| Abstract:
Concern by environmental groups in the U.K. has led, over the past 3 years, to a renewed assessment of materials suitable as container media for plants. In this paper Peat, Coir (Coconut fibre waste) and Woodfibre ("Hortifibre", France) were used as basic ingredients, with the addition of composted sewage, or the organic fraction of domestic refuse - fresh, partially composted, or fully composted and matured. At 30% by volume inclusion only slight depression of growth was experienced with various "bedding" plants although only the composted sewage and the fully mature refuse compost could realistically be used as commercial ingredients. Unfortunately public prejudice to such materials currently precludes their immediate use. | |
