Fig. 1. Effects of inorganic fertilizer treatments on clipping yields. Error bars represent standard error (n = 18). Dashed vertical lines represent dates of compost topdressing applications. Means are averaged across compost topdressing treatments. N fertilizer applied in 1997 for the low (LR), moderate (MR), and high (HR) rate treatments were 96, 192, and 394 kg N ha^-1, respectively. N fertilizer applied in 1998 for the LR, MR, and HR treatments were 48, 96, and 192 kg N ha^-1, respectively
