To find the amount of atrazine you'll be applying per acre, simply multiply the pounds per acre by the percentage of atrazine in the product Be sure to convert the percentage to a decimal. Example 2: Product contains 21 percent atrazine. You are app lying 2.2 pounds per acre. 0.21 (percent atrazine content) x 2.2 (application rate) = 0.46 pound atrazine. In this example, the 2.2 pound rate would result in .46 pound of atrazine being applied per acre. Through the company’s refores tation efforts, more than 120,000 acres of timber have been planted in the four-state area.
