Clay mineralogy and related chemical properties of soils formed on Mazama pumice

Creator:

Chichester, Frederick Wesley

Abstract:

A sequence of soil profiles was sampled along a climate-vegetation transect on the dated Mazama pumice fall in central Oregon. The <2 μ size fraction from each sample was characterized with respect to the relative significance of amorphous and crystalline components, and the individual minerals of the latter group were...

Microbial and biochemical dynamics of ectomycorrhizal mat and non-mat forest soils

Creator:

Kluber, Laurel A.

Abstract:

Dense hyphal mats formed by ectomycorrhizal (EcM) fungi are prominent features in Douglas-fir (Pseudotsuga menziesii) forest soils and have been estimated to cover up to 40% of the forest floor in some stands. Although previous studies have examined various aspects of EcM fungi, little is known about their associated microbial...
