We cannot know how much Nitrogen you are applying to the grass without knowing how large of an area your 500 gallon sprayer is covering when using the Peters Professional 20-20-20. There are details on solubility and N ppm on the product info sheet here. We recommend a soil test for the best results to insure you are not applying too much or too little of any of the macro-nutrients (N-P-K) needed for your lawn.
After reviewing the Product Information Sheet of Peters Professional 20 - 20 - 20 General Purpose Fertilizer, it shows that 1 tsp per gallon of water would be for approximately 238 ppm. It seems to get closer to the 150 ppm, you would need to be closer to a 1/2 tsp per gallon of water. We would recommend contacting the manufacturer directly to confirm. Everris can be reached at 800-492-8255.
The mixing ratio for Peters Professional 20-20-20 General Purpose Fertilizer is 1 tsp per gallon of water. It is recommended that you fill your tank up half way, put the product in, fill the tank up the rest of the way and agitate. This should not clog your sprayer because the product will dissolve in water. It is not recommended to leave a mixed solution inside of your sprayer. Application rates depend solely on the desired ppm of desired Nitrogen. Please read over the Product Information Sheet for further assistance.
How much of a fertilizer such as the Peters Professional 20-20-20 General Purpose Fertilizer that you use will depend upon the amount of the nutrients (usually Nitrogen) you want to apply to your target plants.

It is labeled for all annuals, perennials, fruit trees, and vegetables including: Daisies, Hibiscus, Impatiens, Mums, Pansies, Peppers, Petunias, Roses, and Tomatoes.

There are two different tables to check your rates for the Peters Professional 20-20-20 General Purpose Fertilzer on the information sheet here. The first table gives you the amount of product needed to make 1 gallon of product at the desired rates for your injection system ratio. So if you wanted 200 ppm N and you are using a 1:100 system, then you would use 13.5 lbs of the 20-20-20 to make 1 gallon of concentrate for your system. The second table gives you the gallons of water needed, so for 200 ppm and mixing an entire bag to get close to 200 gallons would be diluted a 25 bag in 197.5 gallons of water.
