Abstract/Description

Changes of Soil Properties as Affected by Land Uses in Western Kentucky

Abstract

Soil properties can range widely over small areas and cropping systems. These differences can affect management decisions and overall fertility within fields. The objective of this study was to determine the impact of various land uses on the topsoil. Tobacco, corn, soybean, hemp, sod, and fallow fields were used in the study. Soil organic matter (SOM), bulk density, macroporosity, and soil pH were the specific properties sampled. To test these soil properties, we used disturbed and undisturbed soil samples. Bulk density and macroporosity were sampled from undisturbed soil to preserve porosity. SOM was gathered from disturbed soil and oven-dried for proper measurement. Each of the previous three samples was replicated three times for each field. A soil pH tester was used and replicated fifteen times for each field in the study. The results show the highest content of soil organic matter was found in tobacco one (T1) with the value 3.72 %. The lowest value of soil organic matter was in the tall hemp with 1.9%. hade bulk density range was much closer, with a cornfield (C2) having the highest value at 1.43 (g/cm³) and tobacco (T1) had the lowest value at 1.21 (g/cm³). The findings of this study will be beneficial for future farm management decisions in Western Kentucky.
