Abstract
The characteristics and variability of soils within a 30 ha experiment al site in N.E. Nigeria are analysed in relation to tree establishment . Profile description and analyses for some 480 surface samples of the sandy to clayey surface soils from Lake Chad lacustrine sediments pro vide baseline properties against which anp subsequent modifications re sulting from agroforestry practices can be assessed and to which initi al tree performance can be related. This has been undertaken using pri ncipal component;nd spatial analyses. Inherited soil properties show s patial variations across the site which can be related to the soil tex tural parameters. The initial survival of trees planted for agroforest ry experimentation shows strong correlations with the inherited charac teristics of the soil rather than with acquired soil properties.
