The cation exchange capacity (C.E.C.) of the roots of 20 plant species was measured by a rapid technique not involving toxic reagents or harmful temperatures. Significant differences between the root C.E.C. of various species were found, and with three exceptions, legumes > herbs > grasses. Nitrogen supply had little effect on the legumes and herbs, but significantly increased the C.E.C. of two grasses. The concentrations of calcium and phosphorus in the tops of plants utilizing rock phosphate were each positively correlated with root C.E.C. The concentration of phosphorus was not greater in the tops of plants with relatively large root systems.

Since year 1977 until 2005, PT. ANTAM has been exploited nickel ore resources at Gebe Island – Center ofHalmahera District – North Maluku Province. Mining activity, beside give economically advantages also causedegradation of environment quality espicially land quality. Therefore, it need evaluation activity for change ofland quality at Gebe Island after mining activity.From chemical rehabilitation aspect, post mining land and rehabilitation land indacate very lack and lackfertility (base saturated 45,87 – 99,6%; cation exchange capacity 9,43 – 12,43%; Organic Carbon 1,12 –2,31%). From availability of nutrirnt element aspect, post mining land and rehabilitation land indicate verylack and lack fertility (nitrogen 0,1 – 1,19%). Base on that data, it can be concluded that land reclamationactivity not yet achieve standart condition of chemical land.Key words : land quality, post mining lan
