Which federal agency regulates the labeling and registration of fertilizers that contain pesticide claims in the United States?
Answer: EPA
The EPA regulates any product with pesticidal claims under FIFRA, and fertilizer-pesticide combination products must be registered with the EPA before sale.
When a worker experiences skin contact with anhydrous ammonia fertilizer, the immediate first aid response is to:
Answer: Flush with large amounts of water for at least 15–20 minutes
Anhydrous ammonia causes severe alkali burns; flushing immediately with large amounts of water dilutes and removes the chemical to minimize tissue damage.
The nitrogen loss process called volatilization is most significant when urea fertilizer is applied to:
Answer: Warm, moist soils with a high pH and no incorporation
Urease enzyme activity is highest on warm, moist, high-pH soils, rapidly converting urea to ammonia gas that escapes to the atmosphere before incorporation.
Which type of soil test result would indicate the LOWEST risk of phosphorus runoff loss?
Answer: Soil phosphorus at 15 ppm on a well-structured silt loam with buffer strips
Low soil phosphorus levels, good soil structure, and vegetated buffer strips all combine to minimize phosphorus runoff risk to adjacent waterways.
OSHA's Hazard Communication Standard (HazCom) requires that workers who handle fertilizers have access to:
Answer: Safety Data Sheets and receive training on chemical hazards
HazCom (29 CFR 1910.1200) requires employers to provide SDS for all hazardous chemicals and train employees on how to interpret and use hazard information.
Which nutrient management practice most effectively reduces the risk of nitrate leaching during fall fertilizer applications?
Answer: Using nitrification inhibitors and split-applying nitrogen closer to crop need
Nitrification inhibitors slow the conversion of ammonium to leachable nitrate, and split applications time nitrogen delivery closer to when crops can take it up.
In the context of fertilizer safety, a 'secondary containment' system is designed to:
Answer: Capture and contain spills or leaks from primary storage tanks
Secondary containment (e.g., berms, dikes, catch basins) surrounds primary storage containers to prevent spills from reaching soil or water resources.
