winter l8 stock units/ha provided buying and selling policies were correctly timed and management systems used that can control intakes to the level desired.

Public concern for the way land resources are used has led to the introduction of legislation in several Australian States requiring the demonstration of sustainable use of the pastoral resource. However, no practical system of appraisal of sustainability in grazing management systems exists. The common situation facing decision-makers at policy and enterprise levels is one of inadequate, unobtainable or inappropriate data, or systematic indeterminacy. This necessitates erring on the side of caution, through an adaptive integrated approach to decision-making. Such an approach requires: (i) an understanding of the key processes that govern the interactions between livestock, plants, and heterogeneous landscape systems; (ii) the identification of indicators of potential problems in these systems at spatial and temporal scales relevant to human use and management; and (iii) the availability of effective tools to evaluate management options in terms of their risks to the sustainability of the grazing land resource, and the profitability of production. This paper describes a decision support approach to improving our understanding of the complexities of grazing management systems. The paper first proposes an integrated framework for a decision support system (DSS) for evaluating the sustainability of grazing management in terms of the risk of changes to the vegetation and soil resource, and the profitability of production. It then examines an application of a DSS approach, called Landassess DSS, to the tropical woodlands in northern Australia, and discusses the broader implications for sustainable management of extensive native pasture livestock production systems.

Poor performance of white clover in the current climate of innovation farm management practices has become problematical, particularly within the dairy industry. There are as many grazing management systems as there are farmers and management guidelines can only be broad generalisations at best, with little interpretive value in the face of the multitude of options available and variables recognised and unrecognised. The principles of plant growth are used to interpret grazing management strategies in order for farmers to have greater understanding of their pastures and determine for themselves what the expectations and outcomes of various management strategies may be. This is of greater relevance to the dairy industry where innovative changes (pasture covers, grass cultivars, pasture renewal and establishment techniques, fertiliser N) can combine to produce a 'clover unfriendly environment'. Keywords: competition, fertiliser N, grazing management, light, management systems, plant growth, protection, space, white clover.
