Cadmium Accumulation and Immobilization by Artemisia selengensis under Different Compound Amendments in Cadmium-Contaminated Soil

Cadmium (Cd) contamination is a global environmental challenge that threatens human food security. Lime combined with five different organic materials (rape seed cake, mushroom residue, straw, sawdust, and corn cobs) (LOM) at application ratios of 1:1 lime sawdust nitro-compound fertilizer (Ca(NO3)2·4H2O, KH2PO4, KNO3) (LSF) rates were applied to Cd-contaminated soil. The present study investigates the effects these organic–inorganic compound amendments on Cd bioavailability in soil, uptake accumulation by edible Artemisia selengensis parts. A. was cultivated for three consecutive seasons LOM LSF treatments obviously reduced Cd. Compared control contents parts decreased 19.26–33.33% 26.67–32.78% first season, 18.60–32.79% 18.37–32.79% second 20.45–40.68% 34.32–37.27% third respectively. addition + Mushroom Residue 70% Nitro-compound Fertilizer Sawdust most significantly concentrations season. increased soil pH improved fertility, including available nitrogen, phosphorus, potassium, matter, cation exchange capacity. plant yield most. In addition, had lowest health risk indices, conclusion, risks, enhanced growth, promoted sustainable development arable land under remediation.
