What is Topdress Calculator?
If you’re a lawn care professional or a homeowner looking to maintain your lawn, a Topdress Calculator can come in handy. It helps you determine the amount of topdressing material you need to apply to your lawn based on its size and the desired depth of coverage. In this article, we’ll discuss the Topdress Calculator, the formula it uses, how to use it, and some frequently asked questions.
The Formula Used in Topdress Calculator
The formula used in the Topdress Calculator is as follows:
TW = A * D/12 * 101.8
where TW is the Topdressing Weight (in pounds), A is the area to cover (in square feet), and D is the depth to fill (in inches).
For example, let’s say you want to topdress a lawn that is 1,000 square feet in size with a depth of 0.5 inches. Using the formula above, you can calculate the Topdressing Weight needed as follows:
TW = 1,000 * 0.5/12 * 101.8 = 424.17 pounds
Therefore, you would need 424.17 pounds of topdressing material to cover your lawn with a depth of 0.5 inches.
