Summary

Soil heterogeneity induced by oil palm trees was investigated in the forest zone of western Nigeria. Surface and subsoil samples taken from adjacent to the palm tree showed lower bulk density, higher soil moisture retention, higher organic matter content and nutrient status than the surrounding soil.

Maize plants grown on the palm site soil showed better growth, nutrient status and yield. The palm tree effect on soil productivity could not be blanketed with addition of N, P and K fertilizers because of the effect also of better soil physical conditions. The implication of the palm tree effect on field experimentation in the area was discussed. re]19760712
