This study sought to characterize soils from D.R. Congo and devise fertility capability classification interpretations for their agronomic use. Twenty 24 soil pedons were sampled in seven administrative provinces selected to represent the most commonly used landscape positions and to include soils from a variety of soil parent materials occuring throughout the country. Most of the soils studied have both surface and subsoil acidity problems, they have low available phosphorus and total nitrogen contents, and a low capacity to supply potassium. Half of the pedons studied have low contents of...
