FERTILIZER ANALYSIS

DETERMINATION OF POTASSIUM AND MAGNESIUM

Why we need potassium and magnesium?

POTASSIUM - provide the ionic environment for metabolic process in cytosol.(growth regulation)

- potassium ions (K+) for protein synthesis and opening and closing of stomata.

MAGNESIUM - part of chlorophyll in plant for photosynthesis

METHOD  Method for the determination of magnesium

Determination of water-soluble magnesium content (MgO) Principle

Magnesium in magnesium sulphate fertilizers is extracted in boiling water and the magnesium content determined by atomic absorption spectrophotometer.

Reference: MS 417: Part 6: 1994

PROCEDURE•Sample preparation

-registration

-drying

-grinding

•Weigh the sample•Add distilled water and HCl

Digest the solution using hot plate at boiling point around 20minutes

Leave to cool Transfer into volumetric flask and dilute to

the mark (250ml) Mixed the solution and filter in plastic vial

Further dilution(100ml) Add strontium nitrate(5ml) and dilute to the

mark To remove phosphate from magnesium and

calcium and prevent interference from other elements

Preparation for Atomic Absorption Spectrophotometer Standard stock solution

- Potassium dihydrogen sulphate solution- Magnesium sulphate solution

For 1000ppm,weigh 4.3928g. Dry in oven for 2 hours Undergo further dilution(m1v1=m2v2) 0, 0.25, 0.5, 0.75, 1.00 and 1.25 ppm

Pre-calibrate the AAS with standard stock solution

Run the AAS Then, we can determine the concentration

of the solution

DETERMINATION OF PHOSPHORUS

Why phosphorus important to plant?

• Essential to stimulate early plant growth and hastens the maturity.

• Development of root health.• Classified as macronutrient.

Methodology:• molybdovanadate method (yellow method).Reference:•MS 417: Part 4: 1994Apparatus:Spectrophotometer.Principle:•Amount of light transmitted (yellow colour) dependent on the concentration of phosphorus. •Spectophotometric absorption curve from known standard phosphorus solutions determined in unknown solution.

Standard stock solution: Potassium dihydrogen phosphate (4.3928g in 1L) 1000ppm 100ppm (0ppm 2ppm 4ppm 8ppm 10ppm)Reagent used: Molybdovanadate reagent: Ammonium molybdate (100ml)

mixed together with ammonium vanadate (150ml).

Aqua regia: Mixing the HCl & HNO3 together.

PROCEDURE Sample preparation and

weigh the samples (fertilizer)

Add distilled water.

Add 10ml HCl and 5ml HNO3 and boil.

transfer into volumetric flask.

Mark-up with distilled water then filter.

1ml of sample solution is pipette into 100ml volumetric flask.

Add Molybdovanadate reagent and diluted to the mark with distilled water.

prepare calibration standard (0,2,4,6 & 8 ppm) from the stock solution (1000ppm) and take

reading after 30 minutes.

Determine phosphate at acidic colour at pH ± 2.6 Double acid method is used. We put HCl and HNO3 to convert all polyphosphate (P2O7) to

orthophosphate (PO43-).

phosphate + metavanadate = phosphomolybdate acid + water. (yellow colour)

INTRODUCTION

INDUCTIVE COUPLED PLASMA (ICP)

measures the light emitted at element-specific characteristic wavelengths from thermally excited analyte ions . 

 light emitted is separated and measured in a spectrometer, yielding an intensity measurement that can be converted to an elemental concentration by comparison with calibration standards.
