Abstract/Description

Soil Characteristics of the No-Till Systems in Kentucky

Hutson School of Agriculture, Murray State University

Previous research shows no-till farming has improved soil characteristics by preventing soil erosion and adding soil organic matter. Therefore, this study was conducted to determine the impact of no-till systems at different durations on soil properties, such as soil water retention, bulk density, porosity, soil organic matter and the level of acidity. Soil samples were collected from a 5 yrs, 10 yrs, 15 yrs, and 20 yrs of no-till systems in Calloway and Graves counties of western Kentucky. All of these fields were under a corn and soybean crop rotation. As a reference, a wood ecosystem of 50 years was used to see the changes of soil characteristics between undisturbed ecosystem (forest) and fields. There were 15 undisturbed and 15 composited disturbed soil samples from topsoil used for the analysis. The detailed data will be explained in the poster. The finding of this research will not only show the value of no-till systems, but also provides the importance of short-term (1-5 years) and long-term (more than 5 years) continued no-till practices.

Key Words: Acidity, Bulk Density, Kentucky, Porosity, Soil Organic Matter
