Essential Elements:
Modern chemical fertilizers include one or more of the three elements most important in plant nutrition:
Nitrogen (N) - Phosphorus (P) - Potassium (K)In fact, with most fertilizers, the analysis of the approximate nutrient content is usually expressed as a percentage called the N.P.K. ratio. For example
Nitrogen (N) - Phosphorus (P) - Potassium (K) (N) (P) (K)Fowl manure is: 2.1: 1.6: 1.0Cow manure is: 1.0: 0.4: 0.5NPK 15.0: 15.0: 15.0 16.0: 16.0: 16.0 17.0: 17.0: 17.0 19.0: 19.0: 19.0 20.0: 20.0: 20.0MAP (Mono-Ammonium Phosphate) 11.0: 44.0: 0.0MAP (Mono-Ammonium Phosphate) AG 12.0: 52.0: 0.0MAP (Mono-Ammonium Phosphate) Tech. 12.0: 61.0: 0.0MKP (Potassium Phosphate Monobasic) 0.0: 52.0: 34.0Lawn Fertilizer or for leafy crops such as cabbages etc.
which take a lot of Nitrogen out of the soil: 17.0: 0.5: 5.0Water soluble fertilizers Thrive and Zest: 31.0: 5.0: 9.0Urea: 46.0: 0.0: 0.0
Elements of secondary importance: Sulphur (S) - Magnesium (Mg) - Calcium (Ca)
Other elements needed in small quantities that may be present in specially blended fertilizers include:
Silicon (Si) - Iron (Fe) - Chlorine (Cl)Elements in trace amounts may be: Boron (B) - Copper (Cu) - Manganese (Mn) - Molybdenum (Mo) - Zinc (Zn)
NITROGEN fertilizers are mostly obtained from synthetic ammonia, used either as a gas or in water solution, or converted into salts such as Ammonium Sulphate, Ammonium Nitrate, and Ammonium Phosphate; but packinghouse wastes, treated garbage, sewage, manure, and cottonseed meal are also common sources.
PHOSPHORUS fertilizers include Calcium Phosphate from phosphate rock or bones.
The water soluble Superphosphate and Triple Superphosphate are obtained by treatment of Calcium Phosphate with Sulphuric Acid and Phosphoric Acid respectively.
POTASSIUM fertilizers, namely Potassium Chloride and Potassium Sulphate, are mined from potash deposits.
Packaging:
Blended fertilizers are usually packaged in 50 kg bags but still only sold in large quantities. So we mainly ship in ISO Containers. Please check with us in early stage of negotiation.
