Pick out the wrong statement.

• Nitrogen is normally supplied in fertiliser either in ammoniacal or the nitrate form, from which the soil takes it up in the form of ammonium ions or nitrate ions and forms amino acids.
• Calcium present in the fertiliser helps in correcting the soil acidity.
• Particle size range of a good grannular fertiliser is 10-15 mesh and it contains less moisture as compared to finely divided powder form of fertiliser.
• Ammonium nitrate fertiliser is obtained as a by-product in an integrated steel plant having by-product coke ovens.
