Abstract

Salt stress, with nutrient deficiency, has been threatening plant growth in coastal saline soil. This study is to address the potential of using biochar treated with 1.69 mol/L HNO3 (BCH) as a soil amendment to ameliorate coastal saline soil. Both BCH and BCH with fertilizer treatments increased plant height and biomass of sesbania (Sesbania cannabina) and seashore mallow (Kosteletzkya virginica), especially at the adding rate of 1.5% (w/w). The maximal biomass of sesbania and mallow was increased by 158%, and 214%, respectively. However, with the increasing adding rate, the value of biomass and height for both plant decreased, but not lower than those of the control. It suggested that the biochar treated by HNO3 is a good way to overcome biochar’s inherent nutrient deficiency and ameliorate the soils with salt stress.
