Effect of sampling time and leaf position on leaf nutrient composition of Protea 'Pink Ice'



Effect of sampling time and leaf position on leaf nutrient composition of Protea 'Pink Ice'



Australian Journal of Experimental Agriculture 35(2): 275-283



Seasonal fluctuations in the concentrations of 12 nutrients were assessed over 3 years for Protea Pink Ice in 3 plantings in the Mount Lofty Ranges of South Australia. Nutrient concentrations in the youngest fully expanded leaves (YFEL) generally showed strong seasonal trends, reflecting seasonal vegetative and flowering patterns, During May-Aug. and Dec.-Feb., YFEL N, P, K, Ca, Na, S, Cu, Zn, Mn and Fe concentrations were relatively stable, making these suitable times for sampling.
