Landform Mapping Of The Clarks River Alluvial System Using Lidar Dems, Benedict W. Ferguson

Scholars Week

The Clarks River is located in western Kentucky near the city of Benton. It travels through and weathers lacustrine or lake deposits as well as fluvial or river deposits. These deposits are also overlain by loess deposited from the last glacial maximum. Historically, people have taken advantage of these rich deposits for agriculture which has led to increased settlement. With increased settlement, the river has experienced alteration. The west fork of the Clarks River has been channelized while the east fork of the Clarks River has managed to remain un-channelized and has since been allowed to run relatively freely.

Mapping The Variability Of Soil Quality Indicators In Natural Versus Agricultural Ecosystems, Mary G. Derting Miss

Scholars Week

Traditionally, Kentucky agriculture has focused on crop production and soil fertility while overlooking soil quality and its dependence on land management type. This research attempted to reveal the importance of land management types and their individual effects on physical soil quality indicators. The second objective of this study was to show the variance of physical soil quality indicators across different land managements by using layered maps. Such visual representation of the data along with statistical analysis also showed which soil quality parameters are more sensitive to change in land management type. Land management types included three undisturbed grassland and undisturbed …

Over time, playing fields are monitored by overall appearance. However, pedestrian compaction is not evenly distributed throughout the entire surface.

Evaluating The Impact Of Natural And Agricultural Ecosystems On Soil Properties In Western Kentucky., Cody Masterson

Murray State Theses and Dissertations

The importance and capabilities of soil are often overlooked. It has an exceedingly complex ecosystem that is still not fully understood, but looking into soil properties can provide a clearer picture of what goes on below the surface. Understanding the influence of land covers and soil management allow for better understanding of how the soil ecosystem works which in return provides insight into how to create a more sustainable form of agriculture. Different ecosystems greatly impact soil properties. Soil physical properties are considered sensitive indicators of perturbation due to soil management practices and land covers. The four ecosystems that were …
