Mastering ecological dynamics necessitates identifying the substance cycles in biomass. In terms of sustainable soil productivity, the nutrient content of below-ground biomass is just as significant as the above-ground biomass, which fluctuates depending on land use. Yet, there were limited studies on determining the quantity of plant nutrient stocks, particularly in the below-ground biomass, in rangeland, forest, and plantation areas coexisting in the same ecological zone. In this regard, it is expected that the findings of this study will contribute to the literature. For this purpose in mind, distinct samples were taken from three depth levels (0-10 cm, 10-20 cm, 20-30 cm) to determine root biomass and nutrient stocks of roots in neighboring rangeland, forest, and plantation areas, and roots were divided into diameter classes, and below-ground biomass amounts and nutritional contents of below-ground biomass were determined. According to the results obtained, the total root biomass in the rangelands is 8.02 Mg ha(-1), total root biomass was 5.95 Mg ha(-1) in forest areas, and in plantation areas, the total root biomass is 6.94 Mg ha(-1). Root biomass in the 0-10 cm soil layer constituted 78% of the total biomass. Also, for all land uses, the highest below-ground biomass concentrations were observed for Al, Fe, K, Mg, and Ca. The amounts of Al, Fe, K and Mg in the below-ground biomass followed the sequence of rangeland, plantation, and forest from high to low. Nutrient stocks in below-ground biomass and the effects of increases in root biomass on plant growth should be evaluated by future studies.
