Studies were conducted to determine the horticultural suitability of composted paper mill biosolids (PMB) as a replacement for peat. The first objective was to determine the physio-chemical and biological properties of composted PMB as affected by source (Clarendon and Miramachi) and processing (dehydrating, screening and blending with peat). Except raw compost, all compost treatments were mixed with 0, 50 and 75% peat (v/v) to generate growing media blends. Physio-chemical parameters indicated mixes were within recommended ranges, except for high ash content and bulk density. Biological properties, with the exception of dissolved organic carbon, showed that treatments were mature. Screening and dehydrating had a small effect on the physio-chemical and biological properties, when compared with amending with peat. Greenhouse studies demonstrated combining Clarendon and Miramachi with 50% peat, improved lettuce and tomato root and shoot growth compared to compost alone, while another PMB compost (Louisiana Pacific) did well without being mixed with peat.
