Not only might chlorine be a direct factor, it might act by damaging or
destroying good soil organisms that benefit plants.
Here's another possibility. Heavy rains often occur during rainstorms.
Lightening discharges are powerful enough to convert some of the nitrogen
gas in the air into soluble nitrates, which then dissolve in the rain and
fertilize the plants. So that sort of rain, at least, is a dilute
fertilizer solution.
Seriously, it is known that many tons of nitrate are added to soils
world-wide in this way every year.
