A laboratory approach for investigations into the potential effectiveness of potassium-based fertilisers in reducing radiocesium transfer from soil to plant

The paper presents a laboratory experimental model based on a simplesoil-plant system used to investigate the potential effectiveness of potassium-basedfertilisers in reducing soil-to-plant transfer of radiocesium. The soil-plantsystem, slightly modified comparing to that described originally in the NEUBAUER'splantlet method, consists in wheat plantlets grown from caryopsis phase onbrown acid soil contaminated with ¹³⁷Cs resulted from Chernobylnuclear accident and treated with potassium salt of 30%. The effectivenessof 30% potassium salt applied to the soil as treatment is discussed in termsof reduction factor for ¹³⁷Cs soil-to-plant transfer coefficientand ¹³⁷Cs ⁺ :K ⁺ ratio in soil and plantlets.
