Hi all,
Do acid rains have any measurable, negative effect on organic crops, in term of the health of people eating those crops?
Put it another way are organic, certified crops tested also for their content in toxic materials coming from the sky?
Are there any studies available on this subject?
There seems to be little that the farmer can do about that.
Cheers

=========================================

Acid rain is mainly negative in that it acidifies the soil which, if too acid, loses its minerals and micro-nutrients. It also releases some minerals from parent material that may be toxic to plants in high concentrations ie copper, aluminium, etc.
