Zero-valent iron (ZVI) represent a promising agent for environmental remediation. The research was aimed to determine the influence of copper in doses of 0, 80, 150, 300, and 600 mg Cu·kg⁻¹ of soil as well as ZVI, and lignite additives on the content of macroelements in the Indian mustard (Brassica juncea (L.) Czern.). The average accumulation of analyzing elements in Indian mustard grown in copper contaminated soil were found to follow the decreasing order Mg > Na > P > Ca > K > N. Soil contamination at 600 mg Cu·kg⁻¹ of soil led to the highest increase in P, Mg, N, and Ca content. The application of ZVI had a positive influence on the average phosphorus and potassium content of Indian mustard. Moreover, the application of ZVI and lignite had a positive influence on the average Mg and Ca content in the above-ground parts of Indian mustard. From the analyzed reactive materials, the application of lignite was shown to be the most effective resulting in the decrease in the average nitrogen and calcium content when compared to the control crop. Calcium content in plants from the control group, without the addition of zero-valent iron, and powered lignite (control), was positively correlated with increasing doses of copper.
