    Land characteristics associated with the growing requirements of plants. Physics research to study the character of land tailings deposition is performed to determine its condition to the growth of vegetation has been done. Mining activities will result in the form of sludge disposal is known as a tailings sand. To produce about 3-4% concentration of metallic minerals (copper, gold and silver), PT Freeport in Papua spends about 96-97% tailings. Tailings are discharged and deposited in a special area who engineered the deposition called ModADA (Modified Ajkwa Deposition Area). Tailings deposition causes changes in the ecosystem and affect the characteristics of the land, as well as affecting the diversity of vegetation growing. Research conducted in separate areas in ModADA where biophysical conditions of the region has envolved as a natural revegetation and reclamation. Methodology used is a method of using Landsat survey to determine the sampling point. Soil sample taken at 0-30 cm depth by drilling to a depth of 120 cm. Location decision based on the density of vegetation. Soil texture, drainage, effective depth, and soil color is a land of physical parameters were observed. The results showed that the biophysical characteristics of tailing deposition area affecting vegetation growth. Factor of water avaibility, rooting conditions and retention of nutriens become the limiting factor for the growth of vegetation on the tailing deposition area.
