The Hoagland solution is a hydroponic nutrient solution that was developed by Hoagland and Arnon in 1933 and is one of the most popular solution compositions for growing plants (in the scientific world at least). The Hoagland solution provides every nutrient necessary for plant growth and is appropriate for the growth of a large variety of plant species. The solution described by Hoagland in 1933 has been modified several times (mainly to add iron chelates and the like), but the original concentrations for each element are shown below.

  • N 210 ppm
  • K 235 ppm
  • Ca 200 ppm
  • P 31 ppm
  • S 64 ppm
  • Mg 48 ppm
  • B 0.5 ppm
  • Fe 1 to 5 ppm
  • Mn 0.5 ppm
  • Zn 0.05 ppm
  • Cu 0.02 ppm
  • Mo 0.01 ppm

The Hoagland solution has a lot of N and K so it is very well suited for the development of large plants like Tomato and Bell Pepper. However, the solution is very good for the growth of plants with lower nutrient demands such as lettuce and aquatic plants with the further dilution of the preparation to 1/4 or 1/5. Hoagland solution must be made from 7stock.

  1. Potassium nitrate(KNO3)
  2. Magnesium sulphate heptahydrate, MgSO4•7H2O, and potassium dihydrogen phosphate (Potassium phosphate monobasic), KH2PO4
  3. Iron EDTA or Iron chelate, Fe-EDTA
  4. Boric Acid, H3BO3
  5. Copper Sulfate, CuSO4
  6. Zinc sulfate heptahydrate, ZnSO4•7H2O
  7. Manganese chloride, MnCl2•4H2O
  8. Sodium molybdate, Na2MoO4•2H2O,
  9. Calcium nitrate, Ca(NO3)2•4H2O. Last solution must be added as final.

Na2MoO4•2H2O 0.12 g/L 1
Phosphate
1M KH2PO4 (pH to 6.0) 136 g/L 0.5
  1. Make up stock solutions and store in separate bottles with appropriate label.
  2. Add each component to 800 mL deionized water then fill to 1 L.
  3. After the solution is mixed, it is ready to water plants.
