Granulated biosolids in turf
Summary
Chinese delegates inspecting granulated biosolids on turf
This project forms part of Sydney Water’s strategy to diversify its market for biosolids. It has been examining the fertiliser value and impacts on nutrient runoff characteristics of granulated biosolids surface applied to turf. Two rainfall simulations have been conducted on the experimental plots at CROA to measure treatment effects on runoff, as well as nutrient and pathogen transport. Detailed studies have also been performed adjacent to the plots to measure nitrogen mineralization rates from the granulated biosolids to improve understanding of how these products can be used to supply nitrogen to turf.
