If the swath width is 5 feet, and 3 pounds of 10-0-10 are applied over a distance of 100 feet, what is the nitrogen application rate?

To determine the nitrogen application rate, it's essential to understand the concentration of nitrogen in the fertilizer mix, the amount applied, and the area covered.

In this scenario, the fertilizer used is 10-0-10, which indicates that it contains 10% nitrogen. Therefore, when you apply 3 pounds of the fertilizer, the amount of nitrogen being applied is calculated as follows:

Amount of nitrogen = Total fertilizer applied × (Nitrogen percentage / 100)

Substituting the values gives:

Amount of nitrogen = 3 lbs × (10 / 100) = 0.3 lbs of nitrogen.

Next, we need to calculate the area that the nitrogen is applied over. The width of the swath is given as 5 feet, and the distance over which the fertilizer is applied is 100 feet. Therefore, the area can be calculated as:

Area = Width × Length

Area = 5 feet × 100 feet = 500 square feet.

To find the application rate in pounds per 1,000 square feet, we use the formula:

Application rate = (Amount of nitrogen / Area) × 1,000 square feet.

Substituting the values gives:

Application rate = (0.3 lbs N /
