Per the CoRoN 18-3-6 Plus 0.5% Fe product label: For cool season grasses you should be using 3.75-4.25 lbs of nitrogen per 1000 sq/ft per year. Many customers break down their fertilizer applications into 6-8 applications per year throughout the growing season. If we go with 6 times a year and a desired rate of 4 lbs of nitrogen per 1000 sq/ft per year, you would be looking at roughly 45 oz per 1000 sq/ft per each of the 6 applications. If you only have 200 sq/ft of lawn to treat then you would only need roughly 9 oz to that area in likely ½ -¾ gallon of water at most. You typically use 1-2 gallons of water per 1000 sq/ft, so since your area is much smaller than that you should not be using that high of a water volume.
Generally speaking you would typically apply 22 ounces or so of CoRoN 18-3-6 Plus 0.5% Fe in 2-5 gallons of water per 1000 square feet. The specific amount of product is going to vary based on the type of grass you are treating, but generally 22 ounces per 1000 square feet is the average application.
