Aeration, Phosphorous, And Lime Affect Nitrogen Mineralization In Imperfectly Drained Forest Soils, M. S. Bhangoo, D. J. Albritton, Eugene Shoulders

Journal of the Arkansas Academy of Science

Unamended, limed, and phosphorus-enriched Caddo, Beauregard, and Wrightsville silt loams (A1 horizon) were incubated for six months at room temperature under two moisture regimes. At field capacity, unamended soils lost 0.7% of organic matter and converted 166 ppm of organic nitrogen to inorganic forms. Ninety-five percent of the converted nitrogen was present as N₄-H or NO₃-N. Limed and phosphorus-treated soils at field capacity lost about 1.0% of organic matter and accumulated 191 to 201 ppm of inorganic nitrogen. Submerged soils lost very little organic matter and accumulated only 24 to 28 ppm of inorganic nitrogen. There was a loss of …

The Cork Oak, S R J Newton

Journal of the Department of Agriculture, Western Australia, Series 4

The oak or Querus genus embraces about 450 species which are generally restricted to the cool temperate regions of the Northern Hemisphere. Commercial cork is the over-abundant suberous tissue or bark from two rather unique members of the Querus genus, namely Q. suber and Q. occidentalis.

A lthough Western Australia has a most suitable climate for growing cork trees the potential of a local cork growing industry is severely limited.
