| Abstract: | Semi-hardwood cuttings of Ligustrum japonicum Thunb. and Juniperus conferta Parl. were propagated in sand or sand : peat (1 : 1 v/v) and top-dressed with osmocote controlled-release fertilizers at various rates. Soluble salts, NO?3, P and K leaching through media was greater in sand, especially with osmocote 14-14-14. Loss of P and K in both media was not as rapid as the loss of NO?3. The pH of leachate from sand : peat was significantly less than that from sand. The 18-6-12 osmocote provided steady nutrient release in both media. |
