Flood plains along the Amazon river and its tributaries -

The table presented in the next page is a synopsis of.the 
results obtained by the Soil Science~Team in the areas already - 
investigated. 
Besides the above mentioned activities developed by the 
Soil cientists, they are performing the following other relevant 
tasks: 
- "Intensive training courses in Soils Exploratory Survey and Land 
Management by RADAR imagery interpretation. 
- Advice to the road designers to avoid swamps, marshes and lar-
