Preview Questions Soil Scientist | Role Specific Skill

Question 1: In regions with heavy rainfall, which soil management technique is most effective in preventing sheet erosion?

Which action should you take?

Choose only one option

Applying chemical inhibitors to stabilize soil particles

Increasing the frequency of irrigation to prevent soil crusting

Using contour plowing to follow the natural slope of the land

Broad-acre tilling to aerate the soil and promote root penetration

Question 2: What is the main difference between ammonium-based and nitrate-based nitrogen fertilizers in terms of their impact on soil pH?

Which action should you take?

Choose only one option

Ammonium-based fertilizers lower soil pH, while nitrate-based fertilizers increase soil pH

Nitrate-based fertilizers lower soil pH, while ammonium-based fertilizers have no effect on pH

Both ammonium and nitrate fertilizers have the same effect on pH

Neither affects the soil pH significantly

Question 3: In dryland farming systems, which practice is most effective in preventing wind erosion?

Which action should you take?

Choose only one option

Maintaining continuous ground cover using drought-tolerant plants

Removing stubble to reduce wind resistance

Increasing irrigation to prevent soil from drying out

Plowing the soil to loosen it for better air circulation

Question 4: In evaluating soil health, which indicator is most important for assessing soil biological activity?

Which action should you take?

Choose only one option

Soil respiration rate

Soil texture

Soil nutrient content

Soil water retention

Question 5: Silvopasture is a sustainable farming practice that combines:

Which action should you take?

Choose only one option

Monoculture crops and livestock to increase land productivity

Forests with livestock grazing to enhance biodiversity and improve soil health

Annual crops with livestock grazing for maximum production

Aquaculture with forestry to optimize land use

Question 6: Which parameter is best suited to assess the soil's capacity to retain nutrients for plant use?

Which action should you take?

Choose only one option
