Question 1: What is the most significant benefit of using vermicomposting in agricultural systems?

Which action should you take?

Choose only one option

It reduces soil compaction and increases water runoff

It reduces biodiversity and crop diversity

It provides high-nutrient organic matter and improves soil structure

It causes soil salinization and acidification

Question 2: Which soil health indicator is most reliable for evaluating soil structure in relation to crop production?

Which action should you take?

Choose only one option

Cation exchange capacity (CEC)

Aggregate stability

Soil pH

Soil respiration rate

Question 3: What is the purpose of using controlled-release fertilizers in fertigation systems?

Which action should you take?

Choose only one option

To enhance microbial activity in the soil

To prevent the over-application of nitrogen and phosphorus

To reduce the risk of salt damage to crops

To match nutrient release with crop nutrient demand

Question 4: Which is the most effective method for managing surface runoff that contributes to erosion in agricultural fields?

Which action should you take?

Choose only one option

Planting monoculture crops to reduce water uptake

Installing buffer strips along watercourses to trap sediment

Removing all plant cover to increase water absorption

Increasing the tillage depth to improve water infiltration

Which action should you take?

Choose only one option

Organic matter content

Electrical conductivity

Soil texture and pH

Soil temperature and moisture content

Question 6: How does agroforestry contribute to sustainable soil use?

Which action should you take?

Choose only one option

Enhances biodiversity and reduces erosion
