objective

purpose of doing soil testing is know about the nutrients of soil so that a farmer can plant the specific crop or can put the correct amount of correct fertilizer or manure

Method

in soil testing we test the following things

  1. OC [organic carbon]
  2. N[nitrogen]
  3. P[phosphorous]
  4. K[potash]
  5. PH

Testing is being done of simple garden soil

How can we test the following

1 OC [Organic Carbon]

Things to be needed

  1. 100 milligram spoon
  2. siring of OC
  3. Dropper
  4. OC1 chemical
  5. OC2 chemical
  6. OC3 chemical
  7. 2test bottle [5 ml]
  8. Funnel

Process

  • Put 100 mg soil in the bottle
  • put OC-1 0.1ml in the bottle
  • then put OC-2 80 drops in the bottle
  • now weight for 30 minutes
  • after 30 minutes
  • put OC-3 up to the 5ml mark
  • now after 5 minutes take the reading by the help of OC reading instrument

after taking the reading the OC in the soil is 0.3

OC = 0.3

2 N [ nitrogen ]

Things to be needed

1 gram spoon
Dropper
AN 1 chemical
AN 2 chemical
AN 3 chemical
2test bottle [5 ml]

Funnel

Process

  • take a bottle
  • then put 1 gm soil in it
  • put 5ml N-1in bottle
  • now let the soil be separated from water for 5 minutes
  • now in a clean bottle put 2ml from 1st bottle in 2nd bottle
  • put 4 drop of AN-2 in it and 4 drop of AN3 in it
  • now mix it genteelly and leave it for 5 minutes
  • after 5 min it is ready to test by available nitrogen color chart

after testing we got to know the nitrogen is very low 140

nitrogen =very low 140

3 P [Phosphorous ]

Things to be needed

  • 1 gram spoon
  • Dropper
  • Funnel
  • AP 1 chemical
  • AP 2 chemical
  • AP 3 chemical
  • 2test bottle [5 ml]

PROCESS

  • take bottle no 1 and put AP-1 up to 6ml mark
  • now put 1 gm soil in bottle through a funnel
  • now wait for 5 minute
  • now fill the solution upto the 3ml mark in 2nd bottle
  • now put 6 drops of AP-2 in it and mix gentely
  • then put 3 drops of AP-3 in the bottle and mix it gentle
  • as the bottle color turns blue we can check Phosphorous

after testing we got to know the phosphorus is 0

phosphorus = 0

\

4 K [potash]

Things to be needed

  • 1 gram spoon
  • Dropper
  • Funnel
  • AK 1 chemical
  • AK 2 tabulate
  • AK 4 chemical
  • 2test bottle [5 ml]

PROCESS

  • take bottle no 1 and put AK-1 up to 6ml mark
  • now put 2 gm soil in bottle through a funnel
  • now wait for 5 minute
  • now fill the solution upto the 2ml mark in 2nd bottle
  • now pot 1 tabulate of AK – 2 in the bottle and mix it gently
  • wait for 5min
  • purple color will come
  • now take AK-4 1 ml in dropper and gently put 2 drops in the bottle until the color changes from pupal to blue

after testing we got to know the potash in soil is high

potash = high [300]

5 PH

Things to be needed

  • reagent ph 1
  • spoon 1gm
  • funnel
  • test bottle

process

  • take ph 1 in bottle no 1 upto 5 ml mark
  • add 2gm soil with funnel
  • put the cap and mix gently
  • wait for 10 minute
  • after 10 min we can check the ph of soil

after testing we got to know the potash in soil is high

ph = 6.5 to 7

so according to the table i should put more manure in field according to the nutrious value for example we can put

cow dunk manure , vermicompost , jeevamrit , bio gas scullery , etc

From this we got to know the problem of nutrient deficiency faced by me after plantation but now i am aware by it and can fix it and the production will not be affected
