It was established that the contents of nitrogen, potassium, phosphorus, sodium, calcium, manganese, and ashes in cranberry (Oxycoccus palustris Pers.) fruit growing in different habitats varied among habitats and years. The highest variation was observed in the contents of sodium. In the reed-bed habitat, the cranberries accumulated three times more sodium than on the lakeside bog. The contents of nitrogen varied less. The highest content of nitrogen was observed in berries growing on the forest edge, and the lowest content – on the lakeside bog habitat. The differences in nitrogen contents among habitats did not exceed 30 %. The contents of calcium varied slightly, differences between habitats did not exceeding 25 %. The contents of phosphorus and potassium were also similar in all habitats. The lowest content of manganese was observed in berries picked up on the lakeside bog. In other habitats its contents were higher by 1.7–2 times. The lowest content of ashes was observed in cranberries on the raised bog, while in other habitats it was higher by 20 %.
