Food and Yard Waste Compost as a Nutrient Source for Corn Production

Garnett, Angela 14 March 2012 (has links)
Utilizing food and yard waste (FYW) compost for plant production requires determination of application rates that support crop production, improve soil properties and avoid excessive nutrient build-up. An 88 day incubation experiment showed 12 t ha-1 FYW compost to contribute 3.6 kg M3P ha-1 and 0.3 kg mineral N ha-1, 24 t ha-1 supplied 15.1 kg M3P ha-1 and 0.7 kg N ha-1 and 36 t ha-1 gave 39.5 kg M3P ha-1 and 1.2 kg N ha-1 to Pugwash series coarse, loamy soil. A field study showed FYW compost yielded higher P concentrations in grain and stover but lower grain yields than fertilizer. In the residual year, compost treatment yields didn’t decrease and concentrations and amounts of P and N increased. This FYW compost applied to corn at 24 t ha-1 with an N fertilizer can yield similarly to fertilizers only, removing greater amounts of P in grain and stover.
