Summary

In this work the relationship between CO2 emissions and the soil properties of a tropical Brazilian bare soil was investigated.Carbon dioxide emissions were measured on three di€erent days at di€erent soil temperature and the soil moisture conditions,and the soil properties were investigated at the same points that emissions were measured. The soil CO2 emissions were correlated to carbon content, cation exchange capacity and free iron content at the 65 points studied in an area of 100x100 m located in southern Brazil.
