This project was a demonstration of the effects of compost on the growth of hardwood and softwood tree seedlings. There is interest in identifying cost-effective means to improve the revegetation of severely disturbed sites. The standard method of revegetating these types of sites generally involves seeding and/or planting, fertilizing, and mulching. For erosion control and revegetation, grass seed, pine seedlings, chemical fertilizers, straw and machine-blown pulp mulches are commonly used. This study tested the hypothesis that the use of composted products from organic materials has practical uses in forestry related applications and has the potential to improve the growth of tree seedlings in severely degraded soils. During December 1994, a group of tests were initiated on three damaged (e.g. compacted or severely eroded) sites to compare a standard straw mulch to three different composts used as mulches.
