Short summary
In this work, the combined SM500 + S2 treatment was the most effective with respect to reducing the Ni water-soluble and exchangeable fraction. Application of Si and biochars decreased the soil Ni diethylenetriaminepentaacetic acid and corn Ni shoot content. The study shows the synergistic potential of Si and sheep manure biochars for immobilizing soil Ni.
