Hydrochars from Biosolids and Urban Wastes as Substitute Materials for Peat

Urban Farm DB summary

This study compared peat, hydrochars from biosolids (HSL) and urban wastes (HUW), and their 50% volume mixtures with peat, as potential substrates. Ryegrass was grown in these mixtures, and hydrophysical and biochemical properties were analyzed. Treatments with biosolids hydrochar (HSL) and its mixture with peat (PT + HSL) increased ryegrass dry weight production by 184% and 216% respectively, compared to peat.
