Seedling Response In A Greenhouse To Four Rates Of Old And New Paper Mill Sludge, Jimmie L. Yeiser
Seedling Response In A Greenhouse To Four Rates Of Old And New Paper Mill Sludge, Jimmie L. Yeiser
Journal of the Arkansas Academy of Science
Four rates (0, 36, 75, and 11 2 DT/A)of both old and new pulp-mill sludges were tested in a greenhouse for impact on survival and growth of seedlings of loblolly pine (Pinus taeda L). After one growing season no meaningful differences were detected for seedling survival and growth, number off lushes, and decomposition rate for old and new sludges regardless of rate. Seedling foliage showed increases in Mg and Ca and sludges exhibited high pH and increased salinity.

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 …
