2. INTRODUCTION
DEFINATION ( SOIL )
• A NATURAL BODY OCCUR ON THE EARTH’S
SURFACE, SUPPORTING OR CAPABLE OF
SUPPORTING PLANTS AND CONSISTING OF
MINERAL AND ORGANIC MATERIALS. IT
CHARACTERIZED BY RELATED HORIZONS
RESULTING FROM THE INTERACTIONS OF
CLIMATE AND VEGETATION OR VARIOUS
PARENT MATERIAL OVER VARYING PERIODS
OF TIME AND MODIFIED BY LOCAL RELIEF.

3. SOIL
MINERAL SOIL
SEDENTARY

4. EXAMPLE OF SOIL

5. TYPES OF
ANALYSIS
DETERMINATION
OF AVAILABLE P
AND TOTAL P
DETERMINATION
OF SOIL PH
MOISTURE
(DRY & WET)
ELEMENTAL
ANALYSIS (EA)

6. WHY????
TO CHECK WHETHER THE SOIL
SUITABLE (VIABILITY) FOR PLANTATION
CHECK THE SOIL FERTILITY
CHECK THE CONTENT OF ELEMENTS
PRESENT IN SOIL

7. METHODOLOGY

8. DETERMINATION OF
AVAILABLE P
WEIGHT 2g OF
SAMPLE
ADD 20mL OF
0.01 N NH4Fl2
AND 0.03mL HCL
SHAKE FILTER
DILUTION
TAKE THE
READING USING
AAS

9. DETERMINATION OF TOTAL
PHOSPHORUS
FILTER AND CONTINUE WITH THE DILUTION
CHECK WITH PHOTOMETER
DIGEST FOR 2 HOURS AT 150-200 ˚C UNTIL THE COLOR CHANGE TO WHITE
LEAVE TO COOL & MAKE UP TO 100mL
WEIGHT 1g OF SOIL INTO THE DIGESTION TUBE
ADD 3mL A MIXTURE OF SULFURIC ACID & PERCHLORIC ACID.LEAVE FOR 2
HOURS

10. DETERMINATION OF SOIL PH

11. MOISTURE (WET & DRY)
WEIGHT 10g
OF SAMPLE
INTO
PORCELIN
DISH
HEAT IN THE
OEN FOR 2
HOURS
COOL IN
DESICCATOR
WEIGHT THE
SAMPLE AND
RECORD THE
DATA

12. ELEMENTAL ANALYSIS (EA)

13. RESULT &
CALCULATION

14. TOTAL P AND AVAILABLE P

15. PH

16. MOISTURE (WET & DRY)

17. • % MOISTURE
= MASS MOISTURE X100%
MASS SAMPLE

18. CONCLUSION
• THE AIM OF THE ANALYSIS OF SOIL IS TO
KNOW WHETHER THE SOIL SUITABLE OR NOT
FOR PLANTATION.
• THE SUITABLE PH FOR THE SOIL IS AROUND
4.3.
• THE AP AND TP ARE ANALYZE IN ORDER TO
KNOW THE NUMBER OF PHOSPHATE.
• THE SOIL IS NOT SUITABLE FOR PLANTATION
AS THE % OF MOSTURE IS HIGHER.
