A field test for calcareous soil involves observing effervescence (bubbling) when a soil sample is treated with a dilute acid, typically hydrochloric acid or vinegar. This reaction indicates the presence of calcium carbonate (CaCO3), a key component of calcareous soils. Calcareous soils also tend to have a pH above 7 and may exhibit a lighter color due to the presence of CaCO3
Any Acid, for crude method Use Lemon Juice
Took the Soil pad from the profile and squeezed lemon by hand or already collected lemon juice with the help of droper
| Layer | Depth Cm | Intensity of bubbling | Result |
|---|---|---|---|
| A | 0-5 | Low | Low |
| B | 5-10 | Mild | High |
| C | 10-50 | Very Vigorous | Extremely High |
| R |
Generally Calcariousness is high with the depth
all the layers do not have same ammount of calcariousness in soil
it very with the depth
