Default Here is the way I'm calculating

Hello Luches. Thank you very much for the valuable information.

Bellow is the way I'm calculating the NPK Recipe for the example of the University of Florida. I write this in order you please to guide me in my calculations

N: 2*14.01*666/236.17 [Ca(NO3)2*4H2O] + 14.01*331/101.1 [KNO3]
= 124.88 ppm vs. 150 ppm you calculated

P: 30.97*250/136.09 [KH2PO4]
= 56.89 ppm vs. 57 ppm you calculated

K: 39.1*331/101.1 [KNO3] + 39.1*250/136.09 [KH2PO4]
= 199.84 ppm vs 200 ppm you calculated

Mg: 24.305*505/246.51 [MgSO4*7H2O]
= 49.79 ppm vs 50 ppm you calculated

Ca: 40.078*94/219.08 [CaCl2*6H2O]
= 17.19 ppm vs 15 ppm you calculated

Cl: 2*35.453*94/219.08 [CaCl2*6H2O]
= 30.42 ppm vs 60 ppm you calculated


Could you plese help me to improve my calculations?


My best.
