Most Brazilian soils have severe water limitations for crop growth and, therefore, can benefit from organic amendments. This study evaluated the use of coconut fiber biochar (CFB) as a material for geotechnical improvement of sandy soil. For this, samples of red-yellow latosol with 10% commercial BFC were used. The samples were subjected to pH, electrical conductivity (EC), granulometry, plasticity limit (PL) and liquidity limit (LL) tests. In the pH and EC analyzes it was observed that the soil has an acidic characteristic (pH = 4.8), average ΔpH of -0.6 and EC of 41.7 µS cm-1. When adding CFB, there was an increase in pH values (mean of 6.3 and ΔpH -1.3), EC (80.7 µS cm-1), PL (3.1 to 3.3% nat soil and 3.4 to 4.1% bio soil) LL (13.9 to 17.2% natural soil and 17.2 to 19.6% bio soil). The increase in the values of LL and PL implies in the improvement of water absorption by the soil, minimizing its degradation. It is concluded that BFC is an alternative material that can be used for soil improvement, however, physical-chemical changes should be further investigated.
