IV. FINAL RESULTS
Calcium Content = 0.4 x Titration Value B = ppm Ca
Magnesium Content = 0.24 (Value A - Value B) = ppm Mg
Multiply the results by 2 to obtain the content in pounds per acre.
EXAMPLE:
Titration Value A is 640 ppm CaCO
3
Titration Value B is 520 ppm CaCO
3
Calcium = 0.4 x 520 = 208 ppm Ca
= 208 x 2 = 416 lb/acre Ca
Magnesium = 0.24 (640 - 520)
= 0.24 x 120 = 29 ppm Mg
= 29 x 2 = 58 lb/acre Mg
