Puccinellia were planted at one of these freshly oiled sites (Fig. 42).
Cover and survival data determined 1 year later indicate no noticeable
effect of the oil on either species (Table 12, Fig. 43) as compared to
these data from transplants at unoiled sites which were planted the
same year (Table 9). As in many other experiments, cover data
indicated a significant transplant response to fertilizer materials
with best growth realized in the Osmocote slow release treatment.
