The tests here for organic carbon and pH look like a testing error: almost every test reads the same, unlike the districts around. They aren't used.

Too few tests here to judge nitrogen (1 test).

Fixes are the usual advice. Your Soil Health Card or nearest Krishi Vigyan Kendra gives the exact dose for your field.
