No. Let’s begin by saying that people generally use a fertilizer spreader for distributing powdered or granular fertilizer, while spreaders for seeds are meant to do the same with any seeds.

Furthermore, people can use a fertilizer one for both dry and liquid products, while seed spreaders are only for dry. So, if you want to use a liquid, you should choose a machine for fertilizer.

Both spreaders have some settings you can adjust to ensure an even distribution pattern, but they work differently. These two types are available in handheld or tow-behind models. Besides, a spreader for seed can be either hand-operated or motorized, while such machines for fertilizer are usually motorized.

What are the differences in the design of these spreaders?

Of course, there are several key differences between these two types. For example, it is essential to consider the type of spreading mechanism, as it will influence the accuracy and efficiency.

Seed spreaders are built to precisely distribute seed at an even rate. You can find fertilizer spreaders in two types: broadcast and drop, while seed spreaders are almost always of the drop type. Drop-type fertilizer spreaders have the advantage of being able to apply fertilizer in a band, thus avoiding seed bed preparation problems and potential seedling injury.

Besides, seed spreaders typically have a smaller hopper and drop hole than spreaders for fertilizer. As a result the seeds are not damaged as they are being dispensed. Some seed spreaders also have an agitator to help keep the seeds mixed and flowing evenly.

There are design differences between these two types of spreaders. For example, fertilizer spreaders must be designed to handle the corrosive nature of fertilizers. Therefore, they are typically made of materials, including stainless or powder-coated steel. On the other hand, spreaders for seed can be made of various materials like plastic or aluminum since seeds are not corrosive.

Finally, there are differences in how spreaders are calibrated. Spreaders for fertilizer are typically calibrated in pounds per acre, while seed spreaders are calibrated in pounds per 1,000 square feet. Again, it is because fertilizer application rates are typically much higher than seed application rates.

Fertilizer spreaders

Do fertilizer and seed spreaders have the same settings?

No, fertilizer and seed spreaders have different settings. Fertilizer spreaders typically have a higher setting than seed spreaders. If you were to use the same setting for both, you would have too much fertilizer in some areas and not enough in others. The reason is that fertilizer is heavier than seed and must be spread at a higher rate. Seed spreaders usually have a lower setting, so the seed is not dispersed too thickly. Always check the manufacturer’s instructions to ensure you are using the correct setting.

Are there any spreaders for both: seeds and fertilizers?

Yes, some spreaders can be used for both seeds and fertilizers. However, these spreaders are usually more extensive and cost more than for spreading only one type of material.

In any case, however, it is needed to note that you will need to adjust some particular settings to accommodate the different materials. For example, when you want to spread seeds, you should use a lower setting than if speaking about a spreader for fertilizer.

Before you are going to purchase, a good idea is to read the label of products carefully to see if you can use a particular model for both purposes.
