Some Statistical Analyses Of The Climate Of Nacogdoches, Texas For Applications In Natural Resources Management, Alexander Sayok
Some Statistical Analyses Of The Climate Of Nacogdoches, Texas For Applications In Natural Resources Management, Alexander Sayok
Electronic Theses and Dissertations
Analyses of a variety of climatic variables generated from 80 years (1901-80) of daily precipitation and temperature data collected by the National Weather Service showed that Nacogdoches is characterized by a humid subtropical climate with an average annual precipitation and temperature of 45.96 inches and 65.5°F, respectively. The summer is warm and dry with mean maximum temperature of 91.6°F while winter is mild with mean minimum temperature of 38°F. There were no statistical differences between mean annual temperature and precipitation on the 1951-80 and 1901-80 periods or between any 2 normal periods. Rain days occurred once in every 4 days …
A Demonstration Of Cartographic Modeling For Evaluating Natural Resources, Olufemi Amos Olaleye
A Demonstration Of Cartographic Modeling For Evaluating Natural Resources, Olufemi Amos Olaleye
Electronic Theses and Dissertations
Cartographic modeling was used to evaluate the natural resources of the Angelina National Forest in East Texas. With the aid of the Map Analysis Package, three models were developed to evaluate historic changes, project future trends and to determine the proximity of resource to a specific location. Accuracies of results were determined at two different scales. MAP estimates at the smaller scales were about 92% and about 98% at the larger scale. Boundary cells were found to be important in improving accuracies of MAP estimates at the smaller scale. The performance of a representative low-cost grid-based system in building cartographic …
The Effects Of Nitrogen And Phosphorus Fertilizer On A Young Loblolly Pine Plantation On Lignite Mine Spoil In East Texas, Martin Andrew Shupe
The Effects Of Nitrogen And Phosphorus Fertilizer On A Young Loblolly Pine Plantation On Lignite Mine Spoil In East Texas, Martin Andrew Shupe
Electronic Theses and Dissertations
Five levels of nitrogen fertilizer combined with three levels of phosphorus fertilizer were tested in a two year-old loblolly pine plantation on a lignite mine spoil in East Texas. Growth parameters, foliar and spoil nitrogen and phosphorus concentrations were measured after two growing seasons. Nitrogen increased diameter growth during the first year, and foliar nitrogen increased with increasing fertilizer rates for both years. Phosphorus increased height during the first year and over both years combined and also increased diameter during the second year and over both years combined. Foliar phosphorus was increased by nitrogen in the first year. Spoil phosphorus …
