Preview Questions Soil Scientist | Role Specific Skill

Question 1: Which factor primarily influences the formation of gully erosion in agricultural land?

Which action should you take?

Choose only one option

Low organic matter

Low cation exchange capacity

High-intensity rainfall

Excessive soil compaction

Question 2: What is the effect of soil compaction on soil health and crop production?

Which action should you take?

Choose only one option

Improves water retention

Enhances root penetration and nutrient uptake

Increases microbial diversity

Decreases root growth and water infiltration

Question 3: What is the role of vegetative cover in preventing soil erosion during heavy rainfall events?

Which action should you take?

Choose only one option

It acts as a physical barrier that reduces the speed of surface runoff and protects soil from raindrop impact

It promotes the dissolution of salts, preventing soil salinization

It improves the chemical structure of the soil, increasing its ability to retain moisture

It absorbs excessive rainfall, preventing waterlogging

Question 4: What is the role of no-till farming in preventing soil erosion?

Which action should you take?

Choose only one option

It increases water runoff and accelerates soil erosion

It promotes weed growth that can destabilize the soil

It reduces soil disturbance and maintains organic matter

It enhances soil compaction and root penetration

Question 5: What is the key benefit of contour farming in soil sustainability?

Which action should you take?

Choose only one option

It improves soil compaction, making it suitable for heavy machinery

It reduces soil erosion by following the natural contour of the land

It increases water runoff, preventing waterlogging

It promotes the use of chemical fertilizers to enhance soil productivity

Question 6: What is the most commonly used reagent in soil organic carbon testing?

Which action should you take?

Choose only one option

Sodium bicarbonate

Magnesium sulfate

Calcium chloride

Potassium dichromate
