Which action should you take?

Choose only one option

Nitrification test

Kjeldahl method

Nitrate-Nitrogen test

Ammonium acetate extraction

Question 2: What is the significance of soil porosity in assessing soil health?

Which action should you take?

Choose only one option

Increases soil erosion

Determines water and air movement

Improves salinity resistance

Reduces soil organic matter

Question 3: How does terracing help in soil erosion prevention on sloped agricultural lands?

Which action should you take?

Choose only one option

It makes the land more suitable for planting shallow-rooted crops

It reduces the velocity of water runoff by breaking the slope into smaller, manageable segments

It enhances the fertility of soil by improving the nutrient cycling process

It increases the infiltration rate of water, preventing runoff

Question 4: When determining the appropriate fertilizer rate, which factor is most important to consider?

Which action should you take?

Choose only one option

The cost of fertilizer per kilogram

The type of irrigation system used

The method of fertilizer application

The nutrient requirements of the crop and the current nutrient content of the soil

Question 5: Which method is most commonly used to evaluate soil microbial biomass in terms of soil health?

Which action should you take?

Choose only one option

Microbial carbon determination

Soil respiration measurement

PLFA (Phospholipid Fatty Acid) analysis

Enzyme activity measurement

Question 6: How does the practice of mulching contribute to sustainable agriculture?

Which action should you take?

Choose only one option

By compacting the soil and improving its nutrient density

By reducing biodiversity and promoting monoculture

By increasing soil temperature, promoting weed growth

By preventing soil erosion and retaining soil moisture
