Forced aeration composing of coniferous bark

A forced aeration system of composting was used to accelerate the decomposition of 14m 3 piles of Sitka spruce bark ( Picea sitchensis) for 1 month. The aeration system was similar to the Rutgers system except that greater aeration was used in the first 3 days of composting. Bioassays with tomato pl...

Description
Summary:A forced aeration system of composting was used to accelerate the decomposition of 14m 3 piles of Sitka spruce bark ( Picea sitchensis) for 1 month. The aeration system was similar to the Rutgers system except that greater aeration was used in the first 3 days of composting. Bioassays with tomato plants ( Solanum lycopersicum) growing on such composted bark suggested that the phytotoxicity of raw bark was reduced by this process. The optimal conditions for decomposition were composting temperatures below 60°C, urea supplementation and milled bark.
