How to Calibrate Your Fertilizer Spreader for Maximum Efficiency | Newton Crouch


Best Proper calibration of a fertilizer spreader is essential for achieving consistent, accurate application rates. Applying too much fertilizer wastes product and can harm plants and the environment, while too little can reduce yield. Calibration ensures every pound of material is spread evenly across your field.

Start by checking the manufacturer’s manual for recommended settings based on your spreader type and fertilizer blend. Next, perform a spread pattern test to measure how much fertilizer is being applied per square foot. Adjust the gate openings and ground speed as needed until the actual application rate matches your target rate.

For spinner spreaders, ensure both discs rotate at the same speed and that the blades are properly aligned to achieve an even spread pattern. Airflow and spinner RPMs can influence accuracy—especially with granular products of varying size or density.

Recheck calibration at the beginning of each season, after changing materials, or if spreading patterns seem inconsistent. Consistent calibration improves fertilizer use efficiency, saves input costs, and supports more uniform crop growth.

To get the most out of your fertilizer applications, choose a spreader with precision agriculture technology that automates rate control for even more accurate results.Practices to Stay in Calibrati
