TITLE OF STUDY ; Reclamation Techniques for Heavy Metal 

 Contaminated Pasturelands in Deer Lodge, Powell and Silver 

 Bow Counties 



CONTACTS ; Ted Dodge - Headwaters Resource Conservation and 

 Development Area Coordinator - Butte - 782-7333

OBJECTIVE: Develop reclamation techniques for heavy metal 

 contaminated pasturelands, while ensuring that changes in 

 land use do not negatively impact the surface and ground 

 water resources of the area. 



DURATION ; August 1984 - October 1987 



CURRENT STATUS ; Test plots which will evaluate the success 

 of various combinations of tillage techniques, liming rates 

 and plant (forage) species, have been established at the 

 Hazel Spangler Ranch near Gregson. All plots established in 

 1985 were in dry pasture areas. Soil chemistry measurements, 

 including extractable metal concentrations, were conducted 

 prior to and after the lime applications. The survival and 

 growth rate of various plant species were measured, but 

 severe drought conditions during the spring and summer of 

 1985 had a definite impact upon interpretation of the 

 results.
