Abstract/Description
Linking Soil Compaction Levels and Carbon Content in Various Agricultural Fields
Dakota C. Tate, I.P. Handayani, N. Musunuru Hutson School of Agriculture, Murray State University, KY, USA
Abstract
Soil compaction and the content of soil carbon control crop productions. Soil compaction levels affect the growth of plant roots as well as the soil aeration. Carbon content provides the food and energy for soil microorganisms which can improve biological-chemical conditions of the growing media and plant health. This research was conducted to determine the impacts of common agricultural management practices on soil compaction as measured by penetrometer and bulk density; and soil C content as tested using loss on ignition (LOI) method. Soil samples were collected from various farming systems in Calloway County, Kentucky and Jefferson County in Illinois at the depths of 7.5 cm and 15 cm. Forest or wood areas were used as references for comparing between undisturbed and disturbed ecosystems. In addition to soil compaction and total carbon measurements, soil color, soil water holding capacity, soil water content at field capacity, macro-porosity and aggregate stability were also determined. The data was analyzed using ANOVA one-way analysis with LSD test at 5% of level of significance to observe the significant difference among the fields and depth. The findings of this research will contribute to the knowledge of the dynamics of soil health indicators in agricultural ecosystems under silt- and clay loam soils. The detailed results will be presented during the conference.
