17-17-17 Fertilizer Application Rate

The application rate can vary depending on the amount of fertilizer your lawn or plants need.

So in order to get an exact number, it’s best to do a soil test.

But to give you a number, you can use the industry-standard, which is 1lb of fertilizer per 1000 sq. ft., and divide it by the amount of nitrogen you need, which in this case is 17%.

When doing the calculation, make sure to convert the number of your fertilizer into decimals. 

For example 17% Nitrogen = 0.17 Nitrogen

You will calculated like this:

(1.0 lb of nitrogen x 1000 sq ft) ÷ 0.17 = 5.8 lb of 17-17-17 fertilizer to supply 1000 sq. ft of nitrogen.

So if you have 3000 sq ft of lawn, all you have to do is multiply the 5.8 lb of fertilizer x the sq ft of lawn.

For example: 

3000/1000 = 3

5.8 x 3 = 17.4

So in order to fertilize a 3000 sq ft lawn, you will need to spread 17.4lb of fertilizer to meet the nitrogen requirements. 

To determine the Phosphorus and Potassium, multiply 5.8 lb fertilizer per 1000 sq ft, by the percentage of Phosphorus and Potassium.

For example:

5.8 lb fertilizer x 0.17 Phosphorus/Potassium = 0.98

How Many Pounds of 17-17-17 Fertilizer per Acre?

You will first need to determine how much fertilizer you will use per 1000 sq ft. In the previous example, we determined the amount needed for 1000 sq ft was 5.8 lb fertilizer.

There are 43,560 sq ft in an acre, so all you have to do is multiply that by 5.8 lb and divide by 1000. 

For example:

(5.8 lb fertilizer x 43,560) ÷ 1000 = 252 lb fertilizer.
