Fertilizer nitrogen (N) management and other cultural practices used in reclamation can have a significant effect on the successful revegetation of mined lands. Repeated fertilization of revegetated lands creates management and economic concerns. Nitrogen fertilizer was broadcast at 67 kg ha-1 yr-1 for 4 years and at 268 ha-1 for 1 year on revegetated mined land to evaluate N management effects on forage production. Seeded grass production over 5 years did not exhibit consistent increases for the single N fertilizer application compared to the 4 annual applications. Although the single, higher N fertilization treatment only produced significantly greater forage in 3 instances compared to the lower annual fertilization treatment, it would result in a significant savings in application costs. Seeded grass production was higher and annual forb production lower when established using a standing grain stubble mulch compared to a crimped straw mulch. A single, higher application rate of nitrogen and a stubble mulch are recommended because of their production, management, and economic benefits.
