Fertilizer analysis guarantees are based on a minimum amount present on a per cent volume basis.

• A. False
• B. True
• C. Sometimes
• D. Not applicable

Answer: (A)

Fertilizer guarantees are stated as minimum percentages of nutrients by weight in the product. This means the label promises at least a certain percent of nitrogen, phosphorus (as P2O5), potassium (as K2O), etc., based on the product’s mass, not its volume. Using weight keeps the guarantee consistent no matter how densely or loosely the bag is packed or how much moisture the product contains. Volume would vary with density and moisture, making guarantees unreliable. Moisture content is usually listed separately, and the nutrient guarantees reflect the product’s dry-weight nutrient content. So the statement about guarantees being based on a minimum amount per cent volume is not correct.
