In addition, physical chemical conditions are also measured. results showed that rate colonization at moderate high an average 22.8%. this averaged 10/50 g sample soil. number belongs category, however characteristics location show uniqueness its own makes population not too much. Spore were found 4 each Glomus Acaulospora. conclusion obtained there a symbiosis between plants mining
