Square Foot Advantage Calculator

It’s easy to calculate the cost-in-use advantages of fertilizer programs that are Driven by Duration. There are only four things you need to provide:

  1. The total square feet you fertilize (or average lawn size and number of lawns treated)
  2. The N content (%) in a bag of fertilizer used
  3. The rate (lbs./N per 1,000 sq. ft.) in each fertilizer application you’re currently making
  4. The price you pay for each 50-lb. bag

(It’s a bonus if you also know your labor and overhead costs per 1,000 sq. ft.)

You’ll be able to compare it to a single application of Spread it & Forget it, and three applications of other fertilizers that are Driven by Duration.
