The impact of foliar fertilization with zinc (ZnSO₄) and manganese (MnSO₄ on ¹³⁷Cs uptake by spring wheat and potato was studied. The experiments were conducted during 3 years (2014–2016) in a¹³⁷Cs-contaminated area, Zhytomyr region of Ukraine. The fertilization was carried out on podzolic loamy sand soil, poor in most of the microelements. Both crops were fertilized at four successive stages of growth. Foliar application of fertilizers caused higher yield of wheat grain/straw and potato tubers yield in 2014–2015 years but had no effect in 2016. Thus, the overall effect of fertilization between 2014 and 2016 was less pronounced and generally insignificant. Application of Zn, Mn and EDTA reduced ¹³⁷Cs uptake by wheat grain and potato tubers, when fertilized at earlier stages of growth and development in years 2014 and 2015 by factor 1.5–2.0, while in 2016 the effect was generally statistically insignificant. It is suggested, that reduction of ¹³⁷Cs uptake by spring wheat and potato, at least partly, was caused by an effect of radionuclide dilution due to the higher biomass of the plants. A foliar spray of EDTA at earlier stages of plant growth and development may be considered as a potential countermeasure aiming reducing ¹³⁷Cs uptake from soil to plants, even if such effect appeared to be conditional.

叶面施肥的与锌（硫酸锌的影响₄）和锰（的MnSO ₄上¹³⁷ Cs的摄取春小麦和马铃薯进行了研究。在实验期间，在3年（2014年至2016年）进行的^137个铯污染区，日托米尔地区在乌克兰的Podolic壤质砂质土壤上施肥，大部分微量元素都贫瘠，两种作物都在连续四个生长阶段施肥，叶面施用肥料导致小麦籽粒/稻草和马铃薯块茎的单产提高，2014年–2015年，但在2016年没有影响。因此，2014年至2016年间施肥的整体效果较不明显，总体上不显着，锌，锰和EDTA的施用减少了¹³⁷小麦籽粒和马铃薯块茎在2014年和2015年受生长和发育的早期阶段施肥时，其Cs吸收系数为1.5-2.0，而2016年的影响总体上无统计学意义。有人认为，春季小麦和马铃薯吸收¹³⁷ Cs的减少至少部分是由于植物较高的生物量引起的放射性核素稀释作用所致。在植物生长和发育的较早阶段喷洒EDTA叶可能被认为是旨在减少从土壤到植物的¹³⁷ Cs吸收的潜在对策，即使这种效果似乎是有条件的。
