Question 1: What effect does soil compaction have on soil permeability and root growth?

Which action should you take?

Choose only one option

It increases microbial activity

It has no effect on root growth

It reduces permeability and restricts root growth

It enhances permeability and promotes root growth

Question 2: What is the impact of introducing rotational grazing in pastureland systems?

Which action should you take?

Choose only one option

It causes soil compaction and increases surface runoff

It depletes soil nutrients and reduces soil organic matter

It helps in maintaining soil health and reduces erosion

It increases pest populations and disrupts soil microbial life

Question 3: Strip cropping is an effective erosion control technique primarily used to:

Which action should you take?

Choose only one option

Promote the growth of high-water-demand crops

Reduce the need for fertilizers and pesticides

Control soil erosion by alternating crops with different root depths and ground cover

Increase crop yield by creating a diverse planting system

Question 4: Which of the following is a sign of poor soil health related to soil structure?

Which action should you take?

Choose only one option

High microbial diversity

Good water infiltration

Well-developed soil aggregates

Presence of hardpan layers

Question 5: What role do windbreaks play in soil erosion prevention?

Which action should you take?

Choose only one option

Increases field evaporation

Increases wind turbulence

Reduces wind speed and protects topsoil

Decreases soil compaction
