The tests here for manganese 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), out of 902 soil samples.

Not tested here: organic carbon, pH, salt and boron.

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