AB  - This research is about the use of <I>manipueira</I>, a liquid extract obtained from the cassava processing as biofertilizer in crops and its effects on soil as well as on subterranean waters. The physical-chemical characterization of the effluent showed the following results: pH (23?C): 3.6, cyanide: <0.05 mg L<SUP>-1</SUP>, COD: 7,747.00 mg L<SUP>-1</SUP>, BOD<SUB>5 days</SUB>: 5,660.00 mg L<SUP>-1</SUP>, total phosphorus: 36.80 mg L<SUP>-1</SUP>, nitrogen: 167.00 mg L<SUP>-1</SUP>, sedimentary solids: 48.00 mg L<SUP>-1</SUP>, total solids: 6,024.00 mg L<SUP>-1</SUP>. Despite the physical-chemical composition of the subterranean waters there was a pH increase from 4.8 (monitored area) to an average of 7.0 (control area). Other parameters analyzed (except sedimentary solids) showed a significant increase in COD, BOD, phosphorus, nitrogen and total solids in the control area, showing that the effluent may contaminate the subterranean waters. However, the increase in the organic substances, potassium and phosphorus in the soil presents a potential of being used as a fertilizer reflecting in final crop production.
