Abstract

Manure or compost application can increase carbon (C) sequestration in the soil since these organic sources contain significant amounts of C, which is a major constituent of soil organic matter. An experiment was conducted from 1992 to 1996 to evaluate the effects of annual or biennial N- and P-based manure or composted manure application on soil C sequestration. Fertilized and unfertilized checks were also included. About 25% of applied manure C and 36% of applied compost C remained in the surface (0-6 inch) soil after four years of application, indicating greater C sequestration with composted than noncomposted manure. Soil C in the 6 to 12 inch soil was unaffected by the applied manure, compost, and fertilizer.
