Question 1: What is the impact of reduced tillage practices on soil organic carbon sequestration?

Which action should you take?

Choose only one option

It decreases soil organic carbon levels

It promotes microbial decomposition, reducing carbon storage

It increases organic carbon sequestration by preserving soil structure

It promotes soil erosion and nutrient loss

Question 2: Which of the following factors most significantly influences the effectiveness of contour farming in reducing soil erosion?

Which action should you take?

Choose only one option

The type of irrigation system used

The length and angle of the slope

The type of crops grown

The depth of soil compaction

Question 3: How does the use of cover crops contribute to sustainable agriculture in soil health management?

Which action should you take?

Choose only one option

By providing nitrogen fixation and reducing soil erosion

By reducing biodiversity and depleting soil nutrients

By promoting soil compaction and increasing erosion

By reducing water runoff but increasing soil salinity

Question 4: What is the correct depth for collecting soil samples for nutrient analysis in row crops?

Which action should you take?

Choose only one option

6-8 inches

10-12 inches

2-4 inches

14-16 inches

Question 5: Which practice is most effective in preventing erosion on land that is subject to frost heaving in winter?

Which action should you take?

Choose only one option

Increasing tillage depth to promote soil structure

Installing drainage systems to remove excess water from the soil

Applying organic matter to bind the soil particles

Implementing mulching to protect the soil surface from freeze-thaw cycles

Question 6: How does soil texture affect the application rate of nitrogen fertilizers?

Which action should you take?

Choose only one option

Clay soils have no leaching issues

Sandy soils require split applications

Sandy soils reduce volatilization risk

Clay soils require less frequent applications
