Question

why even excess application of manure does not cause pollution???plzz answer fast

Answer 1

Manure is mostly made up of organic matter like leaves, cow dung, animal excreta, vegetable peels etc which are biodegradable and does not contain any harmful chemicals.

Thus, they do not cause any environmental pollution.
