Also evaluated was a sprinkler system for placement on active tailing ponds
for the possible prevention of fugitive dust conditions. The system was
designed for use when the surface of the pond is dry enough to move under
the influence of wind. Additional development of the system was dropped in
1972 due to successful experiments with chemical stabilizers and the
impractibility of the sprinklers at the time.
Following the testing of the various chemical agents, Coherex was selected
as the best suppression agent.
Climax is continuing research in the area of fugitive dust suppression.
9.1.4 Manure Application Rate Field Study 1973
Preliminary to this study greenhouse
Barrou 1977) revealed that to obtain
tailing, three steps must be taken:
studies on Climax tailing (Berg &
maximum vegetation cover on the
1. Liming
2. Leaching treatment after liming
3. NPK fertilization
Under field conditions, application of adequate lime and rvaintaining
adequate N levels for optimum plant growth are difficult. In 1573 a manure
application rate study was put in to evaluate the effectiveness of using
moderate to high rates of manure to maintain plant-available N in the
tailing under field conditions at Climax. The study was conducted by Dr.
Berg of CSU and his graduate student, Henry Barrou.
Materials and Methods
The manure study on the tailing contained five treatments (control, 10, 20,
40, and 80 tons/acre of manure) with four replications. The plot area was
14.6 m (48 ft) wide by 54.9 m (180 ft) long, and each individu+sl plot was
3.7 m (12 ft) wide by 11 m (36 ft) long.
