PART B
PROCEDURE FOR DRAWAL OF SAMPLE OF SOIL CARBON ENHANCER
The Inspector shall draw any sample of organic Carbon Enhancer in accordance with procedure of drawal
mentioned under Part A of Schedule -II.
PART C
1. Method of Analysis of Fermanted Organic Manure
(i). Estimation of pH: As per procedure specified in Part D of Schedule IV at serial number1.
(ii). Estimation of moisture: As per procedure specified in Part D of Schedule IV at serial number2
(iii). Estimation of conductivity: As per procedure specified in Part D of Schedule IV at serial number14
(iv). Estimation Organic Carbon: As per procedure specified in Part D of Schedule IV at serial number5
(v). Estimation of Cadmium, Copper, Chromium, Lead, Nickel and zinc: As per procedure specified in Part D of
Schedule IV at serial number 10
(vi). Estimation of Mercury: As per procedure specified in Part D of Schedule IV at serial number11.
(vii). Esimation of Arsenic: As per procedure specified in Part D of Schedule IV at serial number12.
(viii). Pathogencity test: As per procedure specified in Part D of Schedule IV at serial number13
2. Methods of analysis of Liquid Fermented Organic Manure
Since the estimation on different parameters prescribed in Fertiliser Control Order has to be done on dry
weight basis, the sample has to be dried appropriately.
Drying of Sample
(A) To take 1000 ml of Liquid Fermented Organic Manure in 1 litre beaker and put @100 ml of Liquid Fermented
Organic Manure in a suitable beaker (3-5 of 500 ml) and oven dry the sample at 105° C for 7 hours. Switch off the
oven and re-operate it next day maintaining the same temperature for another 3-4 hours.
(B) To transfer the dry Liquid Fermented Organic Manure flakes from all beakers to another beaker and measure the
total weight of dried OCE - L per litre and use these dry flakes for estimation of Organic Carbon and heavy metals
while Electrical Conductivity, pH could be estimated from liquid sample following the Fertiliser Contro Order
protocols of testing.
1. Estimation of pH,-
(a). take 75 ml of sample and shake on a rotary shaker at 180 rpm for 2 hours.
(b). filter through Whatman paper number 1.
(c). determine pH of the filtrate by pH meter.
Reference: The Fertiliser (Control) Order 1985, Schedule IV: Part D-1.,
2. Estimation of Electric Conductivity,-
(a). take 20 ml of the sample and add 100 ml of distilled water to it to give a ratio of 1:5.
(b). stir the sample at rotary shaker at 180 rpm for about an hour.
(c). calibrate the conductivity meter by using 0.01 M potassium chloride solution.
(d). measure the conductivity of the unfiltered organic fertilizer suspension.
Reference: The Fertiliser (Control) Order 1985, in serial IV of Part D of Schedule IV.
3. Estimation of Total Organic Carbon
(a). accurately weigh 10 gm of dried representative sample (flakes) in a pre-weighed crucible.
(b). ignite the sample in a muffle furnace at 650 – 700°C for 8 hrs.
(c). cool to room temperature and keep in desiccator for 12 hrs and weigh the contents with crucible.
Calculation,-
Total Organic matter (TO) = Initial weight- final weight
--------------------------- x W
10 (weight of sample taken)
W - weight of dried flakes in 1000 ml water samples
Organic matter (%) = (TO /1000) x 100
Total Organic Carbon= Organic matter (%)
1.724
4. Estimation of Heavy Metal
(a). take 5.0 gm of sample in a conical flask and add 30 ml triacid mixture; cover it with a small glass funnel
for fluxing.
(b). digest the sample at 200°C on a hot plate till the volume is significantly reduced with a whitish residue.
After cooling, filter the sample with Whatman No. 42 filter paper and make up to 100 ml in a volumetric
flask.
(c). estimate the metal concentrations of Cd, Cu, Cr, Pb, Ni, Zn by flaming the standard solution and samples
using atomic absorption spectrophotometer (AAS) as per the procedure prescribed in serial 10 of Part D of
Schedule IV.
(d). the Arsenic and Mercury as per the in serial number 11 and 12 of Part D of Schedule IV.
