CONCLUSIONS 
The study has shown that the photo-interpretation technique 
normally adopted for small scale soil mapping can be profitably 
employed for large scale soil mapping with suitable adjustments in 
the details of the procedure as required under varying conditions „ 
Soil boundary delineations can be achieved with a higher 
degree of confidence, consistency and accuracy by adopting this 
technique. 
Economy in time and cost is also considerable.
