Answer 2

Stubble burning, as it is commonly known, has its ups and downs.

 

Pros

·         It kills herbicide resistant weeds

·         Kills pests, slugs etc.

·         It is cheap and quick

 

Cons

·         The intense heat destroys nutrients in the soil

·         Causes pollution from the thick smoke

·         Fire risk – risk of fire spreading and getting out of control

 

Alternate methods of stubs disposal should be considered, as drawbacks far outweigh the merits of stubble burning.
