ALTERNATIVES TO PEAT AS CONTAINER MEDIA ; ORGANIC RESOURCES IN THE UK. |
| Author: | D.C. Cull |
| Abstract:
Since 1977 a number of organic waste materials have been tested at Bath as alternatives to peat as container media. Work on digested sewage sludge and separated animal fibre is presented. Nine large-scale bulky organic wastes in the UK are reviewed. Their physico-chemical properties and 'economic' properties, such as cost, availability, location of supplies, uniformity and competitive demand, are examined. Not one stands out as the alternative to peat in the UK; substrates will gradually diversify to encompass a number of materials as pure substrates (bark, leaf mould, separated animal fibre), or as ingredients in mixtures (sewage sludge, municipal compost, spent mushroom compost). | |
