Abstract

Over time, managing different crops has caused soils to change their characteristics. The study includes a comparison between soils found in five different locations. Using the bulk density, water holding capacity, soil organic matter, soil pH, soil water content at field capacity, and soil porosity, this study aims to distinguish how continuously using the same cropping systems will affect soils over an extended period of time. Soil samples were collected from Christian County, Kentucky, Caldwell County, Kentucky, Calloway County, Kentucky, and Madison County, Illinois on August 29th 2017. The soil samples collected include silt loams and sandy silt loams that are in use for horse pasture, raising dark tobacco, conservation reserve program, gardening, and a park. From each location, three undisturbed soil samples and three disturbed samples were taken from the depth interval of 0 to 6.5 cm. The results show that the growth of different plants species can alter soil physical and chemical conditions under different cropping systems. The detail results and further discussion of this study will described in the poster. In general, the change of soil characteristics due to continuous cultivation was positive and negative depending on the type of land cover.

Keywords: Acidity, Bulk Density, Illinois, Kentucky, Organic Matter, Soil Water
