mowed site, which was within 30 feet of a permanent marker.
These markers made it possible to correlate soil and plant data
from the same areas. Green weights of the samples were re-
corded, and 2- to 3-pound green subsamples were weighed and
dried at 1350F. Oven-dry weights were recorded, and estimates
of dry matter production per acre were calculated. Dry samples
from early-, mid-, and late-season harvests were ground in a
Wiley mill and saved for chemical analysis during 1966, 1968,
1970, and 1972. Rainfall and minimum temperatures are shown
in Table 2. The 1966-67 and 1970-71 seasons were unusually dry,
which resulted in reduced production of both clover and grass.
Minimum temperatures ranged from 15 to 260F and numbers of
days below 320F from 9 to 33 for the 7-year period.

 Results

 Estimated annual yields per acre of oven-dry forage are re-
 corded for each program in Table 3. Program 1 pastures consis-
 tently yielded more forage than those in either Program 2 or 3,
 and Program 2 pastures were more productive than those in
 Program 3 in five of the seven years. Renovation of the Program
 2 pastures early in the period gave partial control of smutgrass,
 but bahiagrass sod did not completely cover all pastures for sev-
 eral seasons, resulting in some yield reduction. Good stands of
 clover were re-established quickly in all renovated pastures. Rye-
 grass and oats furnished 2,000 to 4,000 pounds per acre dry
 weight of forage during February and March of the first year
 of renovation for each pasture. However, overall yields for the
 7-year period were not improved by this procedure or by irriga-
 tion of part of the Program 3 pastures.
