The inherent productivity of many fine-textured soils depends on timely extraction of water stored deep in the profile. Growth of crop roots and their ability to extract water are of central importance to efficient utilization of these soil resources. We observed the rate at which the soil volume was explored and water was extracted by cotton (Gossypium hirsutum L. 'GP3774') roots in a fine-textured soil in a subhumid environment. Measurements of root growth and water extraction were made for 2 yr in a 2.3 m deep weighing lysimeter, 3.0 m2 in area and containing an intact core of a Frio tax-adjuct silty clay loam (fine, montmorillonitic, thermic
