Fertilizer Density Scale for Dry/Granular Fertilizers

Fertilizer Density Scale – Frequently Asked Questions

What is a Fertilizer Density Scale?
A fertilizer density scale is a simple tool designed to measure the bulk density of dry granular fertilizers. By filling the container and weighing it, you can quickly determine the fertilizer’s density in pounds per cubic foot (lb/ft³) or kilograms per cubic meter (kg/m³). Knowing fertilizer density is essential for properly calibrating spreaders and ensuring even application in the field.

How to Use the Density Scale for Fertilizer?

1. Fill the scale’s container with the fertilizer you want to measure.

2. Level off the top so it’s flush with the container rim.

3. Balance the scale until the level bubble in the level indicator is centered.

4. The result gives you the bulk density reading. Once you know the density, you can reference calibration charts or input the value into your spreader settings for accurate application rates.

Do I Need a Fertilizer Density Scale?
If you’re applying granular fertilizers, a density scale is highly recommended. Fertilizer products vary in density depending on their formulation, granule size, and even moisture content. Using a density scale ensures your spreader is properly calibrated, reducing the risk of over-application (wasting product and harming crops) or under-application (leading to poor crop performance).
