e.g.  Unlike manual harvesting, mechanised harvesters leave stubble and rice paddy straw in the field. Disposing of crop waste is time-consuming. After harvesting rice, farmers get only a short window to plant winter crops such as wheat and rapeseed, and late sowing means lower yields.
So farmers find it much cheaper to burn the residue, which accounts for about a quarter of air pollution.
