Why is acid rain harmful to crops?

How does acid rain affect agriculture?

Vegetation and soil are the prime receptor of acid deposition and function as sink. … Acid rain generally retards the growth of plants by stimulating abnormalities in metabolism of the plants, like photosynthesis, nitrogen and sulphur metabolism, however, there are exceptional cases of promoting growth as well.

How does acid rain affect soil and crops?

Acid rain can damage plants, the soil, and lakes and streams into which it enters (either directly or via the soil). … This can cause acid-sensitive plants to die and can affect the wildlife which feeds on these plants. Thus the overall variety of plants able to grow in a specific area will alter.

How does acid rain destroy plants?
