Soil Conservation and Farming Practices

What is the primary consequence of soil erosion on agricultural productivity?

• Increased water retention in soil

• Loss of essential nutrients for plant growth

• Enhanced soil fertility

• Reduced need for irrigation

How does runoff water contribute to the loss of topsoil?

• It absorbs nutrients from the soil

• It carries topsoil away during heavy rain

• It compacts the soil surface

• It adds organic matter to the soil

Why is soil recovery critical for maintaining fertile land?

• It prevents water from reaching plants

• It replaces lost topsoil with nutrient-rich soil

• It increases soil erosion

• It reduces the need for composting

Which of the following best describes the purpose of conserving topsoil?

• To increase runoff water

• To prevent loss of nutrients needed for plant growth

• To make soil harder for planting

• To reduce the need for mulching

What is a key challenge when topsoil is deposited in areas like rivers or forests?

• It becomes too wet for use

• It cannot be reused for farming

• It attracts more pests

• It becomes more fertile

Which practice is least effective in preventing soil erosion?

• Mulching with dry grass

• Adding plastic to compost pits

• Planting cover crops

• Shading crops

How does the addition of organic manure improve soil quality?

• It reduces soil water content

• It adds essential nutrients for plant growth

• It compacts the soil surface

• It increases soil erosion

Why is cutting organic materials into smaller pieces important for composting?

• It slows down decomposition

• It makes the compost pit look tidy

• It speeds up decomposition

• It reduces the need for water

Which precaution is critical when handling organic waste for composting?

• Using bare hands to mix waste

• Wearing gloves to maintain hygiene

• Adding chemical containers to the pit

• Leaving the pit uncovered

Why is it problematic to include plastics in compost pits?

• They attract pests

• They do not decompose and contaminate the compost

• They add nutrients to the soil

• They make the compost heavier
