Effective nutrition management combines strategies for balanced soil nutrient content and targeted plant nutrition. In commercial horticulture leaf samples are regularly sent for analysis of nutrient levels. The actual levels measured in a sample are compared against a known standard range for normal leaf nutrient content for that specific crop, and recommendations for fertiliser applications may be made to correct any deficiencies or imbalances in the plant. This project aims to develop leaf standard nutrient ranges for key wildflower products. In the first phase of the project historical data of leaf analyses will be collected and combined to define standard ranges. In the second phase any gaps or inconsistencies will be addressed through monthly leaf analyses of relevant crops. The results of this project further add to a broader understanding of key wildflower crops initiated by the Quality specifications profiles and built on in the Canopy Management project and the Farm Plus project.

Objective Summary

The project aims to establish normal ranges of leaf nutrient concentrations for Australian and South African native plants grown for commercial flower production. This will enable the industry to use regular leaf analysis as a tool in developing effective nutrition management plans to support healthy plant growth and provide high yields of good quality product. The 30 products highlighted in the RIRDC Quality Specifications manual will be the focus of this project.
