Agricultural crop influences availability of nickel in the rhizosphere; a study on base cation saturations, Ni dosages and crop succession

Nickel availability in the soil is altered mainly by pH, which can indirectly be changed by base saturation (BS). The objective was to evaluate the effect of consecutive plants growth on Ni availability and enzymatic activities in the rhizosphere. It was evaluated the interaction between BS ratios (50% and 70%) and Ni application rates (0, 0.1, 0.5, 1.0, and 10.0 mg dm−3 of soil) on the availability of Ni in the rhizosphere. Two agricultural...
