Question

Which type of mould board is used in sticky soils as primary tillage equipment?

• A. General Purpose Mould Board
• B. Slat Mould Board
• C. Stubble Mould Board
• D. Sod Mould Board

Hint:

For sticky soils, use a slat mould board to prevent clogging and improve efficiency.

Answer 1

The Correct Option is B

Step 1: Understanding the function of a mould board
A mould board is a part of a plough that helps in inverting the soil during primary tillage.
Step 2: Selecting the correct mould board for sticky soils
- General Purpose Mould Board: Suitable for a wide range of soils but may clog in sticky conditions. - Slat Mould Board: Has spaced slats to reduce adhesion, making it ideal for sticky soils. - Stubble Mould Board: Used for ploughing fields with plant residues. - Sod Mould Board: Used for cutting through sod and grassy fields.
Step 3: Conclusion
Since sticky soils tend to clog solid mould boards, slat mould boards are preferred as they reduce adhesion and require less draft power.
