PHOSPHORUS NUTRITION OF LEUCADENDRON "SAFARI SUNSET" |
| Authors: | M. Prasad, D.J. Dennis |
| Abstract:
A range of available soil phosphorus concentrations was obtained by adding superphosphate to potting mixtures and field soil or by the application of amendments to field soil. Growth was good over a range of available phosphorus concentrations suggesting that Leucadendron was tolerant to high rates of applied phosphate. Growth was increased at the lower application rates in pots but not in the field. Available phosphorus was related to application rate but not to phosphorus uptake. Amendments reduced soil pH and phosphorus uptake but did not give a yield response. | |
