the 5th International Conference on Precision Agriculture* was held in Bloomington, Minnesota from July 16 - 19, 2000. This conference brought together 698 delegates from around the world including representatives from commercial companies, researchers, farm managers, consultants and growers. The conference highlighted that an expanding number of companies are becoming involved in the development and application of technologies specifically for use in site-specific management systems. Researchers are using this technology to develop more economicalIy and environmentally sound farming systems for an increasing number of crops worldwide. We presented papers on establishing an opportunity index for precision agriculture and the variable-rate application of nitrogen fertiliser to Australian cotton fields, which are included as Appendices I and 2 respectively. Full proceedings from the conference are now available.
