The article considers the study results on getting ecologically clean potato yield in the technogenic-contaminated soils through the application of the processed dacite tuff (PDT).
The experiments were carried out in the technogenic-contaminated soils at the Noyemberyan province, where the amounts of mobile heavy metals were considerably high.
The obtained results have disclosed that in case of using PDT (variants-N120P90K90-150 (PDT)) in the fertilization system the content of heavy metals in the tubers was in the permissible limit. While in the control and N120P90K90 (KCl) variants their amounts were much higher than the identified allowable threshold limits.
