Question 2: What is the role of an irrigation controller in a modern irrigation system?

Which action should you take?

Choose only one option

It measures soil moisture and adjusts watering schedules

It filters the water before distribution

It monitors water usage for billing purposes

Question 3: How does climate change affect pest dynamics in crop fields?

Which action should you take?

Choose only one option

Alters pest distribution and increases outbreaks

Increases pest resistance to pesticides

Reduces pest migration

Shortens pest life cycles

Question 4: What is the effect of over-irrigation in agricultural fields with sandy soil?

Which action should you take?

Choose only one option

It results in uniform crop growth

It decreases root oxygen availability

It leads to nutrient leaching and reduced crop yield
