This study of cut and fill slopes, some untreated, some hydroseeded in the conventional, some hydroseeded with different sludge dosages, and another only with sewage sludge and seeds with no slurry mix to look at the impacts on erosion and vegetable growth. After two vegetation cycles, erosion on an untreated control plot was on average 2.2 times lower in the cut slopes and 3.5 times in the fill slopes compared to plots hydroseeded with sewage sludge. Where sewage sludge and seeds were applied without the slurry mix the performance was similar to the rest of the hydroseeded plots that had received sewage sludge with the slurry mix.
