Abstract
In plot trials with wheat, maize and pearl millet, a 5-cm thick compact layer having a bulk density of 1.5-1.9 g/cm3 was prepared 10-15 or 25-30 cm deep in the soil and 32P was placed in a 1-cm layer below the compact layer to study root penetration. The presence of the compact layer 10-15 cm deep in the soil decreased root pentration and plant height, the decreases being greater with increasing bulk density. The compact layer at a depth of 25-30 cm was less detrimental to root penetration than at a depth of 10-15 cm. The use of 32P was unsuitable for quantitative determination of root penetration through compact layers in the soil
