Lighter or finer operations performed on the soil after primary tillage is known as secondary tillage.
After ploughing, the fields are left with large clods with some weeds and partially uprooted stubbles.
Harrowing is to be done to a shallow depth to crush the clods and to uproot the remaining weeds and stubbles.
Disc harrows, cultivators, etc., are commonly used for this purpose.
