This paper discusses changes in the content of zinc and cobalt in plants and soil under the influence of fertilization with phosphorus and potassium. The absorption of Zn and Co with biomass yield and the factors of their bioaccumulation were calculated. Goat’s rue (Galega orientalis Lam.), also known as eastern galega, was cultivated in 2005-2007, on an experimental field owned by the University of Natural Sciences and Humanities in Siedlce. The study included six fertilized objects (control, P50, K100, P50K150, P50K200, P50K250). In each experimental year, three cuts of the test plant at the budding phase were harvested. The total content of zinc and cobalt in the plant and soil was determined with the ICP-AES method on a plasma-induced emission spectrophotometer. The fertilization with phosphorus and potassium significantly contributed to an increase in the Zn content in goat’s rue biomass. The highest concentrations of zinc and cobalt were detected in the test plant fertilized with the K100 dose. Subsequently higher doses of K with P decreaseD the content of the two elements in goat’s rue biomass. The highest absorption of zinc and cobalt by goat’s rue during the vegetation season was recorded for the doses of P50K200 and P50K150, respectively. The highest concentrations of zinc and cobalt were detected in the soil fertilized with P50K250 and P50K150, respectively. The Zn and Co bioaccumulation factors were on an optimal level.
