By contrast, phosphorus leaf content was largely unaffected by biochar additions (5.5 to 6 g kg -1 ) while potassium concentrations, while healthy (>30 g kg -1 ), showed a trend whereby the high KAR 1 biochar increased potassium content in leaf tissues (up to 50 g kg -1 at 30% biochar) more than other treatments (30 to 35 g kg -1 ).
