Jurgensen, M. F.; Larsen, M. J.; Harvey, A. E. 1979. Forest soil biology-timber harvesting relationships: a perspective. Gen. Tech. Rep. INT-GTR-69. Ogden, UT: U.S. Department of Agriculture, Forest Service, Intermountain Forest and Range Experiment Station. 12 p.

Timber harvesting has a pronounced effect on the soil microflora by wood removal and changing properties. This paper gives a perspective on soil biology-harvesting relationships with emphasis on the northern Rocky Mountain region. Of special significance to forest management operations are the effects of soil micro-organisms on: the availability of soil nutrients, particularly nitrogen; the decay of woody plant material; and tree disease incidence. At present, no widespread detrimental impact on site quality in the northern Rocky Mountain region can be directly attributed to harvesting effects on the soil microflora.

Keywords: timber harvesting, soil micro-organisms, nutrient cycling, nitrogen fixation, nitrification, denitrification, mycorrhizae, disease, fire, residues, decay, mineralization, rhizosphere
