How do you calculate the gallons of product used?

To determine the gallons of product used, you need to compare the initial amount of product available in the tank with the amount still present after application. The calculation involves subtracting the remaining gallons in the tank from the initial gallons. This allows you to find out how much product has been used during the application process.

The initial gallons represent the total amount of product before any application, while the remaining gallons indicate how much product is left after usage. By subtracting the two, you accurately identify the quantity of product that has been applied. This method is straightforward and provides a clear and direct understanding of product use, which is essential for effective application and management of fertilizer resources.
