O A golf course superintendent prepared a liquid fertilizer for use on the course's fairways. The composition of the solution was 240 ppm N - 45 ppm P- 80 ppm K (remember that I ppm in solution equals 1 mg/L of solution). The fertilizer sources used to prepare the solution were ammonium sulfate (21-0-0), monoammonium phosphate (11-52-0), and potassium nitrate (13-0-45). How many grams of each fertilizer were needed to produce 5000 liters of this solution?

Question
1.) A golf course superintendent prepared a liquid fertilizer for use on the course's fairways. The composition of the solution was 240 ppm N - 45 ppm P - 80 ppm K (remember that I ppm in solution equals 1 mg/L of solution). The fertilizer sources used to prepare the solution were ammonium sulfate (21-0-0), monoammonium phosphate (11-52-0), and potassium nitrate (13-0-45). How many grams of each fertilizer were needed to produce 5000 liters of this solution? 2.) A canola grower wanted to apply 155 lbs N/A and 55 Ibs K/A at the start of the growing season. Which of the following options would be the most economical: 1) apply all the K and some of the N as 13-0-45 (potassium nitrate), applying the additional needed N as 46-0-0, or 2) apply all the N as 46-0-0 and all the K as 0-0-50-17S (potassium sulfate)? Prices: 46-0-0 ($525/ton), 13-0-45 ($575/ton), 0-0-50-17S ($535/ton). Compute the cost per acre with each option. The above are English tons which equal 2000 lbs.
