Question

In what way is the use of a seed drill advantageous over
then why do we need to replenish it?
a field?​

Answer 1

Answer:

Seed drill is more efficient than sowing of seeds by broadcasting because when we seed drill, we place them at regular intervals to each other thus maintaining a constant order in the ploughing field. In broadcasting we cannot maintain proper distance.

Answer 2

Explanation:

Seeds are sown in the field after ploughing. A farmer needs to separate damaged seeds from good seeds. The seeds should be sown at proper gaps and at proper depth. Proper gap between seeds and proper depth in soil ensures adequate sunlight, moisture, air and nutrients to the growing plants.
