Abstract
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.
Of the few published normal nutrient ranges
for Proteaceae, none have shown to be relevant to commercial cut flower production.
This research reports on a strategy to develop leaf standard nutrient ranges for key
Proteaceae products.
Historical data of leaf analyses was collected from global sources,
and combined to define broad standard ranges.
Data for Leucospermum varieties is
presented here.
The results are intended as preliminary information to enable and
encourage 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.
