I know that I did this a few years back in school but the know how and formula for calculating the analysis of a liquid fertilizer blend has slipped my mind. We had 1400 gallons of 9-18-4-3S-.5Zn starter in a tank and pumped 4650 gallons of 28-0-0-4S in with it. How do I calculate the analysis of my new "blend?" Thanks
