on mineral soils has not been fully established. Heavily grazed
or harvested pangolagrass may benefit from additional appli-
cations of copper at 0.1 units to a maximum of 0.25 units per
acre each second year.
 Fertilization should be scheduled to obtain efficient use of
forage, with time and rate of application being based on cattle
needs and weather conditions. A growth period of at least 30
days between fertilization and grazing should be provided unless
the grass is 6 to 12 inches in height at time of treatment. As
much as 60 days of growing time is needed in the fall of the
year to provide forage for midwinter grazing.

Fertilization for Harvest
 Harvest of a heavy crop of grass for either hay, silage, or
planting material removes as much nitrogen and potassium and
half as much phosphorus as is contained in 600 pounds of 10-
10-10 fertilizer (19). These nutrients must be replaced follow-
ing harvest to produce rapid regrowth and high quality forage.
 Higher potassium fertilization rates produce the most pango-
lagrass response during the cool, low-rainfall periods of the
year, whereas nitrogen is important during all growing periods
(20, 22). One or two applications of fertilizer, each supplying 50
