Dry fertilizers are widely used in agriculture to provide essential nutrients for crop growth. The weight of dry fertilizers is a crucial factor in determining the spreader capacity and the amount of fertilizer required for application. This article delves into the weight of common dry fertilizers, factors affecting their weight, and the importance of considering weight in fertilizer management.
Key Facts
- Weight of Common Dry Fertilizers:
- Ammonium Sulfate (21-0-0): 60-64 lbs./cu. ft.
- Ammonium Nitrate (34-0-0): 58-62 lbs./cu. ft.
- Urea (46-0-0): 48-52 lbs./cu. ft.
- Diammonium Phosphate (18-14-0): 56-60 lbs./cu. ft.
- Ammonium Phosphate (16-20-0): 58-62 lbs./cu. ft.
- Coarse Muriate of Potash (0-0-60): 66-70 lbs./cu. ft.
- Factors Affecting Weight:
- Humidity: The weight of dry fertilizers can vary depending on the humidity levels. Higher humidity can increase the density of the fertilizer, resulting in slightly higher weights.
- Importance of Weight:
- Spreader Capacity: Knowing the weight of dry fertilizers is important for determining the capacity of spreaders. It helps in calculating the amount of fertilizer a spreader can hold and distribute effectively.

FAQs
What is the average weight of common dry fertilizers?
The average weight of common dry fertilizers ranges from 48 to 70 pounds per cubic foot, depending on the specific fertilizer and its composition.
Which dry fertilizer is the heaviest?
Coarse Muriate of Potash (0-0-60) is typically the heaviest common dry fertilizer, with a weight of 66-70 pounds per cubic foot.
Which dry fertilizer is the lightest?
Urea (46-0-0) is typically the lightest common dry fertilizer, with a weight of 48-52 pounds per cubic foot.
How does humidity affect the weight of dry fertilizers?
Higher humidity can increase the density of dry fertilizers, resulting in slightly higher weights. This is because water vapor in the air can be absorbed by the fertilizer particles, increasing their overall mass.
Why is it important to consider the weight of dry fertilizers?
Considering the weight of dry fertilizers is important for determining the capacity of spreaders and calculating the amount of fertilizer required for application. It also helps in optimizing fertilizer application rates and minimizing wastage.
How can I determine the weight of a specific dry fertilizer?
The weight of a specific dry fertilizer can be found in its product specifications or technical data sheet. It is typically expressed in pounds per cubic foot or kilograms per cubic meter.
What are some factors that can affect the weight of dry fertilizers?
Factors that can affect the weight of dry fertilizers include the chemical composition of the fertilizer, its physical properties, and the humidity levels.
How can I properly store dry fertilizers to maintain their weight and quality?
Dry fertilizers should be stored in a cool, dry place, away from direct sunlight and moisture. Proper storage helps prevent caking and degradation of the fertilizer, ensuring its weight and quality are maintained.
