A survey was conducted in the southern mountain coast of Crimea in Ukraine in 2004-2005 to determine Cation Exchange Capacity (CEC) and micro- and macro-element contents in red-brown and brown (natural and park) soils. Results showed that, the exchange capacity of Ca2+, Na+, and K+ in the natural soils was greater than park soils, only EC of Mg2+ was greater in the park soils. In general, natural soils had higher CEC than park soils. It was also established that N, K, Cu, Zn, and Mn contents were higher in the natural soils than in park soils, but P, Pb, Cd, and Co contents were lower. Soil solution reaction (pH) in all soils was neutral. Key words: micro- and macro-elements, shale, bamboo, cedar, oak, cation exchange capacity.
