Title : Application of char products improves urban soil quality
Journal : Soil Use and Management
Comment : They assessed the effect of applying coarse and fine char material on the quality of four different types of soil-based root-zone mixes typically used for turfgrass and general landscaping in Singapore. The addition of char (both coarse and fine) significantly enhanced the carbon content of the mixes, with the largest increase being associated with the 50% and 75% additions. Soil nutrients (total N, extractable P, K, Ca and Mg) and mean weight diameter of aggregates were also significantly increased following the application of char.
