The effects of zinc and phosphorus treatments on five different
plant species were investigated in a greenhouse experiment. A
second greenhouse experiment extended these investigations in sweet
corn over a broad range of phosphorus treatments with and without
adequate zinc nutrition to study phosphorus induced zinc deficiency.
The plant responses...

The morphology and genesis of soils of the Willamette series
and of some Willamette-associated soils and their relationships to
geomorphic surfaces were studied in an area near McCoy, Polk
County, Oregon. Influences of regional extent, such as climate and
parent material, were related to the soils and landforms. The soils...

We are concerned here with well-posed problems for the partial differential equation uₜ(x, t) + yMuₜ(x, t) + Lu(x, t) = f(x, t) containing the elliptic differential operator M of order 2m and the differential operator L of order ≤2m. Hilbert space methods are used to formulate and solve an...
