Which is the secondary tillage operation?

✅ EXPLANATION: Secondary tillage operations are performed after the primary tillage operations. They are used to further prepare the soil for planting. The two main secondary tillage operations are disc harrowing and blade harrowing.
🔹 Disc harrowing is the process of breaking up clods and levelling the soil. This is done by using a disc harrow, a machine with discs that rotate and cut the soil.
🔹 Blade harrowing is the process of breaking up clods and mixing the soil. This is done by using a blade harrow, a machine with blades that rotate and cut the soil.
