Macro Nutrients-relative percentages
For those that feel more comfortable using the relative weight
percentages of N-P-K to caclulate the amount of a macro-nutrient in a
given chemical, I pulled these off a hydroponics site:
Ammonium Nitrate (NH4NO3) 34 - 0 - 0
Mono-potassium Phosphate (KH2PO4) 0 - 51.5 - 34
Calcium Nitrate (CaNO3) 15.5 - 0 - 0
Potassium Nitrate (KNO3) 13.75 - 0 - 46
Potassium Sulfate (K2SO4) 0 - 0 - 50
Potassium Chloride (KCl) 0 - 0 - 62
