One acre of tobacco will need anywhere from 200 pounds to 250 pounds of fertilizer. How much depends on the nutrients needed by your crop and soil.
60 pounds of fertilizer, spread over the 12,000 square foot lawn, an acre is 43,560 square feet or 220 lbs +/-.
To find out how much fertilizer is needed for 120 square feet, first, determine the area in acres. One acre is equal to 43,560 square feet, so 120 square feet is 0.00275 acres (120 ÷ 43,560). Then, multiply 24 gallons by the acreage to find the amount needed for 120 square feet, which is 0.066 gallons (24 × 0.00275).

If your aplication rate is 300 lbs per acre of 13/13/13, you need 100 lbs of 13/13/13.
The 0-11-52 means 0% Nitrogen (N), 11% Phosphorous (P) and 52 Potassium (K). The ratio of P to K that you need is 35/60 or ~ 1/2, but the P to K ratio of your "fertilizer" is 11/52 or ~ 1/5. You should get a fertilizer with a ratio more in line with what you need or expect to have to apply multiple fertilizers. Here is how you work out how much to apply per acre for each nutrient. Using Potassium as an example lbs to apply per acre = <lbs nutrient required per acre> / <% nutrient> lbs K to apply per acre = 60 / 0.52 ~ 120 lbs But like I said you would not get the correct amount of P with this fertilizer.
* growing both acres in the same weather, preferably by the same farmer and even side by side * adding another control of an acre grown with the standard fertilizer to see if the new one is better * either adding several more plots with the same treatment or dividing the acre into several smaller plots to increase sample size * repeat the experiment in several different countries/corn varieties/ farmers/weather/ seasons
