Sewage sludge is a waste product produced from municipal water treatment and is composed primarily ofx000D
dewatered microbial biomass from the anaerobic digester. Composted biosolids improve soil fertility andx000D
structure while providing disease suppression for root and foliar pathogens. Additions of biosolids to plantsx000D
grown in greenhouse and field can help to naturally suppress disease infiltration by the addition of antagonisticx000D
organisms. The slow mineralization of biosolids fertilizers provides long-term nutrient release which isx000D
beneficial for the environment. If these amendments are applied to soils at an appropriate rate they could be ax000D
safe and efficient source of organic fertilizer. Turfgrass is grown as a perennial crop that can create completex000D
ground cover and has a rather high root to shoot ratio. Turfgrasses grown for maintained areas require highx000D
amounts of fertilizer, especially nitrogen, and can benefit from an increase organic matter as many turfgrassesx000D
are grown on sandy soils. Expansion into this industry is essential for reducing the amount of sewage sludgex000D
sent to landfill where its nutrient rich qualities are underutilized. Turning this waste product into a viablex000D
source of nutrients and microbial communities has been done by several companies including the Ontariox000D
based company named Lystek. The objectives of this research are to determine the suitability of use inx000D
non-food crops such as turfgrass production and ornamental floriculture and help to understand how biosolidsx000D
change soil and plant root health.
