With the aim of studying soil macroelement in each of Populus deltoiedes, Alnus subcordata, Taxodiom distichum stands and around uncultivated area (control), 8 samples taken from each of 0-15cm and 15-30cm depth. Soil sample for measuring the amount of soil macroelements such as nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg), calcium (Ca) and some physicochemical characters were transferred to the laboratory. The result showed most amounts of total nitrogen (0.34%) and available Calcium (6379.37 ppm) observed in the Taxodiom stand, the highest amount of available phosphorus (18.59 ppm) and magnesium (638.75 ppm) fond in Alnus stand, and the maximum amount of availble potassium observed in the Populus stand. The most of soil macro element except available calcium (293.62 ppm), observed in 0-15cm depth of all study stands and control area. This study suggests that plantation in uncultivated and disturbed area can be positive step towards increasing the soil richness and fertility; witch in Ecosystem management should be considered.
