Answer:
1. First the fields have to be ploughed with the help of a plough . Ploughing is the process of loosening the soil and bringing more fertile soil to the top. Then the process of levelling takes place with the help of a leveller which crushes big pieces of soil called crumbs . Then the seeds are sown.
2. Manure adds nutrients to the soil without affecting its fertility. It does not damage the crops and produces healthy plants. Fertilizers are chemicals which lower the fertility of the soil if used regularly. They also damage the crops and make them unhealthy for consumption.
3. Weed control is important in agriculture. Methods include hand cultivation with hoes, powered cultivation with cultivators, smothering with mulch, lethal wilting with high heat, burning, and chemical control with herbicides (weed killers).
