Plants need nutrients from the soil. Soil nutrients are called fertilizer. Are you suggesting plants can get all their nutrients from pollination???
That doesn’t sound ignorant at all.
Here’s some observations about the site of a meteor blast.
Following the 1908 Tunguska meteoritic blast.
"After 1958, expeditions to the Tunguska region also noted genetic changes in the plants at the fall point
since 1908. There was accelerated growth both in new trees and in those damaged by the explosion. In
some cases, a fungus infection had spread over the dead wood, then been covered by the wild new
growth. Examination of growth rings on living trees showed that around the period of the blast there
was a noticeable increase in cell production; the rings were both wider and more pronounced. Those
before 1908 varied from .04 to 2 millimeters in width, while after the blast they became as wide as 5 to
10 millimeters. Trees which germinated after the explosion would normally have grown to about 23 to
26 feet in height by 1958; instead, they towered between 55 and 72 feet high. Some of those which
survived the blast were now almost four times their expected girth.
Zolotov's 1959 expedition drew attention to these anomalies, and Florensky's 1961 party made detailed
examinations. The latter's report stated that "the features of accelerated tree growth established in
1958 have been confirmed by a great volume of data and are peculiar to the central region of the impact
area. In view of the fact that the causes of the phenomena are not clear, work along this line should be continued." Later the report said, "Although
literature sources indicate that the aftereffects of ordinary forest fires and forest uprooting with which we are familiar from European silviculture
should not last longer than 15 to 20 years, they persist, occasionally without noticeable abatement, for a period of 40 to 50 years in the area of the
meteorite fall. V. I. Nekrasov [participant in 1961 expedition] has expressed doubt as to the possibility of explaining this phenomenon in terms of
purely ecological factors." Thinking
that meteoric dust may have fertilized the area so as to encourage growth, the 1961 party planted test
areas of grain to see if it grew better than in traditional soil. It did not, proving that whatever affected the trees at the fall point did so only
at the instant of the blast and for a short time thereafter."
