NY525/NY95025 - Improved Irrigation Fertiliser Management Strategies for Containerised Nursery Plants through Commercial Demonstrations and Further Research

This project consisted of several components conducted on the Far North Coast of NSW under Dr Huett’s supervision and in the Sydney metropolitan area by Dr Cresswell. The Sydney component also involved herbicide runoff studies. Major components of the project were demonstration of efficient management practices designed to reduce nutrient runoff and there were conducted on commercial nurseries. It was found the nurseries, particularly where plants are produced under cover, should consider capillary systems as alternatives to overhead irrigation. These systems when combined with a more stable nutrient supply offer substantial plant growth response.
