Evaluating the Impact of Livestock Type on Soil Properties in Kentucky

Project Abstract

Abstract

Soil health is a key factor in sustainable agriculture. It affects crop productivity, nutrient cycling, water quality, and ecosystem function. Livestock farming can change soil properties through grazing, trampling, and manure application. The effect depends on the type of livestock, stocking density, grazing intensity, and management practices. Moderate grazing can improve soil structure, increase organic carbon, and enhance water infiltration. Overgrazing can cause soil compaction, reduced porosity, erosion, and nutrient loss. Understanding these effects is important for sustainable land management. This study aims to examine the impact of different livestock systems on soil physical and chemical properties in western Kentucky. Five livestock types—horses, swine, beef cattle, sheep/goats, and poultry—will be studied. A control field with no livestock activity will be included for comparison. Soil samples will be collected at one depth. Disturbed samples will be used for chemical analysis, and undisturbed cores will be used to study physical properties. Laboratory analyses will measure bulk density, total porosity, macroporosity, water-holding capacity, field capacity, organic matter content, organic carbon, and pH. Data will be organized in Microsoft Excel. Descriptive and comparative statistics will be used to identify differences among livestock systems. The study is expected to show how different livestock affect soil health. It will identify which livestock systems maintain or improve soil quality and which may harm it. The results will help farmers and land managers choose practices that protect soil while supporting livestock productivity. The findings will be shared through a poster and oral presentation at Murray State Scholar’s Week. There may also be submission to the Kentucky Academy of Science and preparation of a manuscript for a peer-reviewed journal. This research will provide practical recommendations for sustainable livestock management. It will improve understanding of livestock-soil interactions and support long-term soil conservation and agricultural sustainability in Kentucky.
