Foliar nutrition survey and management implications for young Blue gum plantations
- Client: MBAC Consulting Group
Using standard foliar protocols, foliar sampling was undertaken of E. globulus (Blue gum) plantations throughout Tasmania, Victoria, South-Australia and Western Australia to assess nutritional health of plantations, and to identify which plantations could economically benefit from supplementary fertiliser applications, and those which would not yield a return on investment. Nutritional health was assessed by a number of methods including:
- visual symptomatic analysis
- laboratory analysis
- threshold analysis
- regression analysis
- discussion on importance of plant nutrition
- review of plant nutrition practice
- recommendations for remedial nutrient applications and estimated costs
Plantations temporarily unmanaged due to liquidation of the management company required evaluation to determine the value of additional investment to maintain and improve investor returns.
Verterra developed a field assessment procedure, supported by laboratory analysis of foliar nutrition, to rapidly and efficiently provide a quantitative assessment of expected plantation response to fertiliser application. The approach merged forest economics into a simple prescription for the plantations assessed. The approach enabled assessment of 126 sampling points over 30 properties and three states in 10 days.
Benefit to Client:
This study formed part of an expert witness report that provided the client with a rapid assessment of a cross section of the subject plantations, and an overview of overall estate nutritional health to support evaluation of both prior management effectiveness, and potential to economically improve future productivity.
