1. The primary purpose of Florida's Green Industries Best Management Practices
(GI-BMP) program is to:
A. Increase fertilizer sales
B. Protect water resources through environmentally responsible landscape
practices
C. Eliminate all pesticide use
D. Regulate construction permits
Answer: B
Rationale: GI-BMP focuses on reducing nutrient and pollutant movement into
Florida waters while maintaining healthy landscapes.
2. Case: A landscape manager is responsible for maintaining a property adjacent
to a lake experiencing algae blooms. Which action best supports BMP goals?
A. Increase nitrogen applications year-round
B. Apply fertilizer immediately before heavy rainfall
C. Use proper nutrient management and maintain setbacks from water bodies
D. Remove all vegetation along the shoreline
Answer: C
Rationale: Nutrient management and protective buffers help reduce nutrient
loading into water bodies.
3. Which soil property most directly influences nutrient-holding capacity?
A. Soil color
,B. Cation exchange capacity (CEC)
C. Surface temperature
D. Slope length only
Answer: B
Rationale: CEC measures the soil's ability to retain positively charged nutrients.
4. Case: A sandy Florida soil shows repeated nutrient deficiencies despite
regular fertilization. The most likely explanation is:
A. Excessive cation exchange capacity
B. Low nutrient retention and leaching potential
C. Excessive clay content
D. Lack of sunlight
Answer: B
Rationale: Sandy soils have limited nutrient-holding capacity and are prone to
leaching.
5. Which nutrient is most commonly associated with excessive algal growth in
freshwater systems?
A. Calcium
B. Sulfur
C. Phosphorus
D. Iron
Answer: C
Rationale: Phosphorus often drives eutrophication in freshwater environments.
6. Case: A soil test indicates phosphorus levels are already high. Under BMP
principles, the applicator should:
A. Continue applying phosphorus at standard rates
B. Increase phosphorus to stimulate roots
C. Avoid unnecessary phosphorus applications
D. Double all fertilizer rates
Answer: C
Rationale: Excess phosphorus contributes to water-quality impairment and should
be avoided when not needed.
7. The most reliable method for determining nutrient needs is:
A. Neighbor recommendations
, B. Visual inspection only
C. Soil testing and site assessment
D. Fertilizer manufacturer advertising
Answer: C
Rationale: Soil testing provides objective information for nutrient management
decisions.
8. Case: A property owner requests fertilizer applications every month despite
healthy turf and acceptable soil test results. The BMP-certified professional
should:
A. Follow the request without question
B. Recommend applications based on actual need
C. Apply extra fertilizer to ensure green color
D. Ignore soil-test results
Answer: B
Rationale: BMPs emphasize science-based nutrient management rather than
routine overapplication.
9. Nitrogen losses through leaching are most likely when:
A. Fertilizer is applied properly
B. Excess soluble nitrogen moves below the root zone
C. Turf actively absorbs all nutrients
D. Soil is frozen
Answer: B
Rationale: Leaching occurs when water carries nutrients beyond plant uptake
zones.
10. Case: A heavy rainstorm occurs shortly after fertilizer application. The
greatest concern is:
A. Improved nutrient retention
B. Increased nutrient runoff and leaching
C. Reduced irrigation needs only
D. Increased root density immediately
Answer: B
Rationale: Heavy rainfall can transport nutrients into groundwater and surface
waters.
