Synergic effects of biochar and polyacrylamide amendments

A PAM amendment in coastal silt loam soil increased the FS significantly ( P < 0.05) and minimized the negative effects on the FS that was caused by the biochar amendment. Therefore, biochar and PAM could be applied to silt loam soil together to improve soil quality to enhance the slope stability under coastal reclamation in China.
