Effectiveness of liming material is primarily influenced by

  1. Purity: Any impurities in the lime will reduce its ability to neutralize acidity; such as sand, rocks, clay, etc.
  2. Particle size/Fineness: Large particles react more slowly and less completely than fine particles.

    Particle Size Efficiency Rate (%)
    larger than 4 mesh 0
    4-8 mesh 10
    8-20 mesh 20
    20-60 mesh 60
    60-80 mesh 80
    100 mesh 100
  3. Neutralizing value (CCE*) calcium carbonate equivalent of the pure forms of some commonly used liming materials

    Liming materials Neutralizing Value
    CaO 179
    Ca(OH)2 136
    CaMg(CO3)2 109
    CaCO3 100
    CaSiO3 86

* Calcium Carbonate Equivalent (CCE) is the neutralizing value of a liming material compared to pure calcium carbonate. A CCE of 100% indicates that a material will neutralize the same amount of acidity per pound as pure calcium carbonate.

 

Note: AgriCal has the neutralizing value of 106 min. and particle size of 200 mesh, thus provides maximum liming effectiveness.

pH is a scale that chemists use to measure acidity. Values < 7 are considered acidic, values > 7 are alkaline and 7 is neutral. Most plants can tolerate a wide pH range in solution culture, but they cannot tolerate a wide range of acidity in the soil... Read More...
