Creator:: Swanston, Christopher W.
Abstract:: Application of N fertilizer is a common forest management practice in the Pacific Northwest, yet the long-term influence of fertilization on forest soil properties is not well known. Although elevated N often increases mineralization of C and N from labile organic matter, negative effects have been documented in recalcitrant organic...
Resource Type:: Dissertation

Creator:: Sidle, Roy C.
Abstract:: Surface erosion can be initiated by forest practices such as timber harvest, road construction, and site preparation. A variety of management and control measures can help reduce this erosion. Surface erosion is generated by soil and operational conditions that are conducive to or cause disturbance and compaction. By using good...

Creator:: Chen, Hua
Abstract:: Controls of substrate quality, temperature, and moisture on woody root decomposition in the Pacific Northwest were explored using chronosequences, time series, laboratory incubations, and simulation modeling approaches at three sites: Cascade Head (CAH), H. J. Andrews (HJA), and Pringle Falls Experimental Forests (PRF). In the chronosequence study, a structural component-oriented...

Creator:: O'Dell, Thomas E.
Abstract:: We investigated the root endophytic fungi of lupine using four approaches: (1) occurrence of fungal colonization in field-collected roots; (2) growth response of L. latifolius to inoculation with two types of fungi; (3) structure of root colonizations of Pinus and Lupinus by Phialocephala fortinii, a septate endophytic fungus of lupine;...

Creator:: Pikul, Joseph Lawrence
Abstract:: Freeze/thaw cycles are numerous in agricultural soils of the Pacific Northwest. Potential loss of soil by erosion is high whenever a soil thaws from the surface creating a saturated soil overlying an impermeable frozen layer. Field studies were conducted to investigate the effect of surface residue on soil freezing. Residue...
