3- Weeds have increased: Due to heavy crop rotation pattern we do not give rest to land nor we have time to employ proper weed removal system which has increased weeds.
4- Pest infestation has gone up: Pests which we used to control by bio degradable methods have become resistant to many pesticides and now these chemical pesticides have become non effective.
