Sample practice questions
Easy
1. What does soil analysis determine?
Current soil nutrient levels, pH, and organic matter content
Only the colour of the soil
The crop's growth curve
The market price of the crop
Answer: Current soil nutrient levels, pH, and organic matter content — Soil analysis determines current soil nutrient levels (such as nitrogen, phosphorus and potassium), pH, and organic matter content.
Easy
2. What does plant (tissue) analysis reveal that soil analysis alone might not?
What the plant has actually taken up and is using, which can differ from what soil tests suggest should be available
The exact market price the crop will sell for
The crop's classification as monocotyledonous or dicotyledonous
The total rainfall the field received that season
Answer: What the plant has actually taken up and is using, which can differ from what soil tests suggest should be available — Plant analysis directly tests plant tissue for nutrient content, revealing what the plant has actually taken up and is using, which can differ from soil test results alone.
Medium
3. Name the practice of building a soil sample from multiple sub-samples taken at consistent depth from different points across a field.
Answer: representative sampling — A proper soil sample combines multiple sub-samples taken at consistent depth from different points across a field, giving a representative picture rather than relying on one spot.
