Tobacco is probably more adversely affected by soil compaction than, the other crops grown in Kentucky. ThIs Is due to the characteristIcs of the plant and the unusual cultural practIces under which it is grown.
Soil compaction increases soil density while reducing pore space and root penetration. The reduced pore space reduces the aeration of the soil, which reduces tobacco growth especially during wet periods. The effects of soil compaction on tobacco are due to both impedance of root growth and lack of aeration.
