Potential of rice straw biochar, sulfur and ryegrass (Lolium perenne L.) in remediating soil contaminated with nickel through irrigation with untreated wastewater.

ABSTRACT:

Background

Untreated wastewater carries substantial amount of heavy metals and causes potential ecological risks to the environment, food quality, soil health and sustainable agriculture.

Methodology

In order to reduce the incidence of nickel (Ni²⁺) contamination in soils, two separate experiments (incubation and greenhouse) were conducted to investigate the potentials of rice straw biochar and elemental sulfur in remediating Ni²⁺ polluted soil due to the irrigation with wastewater. Five incubation periods (1, 7, 14, 28 and 56 days), three biochar doses (0, 10 and 20 g kg^-1 of soil) and two doses of sulfur (0 and 5 g kg^-1 of soil) were used in the incubation experiment then the Ni²⁺ was extracted from the soil and analyz
