- Calculations and Nutrient Management
Introduction
The Tennessee Fertilizer Applicator Certification Exam is designed to ensure that
professionals managing plant nutrients possess the critical knowledge required for
safe, effective, and legal application. This assessment evaluates a candidate’s
understanding of soil fertility, nutrient interactions, and state-specific regulatory
compliance. Through a combination of multiple-choice and scenario-based
questions, the exam tests the ability to interpret labels, calibrate machinery, and
,protect Tennessee’s water resources from runoff. Emphasis is placed on real-
world application and ethical decision-making, ensuring that certified applicators
can optimize crop or turf performance while minimizing environmental impact
through precise nutrient management planning and adherence to best
management practices.
Section One: Questions 1–100
1. Under the Tennessee Fertilizer Law, which state entity is primarily
responsible for the regulation and licensing of fertilizer distribution?
A. Tennessee Department of Environment and Conservation
B. University of Tennessee Extension
C. Tennessee Department of Agriculture
D. Tennessee Farm Bureau
🟢 C. Tennessee Department of Agriculture
🔴 Explanation: The Tennessee Department of Agriculture (TDA) holds the
regulatory authority to enforce state fertilizer laws, including registration, labeling,
and inspection.
2. A fertilizer label shows a guaranteed analysis of 10-20-10. What is the
percentage of water-soluble potash (K2O) in this product?
,A. 10%
B. 20%
C. 5%
D. 40%
🟢 A. 10%
🔴 Explanation: In a standard N-P-K fertilizer grade, the third number represents
the percentage by weight of soluble potash (K2O).
3. Which primary plant nutrient is most prone to leaching in sandy soils during
heavy rainfall?
A. Phosphorus
B. Nitrogen
C. Potassium
D. Calcium
🟢 B. Nitrogen
🔴 Explanation: Nitrogen, particularly in the nitrate form, is highly mobile in soil
water and easily moves downward below the root zone in porous soils.
4. If a soil test indicates a pH of 5.2, which material should be applied to raise
the pH to a more neutral range?
, A. Elemental sulfur
B. Aluminum sulfate
C. Ammonium nitrate
D. Agricultural limestone
🟢 D. Agricultural limestone
🔴 Explanation: Agricultural limestone (calcium carbonate) is the standard
material used to neutralize soil acidity and increase pH levels.
5. A 50-pound bag of 24-0-12 fertilizer contains how many pounds of actual
Nitrogen?
A. 24 lbs
B. 12 lbs
C. 6 lbs
D. 50 lbs
🟢 B. 12 lbs
🔴 Explanation: Calculation: 50 lbs (total weight) x 0.24 (24% Nitrogen) = 12
pounds of Nitrogen.
6. Which nutrient is considered a secondary macronutrient?
