A field experiment was conducted at Canwood, Saskatchewan to determine if annual applications of nitrogen (112 kg N ha?1) and sulphur (11 kg S ha?1) fertilizers to grass over 13 yr (1980 to 1992) could increase storage of total C (TC) and light fraction C (LFC) in a Dark Gray Chernozem soil. Hay was removed from the plots every year. The increase in mass of TC in the 0- to 30-cm soil depth from NS fertilizer was 3.88 Mg C ha?1. However, the increase in mass of LFC from NS was 9.50 Mg C ha?1, and most of the increase was found in the 0- to 5-cm soil depth.
