Abstract

Understanding the dynamics of soil characteristics in different ecosystems is important in terms of sustainable agricultural land use. Four temperate ecosystems from Kentucky were used to study their impacts on various soil characteristics. Undisturbed and disturbed soil samples from a depth 0 to 7.5 cm were collected on September 8th, 2019, from tobacco, soybean, and pasture fields as well as wooded areas with four replications at each location. The tobacco field samples were collected in Breckenridge County, Kentucky; the soybean and wooded samples were collected in Christain County, Kentucky; and the pasture samples were collected in Harrison County, Kentucky. These fields have been used in continuous agriculture production using both conventional tillage and no-till. The pasture field has been utilized in a beef cattle rotation for approximately 15 years. The wooded area has been established for many years. The soil samples were analyzed for soil water retention, bulk density, porosity, soil organic matter, and soil pH. The data from this study will be described in the poster. The findings of this study will be beneficial because it could help landowners in their consideration when determining ways to manage their land. Not only will these results bring about new knowledge to our viewers, but they will also influence future decisions regarding agriculture management practices.

Keywords: bulk density, soil organic matter, soil water retention, acidity, porosity
