Abstract: The typical basalt-derived latosol was selected from Hainan area to study the influence of biochar and straw on soil p H,exchangeable acid and exchange performance. The trial consisted of 4 treatments: control( CK),biochar( B),biochar and corn straw mixture( BCS),corn straw( CS). The trial results shawed addition of biomass materials,jmproved the soil p H,to some extents,reduled obviously the soil exchangeable acid,and improved signifilantly the soil cation capacity( CEL) exchangeable base and base saturation with the treatment effect in the order of CS > BCS > B > CK.
