P. australis transplants were first fertilised in situ on 16–17 March
2004,10weeks after planting, and then at 4–5 month intervals for two
years. Slow-release fertiliser (Osmocote® 5-month release) was used
with N only (33:0:0) with 33% nitrogen as urea, and Osmocote® P only
(0:18:0), 18% phosphorus as mono-calcium phosphate. Chelated iron
was added as FeEDTA: 12% Fe, with 200 g suspended in 1 L of seawater
(after Marba et al., 2008)
