SOLI TESTING : Ph VALUE
- Take reagent PH-1 in test bottle 1 up to the 5ml mark
- Add 2 flat spoons of soil 2gm in the test bottle n o 1 with the help of funnel
- Put and mix by gentle inversions for 1 min
- Insert the color chart in the comparator unit and determine the ph
SOIl TESTING : PHOSPHURUUS VALUE
- Take reagent AP -1 in test bottle 1 up to the 6ml mark
- Add 1 flat spoons of soil 1 gm in the test bottle no 1 with the help of funnel
- Put and mix by gentle inversions for 1 min and let the bottle stand for 5 mins so that the soil settles
- Carefully draw the upper fluid with the help of a dropper up to 3ml level mark
- To 3ml liquid in the dropper and transfer the same to the test bottle -2 to make the level up to 3ml
- To 3ml mark liquid in bottle no -2 add 6 drops of phosphorus reagent AP – 2 and mix gently by the swirling add 3 drops of AP – 3 put the cap on and mix well color will develop
- Insert the color chart in the comparator unit and determine the phosphorus value
Soil TESTING : NITROGEN
- Take reagent AN -1 in test bottle 1 up to the 6ml mark
- Add 1 flat spoons of soil 1 gm in the test bottle no 1 with the help of funnel
- Put and mix by gentle inversions for 1 min
- To 3ml liquid in the dropper and transfer the same to the test bottle -2 to make the level up to 2ml
- To test bottle no – 2 add 4 drops of reagent AN – 2 and mix gently
- In test bottle add 4 drops of reagent AN – 3. put cap on mix gently wait for 5 mins
- Insert the available nitrogen color chart in the comparator unit . now the nitrogen color and matched the color of the bottle
- After 5min put the bottle in the nitrogen comparator
Soil TESTING : POTASSIUM
- Take reagent AK -1 in test bottle 1 up to the 6ml mark
- Add 2 flat spoons of soil 2gm in the test bottle n o 1 with the help of funnel
- Put and mix by gentle inversions for 1 min and let the bottle stand for 5 mins so that the soil settles
- Carefully draw the upper fluid with the help of a dropper up to 2ml level mark
- To te 2ml liquid o=in the bottle no-2 add one tablet of potassium reagent AK – 2 swirling intermediately to assist dissolution ( it may take 5 – 6 mins for complete dissolution the color will change to purple we will commence the testing once the tablet gets dissolved
- We take AK-3 in the bottle take 2 drops in the bottle
- Take reagent AK – 4 in the syringe and add reagent till the color of the solution turns to blue and count the drops while doing it
Soil TESTING : OC
- Add 1 flat spoons of soil 1 gm in the test bottle no 1 with the help of funnel
- Pour the reagent OC-1 1ml in the test bottle 1
- Mix 80 drops of reagent OC – 2 and mix it with care as it is abrasive chemical
- Add reagent OC-3 to make the 5ml allow bottole to settle for 5min
- Insert the OC comparator
