Using Nutrition Effectively During Propagation
The benefit of incorporating controlled-release fertilizer (CRF) in the propagation media of woody stock from cuttings has been affirmed by extensive research over the last 2 decades, yet it is not universally adopted. This may be due to poor performance, in some grower evaluations, as a result of using inappropriate fertiliser formats, or application rates. Since trials on CRFs began, the use of multi-cell trays, and direct sticking into small tube pots, has become more common. These new techniques present extra challenges requiring special consideration. This paper outlines potential methods for achieving uniform distribution of the CRFs, in relatively small media volumes, at a rate that does not inhibit root development resulting from high initial salinity.
