Calibrating Your Spreader for Accurate Application of Fertilizer

Calibrating your spreader is an essential step in ensuring accurate and efficient application of fertilizer in your garden. By properly calibrating your spreader, you can avoid over or under-applying fertilizer, which can lead to uneven growth and potential damage to your plants.

Step 1: Determine the Application Rate

The first step in calibrating your spreader is to determine the desired application rate for your fertilizer. This information can usually be found on the fertilizer packaging or obtained from the manufacturer. The application rate is typically given in pounds per 1,000 square feet.

Step 2: Measure the Spreader’s Distribution Width

Next, you need to measure the distribution width of your spreader. This refers to the width of the fertilizer pattern that the spreader creates as it dispenses the fertilizer. To measure the distribution width, simply walk a straight line while operating the spreader and measure the width of the fertilizer pattern left behind.

Step 3: Calculate the Spreader Setting

Using the application rate and distribution width, you can now calculate the appropriate spreader setting for accurate fertilizer application. This can be done using a simple formula:

Spreader Setting = (Application Rate / Distribution Width) x 100

For example, if your desired application rate is 2 pounds per 1,000 square feet and the measured distribution width is 6 feet, the spreader setting would be:

(2 / 6) x 100 = 33.33

Therefore, you would set your spreader to 33.33 for accurate application of the fertilizer.

Step 4: Test and Adjust

Once you have calculated the spreader setting, it is important to test it before applying fertilizer to your entire garden. Fill the spreader with a known quantity of fertilizer and walk a predetermined distance, such as 100 feet, while operating the spreader at the calculated setting. Afterward, measure the amount of fertilizer remaining in the spreader to ensure that it matches the expected amount based on the spreader setting.

If the amount of fertilizer dispensed is too low or too high, you may need to adjust the spreader setting accordingly. Repeat the test and adjustment process until you achieve the desired application rate.

By following these steps and calibrating your spreader, you can ensure accurate and efficient application of fertilizer in your garden, promoting healthy plant growth and maximizing the benefits of your fertilizer.
