1. Which phosphorus index component most directly reflects the risk of dissolved
phosphorus loss from agricultural fields?
A. Soil texture
B. Soil test phosphorus levels
C. Crop rotation
D. Tillage depth
B. Soil test phosphorus levels
High soil test phosphorus increases the likelihood of dissolved P loss in runoff.
2. What is the primary purpose of a nutrient management plan (NMP)?
A. Increase crop yield only
B. Reduce fertilizer costs
C. Protect water quality while optimizing nutrient use
D. Eliminate manure use
C. Protect water quality while optimizing nutrient use
NMPs balance agronomic needs with environmental protection.
3. Which nitrogen form is most susceptible to leaching?
A. Ammonium
B. Organic nitrogen
C. Nitrate
D. Urea
C. Nitrate
Nitrate is highly mobile in soil water and easily leaches.
4. Which factor most influences ammonia volatilization from surface-applied manure?
A. Soil color
B. Wind direction
C. Temperature and pH
D. Crop height
C. Temperature and pH
Higher temperatures and alkaline conditions increase volatilization losses.
5. What is the primary environmental concern associated with excess nitrogen in water
bodies?
A. Soil erosion
B. Eutrophication
C. Soil compaction
D. Salinity
B. Eutrophication
Excess nitrogen stimulates algal blooms that degrade water quality.
,6. Which practice reduces phosphorus runoff risk most effectively?
A. Increasing irrigation
B. Applying manure before rain
C. Incorporating manure into soil
D. Using more fertilizer
C. Incorporating manure into soil
Incorporation reduces surface runoff losses.
7. What is the main purpose of setback distances in nutrient management?
A. Improve crop yield
B. Prevent nutrient movement into water bodies
C. Increase soil fertility
D. Enhance soil aeration
B. Prevent nutrient movement into water bodies
Setbacks protect streams and wells from contamination.
8. Which soil test level indicates excessive phosphorus accumulation?
A. Low
B. Optimum
C. Below optimum
D. Above optimum
D. Above optimum
Above optimum levels indicate risk of environmental loss.
9. What is the key benefit of cover crops in nutrient management?
A. Increase pesticide use
B. Reduce nutrient losses
C. Increase soil erosion
D. Delay planting
B. Reduce nutrient losses
Cover crops capture residual nutrients and prevent leaching.
10. Which factor affects nitrogen mineralization rates?
A. Soil temperature
B. Crop variety
C. Irrigation type
D. Soil color
A. Soil temperature
Warmer temperatures increase microbial activity and mineralization.
11. Which manure storage method reduces nutrient loss?
A. Open pile
B. Covered storage
C. Field spreading
D. Surface dumping
B. Covered storage
Covers reduce volatilization and runoff.
12. What is the primary goal of the phosphorus index?
A. Measure crop yield
B. Estimate phosphorus loss risk
C. Determine soil pH
, D. Calculate nitrogen needs
B. Estimate phosphorus loss risk
It assesses site vulnerability to phosphorus transport.
13. Which nutrient is most associated with groundwater contamination?
A. Potassium
B. Phosphorus
C. Nitrogen
D. Calcium
C. Nitrogen
Nitrate nitrogen is highly leachable to groundwater.
14. What is the effect of over-application of manure?
A. Increased efficiency
B. Reduced runoff
C. Nutrient accumulation and pollution risk
D. Soil sterilization
C. Nutrient accumulation and pollution risk
Excess nutrients lead to environmental degradation.
15. Which method improves nitrogen use efficiency?
A. Broadcasting
B. Split applications
C. Over-irrigation
D. Late application
B. Split applications
Applying nitrogen in stages matches crop uptake.
16. What is the primary concern with winter manure application?
A. Increased crop growth
B. Frozen soil runoff
C. Soil compaction
D. Reduced nutrients
B. Frozen soil runoff
Nutrients cannot infiltrate and are lost in runoff.
17. Which nutrient is least mobile in soil?
A. Nitrogen
B. Phosphorus
C. Sulfur
D. Boron
B. Phosphorus
Phosphorus binds strongly to soil particles.
18. What does calibration of manure spreaders ensure?
A. Faster spreading
B. Accurate nutrient application rates
C. Lower costs
D. Increased yield
B. Accurate nutrient application rates
Calibration ensures proper nutrient delivery.
