SOLI TESTING : Ph VALUE

  1. Take reagent PH-1  in test bottle 1 up to the 5ml mark
  2. Add 2 flat spoons of soil 2gm in the test bottle n o 1 with the help of funnel
  3. Put and mix by gentle inversions for 1 min
  4. Insert the color chart in the comparator unit and determine the ph

SOIl  TESTING : PHOSPHURUUS VALUE

  1. Take reagent AP -1  in test bottle 1 up to the 6ml mark
  2. Add 1 flat spoons of soil 1 gm in the test bottle no 1 with the help of funnel
  3. Put and mix by gentle inversions for 1 min and let the bottle stand for 5 mins so that the soil settles
  4. Carefully draw the upper fluid with the help of a dropper up to 3ml level mark
  5. To 3ml liquid in the dropper and transfer the same to the test bottle -2 to make the level up to 3ml
  6. 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
  7. Insert the color chart in the comparator unit and determine the phosphorus value

Soil  TESTING : NITROGEN

  1. Take reagent AN -1 in test bottle 1 up to the 6ml mark
  2. Add 1 flat spoons of soil 1 gm in the test bottle no 1 with the help of funnel
  3. Put and mix by gentle inversions for 1 min
  4. To 3ml liquid in the dropper and transfer the same to the test bottle -2 to make the level up to 2ml
  5. To test bottle no – 2 add 4 drops of reagent AN – 2 and mix gently
  6. In test bottle add 4 drops of reagent AN – 3. put cap on mix gently wait for 5 mins
  7. Insert the available nitrogen color chart in the comparator unit . now the nitrogen color and matched the color of the bottle
  8. After 5min put the  bottle in the nitrogen comparator

Soil  TESTING : POTASSIUM

  1. Take reagent AK -1 in test bottle 1 up to the 6ml mark
  2. Add 2 flat spoons of soil 2gm in the test bottle n o 1 with the help of funnel
  3. Put and mix by gentle inversions for 1 min and let the bottle stand for 5 mins so that the soil settles
  4. Carefully draw the upper fluid with the help of a dropper up to 2ml level mark
  5. 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
  6. We take AK-3 in the bottle take 2 drops in the bottle
  7. 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

  1. Add 1 flat spoons of soil 1 gm in the test bottle no 1 with the help of funnel
  2. Pour the reagent OC-1 1ml in the test bottle 1
  3. Mix 80 drops of reagent OC – 2 and mix it with care as it is abrasive chemical
  4. Add reagent OC-3 to make the 5ml allow bottole to settle for 5min
  5. Insert the OC comparator
