B – Arrow	Metal pin used to mark positions for measurements
C – Measuring tape	Flexible ruler to measure distance or size
D – Wooden peg	Marks permanent boundaries of surveyed land

1d. Care of Farming Tools

• Clean poles regularly to remove dirt and mud.

• Remove rust and dirt from arrows.

• Wipe tapes after use to remove debris.

• Ensure wooden pegs are dry and crack-free.

2. Soil Experiments and Capillary Rise

2a. Aim: Determine the capillary rise of water in dry sand, clay, and loam.

2b. Observations:

• E: Least rise

• F: Moderate rise

• G: Highest rise

2c. Key Points (Pick any two):

• Soil type influences rise.

• Loam has the highest rise due to texture.

• Clay exhibits moderate capillary action.

• Sand shows the least rise.

• Particle size affects capillary action.

• Water retention varies with soil composition.

2d. Purpose of Filter Paper/Separator (Pick one):

• Prevents soil particles from escaping

• Ensures even water absorption

• Maintains consistency in the experiment

2ei. Best Soil for Agriculture: Soil in capillary tube E

2eii. Advantages of Soil E (Pick any two):

• Good drainage to prevent waterlogging

• High permeability for nutrient uptake

• Easy cultivation with good soil structure

• Suitable for crops requiring well-drained conditions

• Less prone to compaction

2f. Draw diagram of capillary rise experiment (students draw in exam)
