Abstract/Contents:"Compositing offers an opportunity to recycle food waste as a soil amendment. A three year growth trial was conducted to determine the fertilizer nitrogen (N) replacement value of food waste composts for cool season perennial grass production. Six composts were produced in a pilot-scale project with two composting methods (aerated static pile and aerated turned windrow). The aerated, turned windrow method stimulated "agitated bay" composting systems, which utilize routine mechanical agitation. Compost bulking agents included yard trimmings, yard trimmings + mixed paper waste, and wood waste + sawdust. Finished compost had Kjeldahl N concentrations ranging from 10 to 18 g N/kg. For the growth trial, compostes were incorporated into the top eight to 10 cm of sandy loam soil at application rates of approximately 155 Mg/ha (about 7 yd³ /1000ft²). Tall fescue (Festuca arundinacea Schreb. 'A.U. Triumph') was seeded after compost incorpiration, and was harvested repeatedly at a late vegitatative growth stage (April to November; approx. 35 days regrowth between harvests). Grass yield and grass N uptake did not respond to compost application during the first year. During the second and third years after application, composts were a consistent source of slow-release N. They supplied the fertilizer N equivalent of 0.70 kg N/ha/day over a 140-day period (April to August) in both years. The N supplied by the compost in the second and third year after application was valued at $0.70 to $1.90 per dry tonne (Mg) compost per year, using a fertilizer N cost of $1/Kg N. Food waste composts with signifigant slow-release N properties were produced with either the aerated static pile composting method or the aerated, turned windrow method. Composts with the higher N concentrations had higher fertilizer N replacement value. The slow release N supplied by food waste composts is ideally suited for urban lanscapes, where moderate, consistant rate of plant growth is highly desireable."
