Title: Fertilizer Statistics Methodology


1
Fertilizer StatisticsMethodology
Robert Mayo Senior Statistician FAO Statistics
Division UNECE/FAO/Eurostat Workshop on
Environment Statistics (Budva, Montenegro, May
2013)
2
The importance of fertilizers and fertilizer
statistics and indicators
  • Environmental impacts
  • Development of production capacities
  • Production, imports and exports
  • Deliveries
  • Stocks
  • Use in agriculture
  • Prices.

3
Essential nutrients
  • Large quantities of Nitrogen, Phosphorus,
    Potassium
  • Smaller quantities of Sulphur, Calcium,
    Magnesium
  • Very small quantities of Iron, zinc, manganese,
    copper, boron, molybdenum and chlorine.

4
Terminology
  • Nitrogen N,
  • Phosphates P or P205,
  • Potash K or K2O,
  • Calcium- CaO or Ca,
  • Magnesium - MgO or Mg.

5
Classification
  • Straight fertilizers N, P, or K
  • Compound fertilizers
  • NP compounds
  • NK compounds
  • PK compounds
  • NPK compounds.

6
Essential elements
  • Carbon (C), Hydrogen (H), Oxygen (O)
  • Primary nutrients Nitrogen (N), Phosphorus
    (P205), Potassium (K20)
  • Secondary nutrients Sulphur (S), Calcium (CaO),
    Magnesium (MgO)
  • Micronutrients Boron (B), Copper (Cu), Iron
    (Fe), Zinc (Zn), Manganese (Mn), Molybdenum
    (Mo), Chlorine (Cl)

7
Conversion factors for major nutrients
P205 x 0.4364 P P x 2.2919 P205
K20 x 0.8302 K K x 1.2046 K20
CaO x 0.7147 Ca Ca x 1.3992 CaO
Mgo x 0.6030 Mg Mg x 1.6582 MgO
8
Commonly used straight nitrogenous fertilizers
  • Straight Nitrogenous Fertilizers
    N N
  • Ammonium sulphate
    21 20 - 21
  • Ammonium nitrate
    33.5 30 - 35
  • Ammonium sulphate nitrate
    26
  • Calcium ammonium nitrate (CAN)
    26 20.5 - 30
  • Sodium nitrate
    16
  • Calcium nitrate
    15.5
  • Urea
    46 44 -
    46
  • Anhydrous ammonia (direct application)
    82
  • Aqua ammonia
    20.5 10 - 30
  • Urea ammonium nitrate
    32 26 32
  • Ammonium chloride
    25

9
Commonly used straight phosphatic fertilizers
  • Straight Phosphatic Fertilizers
    P205 P205
  • Single superphosphate (SSP) 18
    16 - 22
  • Concentrated superphosphate 30 or
    32 23 - 39
  • Triple superphosphate (TSP) 46
    45 - 48
  • Basic slag
    14
    8 - 18
  • Ground rock phosphate (direct application)
    30 23 - 35
  • Fused magnesium phosphate 20
    19 - 20

10
Commonly used straight potassic fertilizers
  • Straight Potassic Fertilizers
    K20 K20
  • Potassium chloride (muriate of potash) 60 59
    - 61
  • Potassium chloride with magnesium
    40 39 - 41
  • Potassium sulphate
    50 48 - 52
  • Potassium magnesium sulphate
    22 or 30 21 - 30
  • Ammonium Phosphates Examples of grades
  • Diammonium phosphate (DAP)
    1846-0
  • Monoammonium phosphate (MAP)
    11-52-0 11- (50-55) - 0
  • Ammonium polyphosprate
    10-34-0

11
Commonly used potassium nitrate fertilizers
  • Potassium nitrate 13 0
    - 47
  • NP, PK, NK and NPK compounds Numerous grades,
    for example

  • 20-20-0, 16-20-0, 13-13-21,

  • 15-15-15, 17-17-17, 12-24-12,

  • 20-10-10, 23-23-0, 25-5-5.

12
Nutrient content and fertilizer grade
  • ammonium sulphate has 21 N
  • 100 kg of ammonium sulphate product
    contains 21 kg N.
  • superphosphate has 18 P205
  • 100 kg of single superphosphate product
    contains 18 kg P205
  • potassium chloride contains 60 K20
  • 100 kg of potassium chloride product
    contains 60 kg K20.

13
Nutrient content and fertilizer grade
  • For example, diammonium phosphate containing 18
    N and 46 P205 is expressed as 18-46-0.
  • A compound fertilizer 12-6-6 contains 12 kg N,
    6kg of P205 and 6kg of K20.
  • The "nutrient ratio" refers to the ratios of the
    three nutrient analyses e.g. the 12-6-6
    fertilizer referred to above has a 211 ratio.

14
Time periods
  • No standard time period for reporting fertilizer
    statistics
  • Calendar year basis
  • Split year basis - July/June
  • Other time periods used
  • Use of a standard, calendar year (January to
    December) advised. This provides possibility to
    relate the fertilizer consumption to agricultural
    production, yield, etc.
