soil compaction
Host: flue-cured tobacco (Nicotiana tabacum (flue-cured type)
L.)
Descriptor: Damage
Description: Fields with sandy topsoils may develop hard, compacted zones at or just beneath the plow layer. These compacted zones (often called plow-pans, tillage pans, or hardpans) develop when heavy implements are used on wet or recently plowed soil. The compacted layers become hard upon drying and may be detected by probing. Root growth is limited primarily to the upper topsoil and plants may wilt under slight moisture stress. Nutrient uptake, plant growth, and yields may be reduced. Use of implements such as subsoilers or chisel plows to break the compacted zone before transplanting may increase yields 5-20%, depending on the strength of pan development and adequacy of rainfall.
