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...

Manganese absorption by barley roots

Creator:

Maas, E. V. (Eugene Vernon), 1936-

Abstract:

An investigation of Mn uptake by five-day-old excised barley roots revealed that a metabolically-mediated process was involved. In short-term experiments, the rate of Mn absorption was comparable to that of the macronutrient cations. Like other metabolically absorbed cations, the Mn absorption rate was a direct function of the ambient concentration...
