• Nitrogen

  From 3,089 soil tests

  Okay
  Low 30% Medium 69% High 1%

  3 in 10 soil tests here came out low

  If your field is low: add about a quarter more urea than the usual dose, in two or three splits. A pulse crop in rotation also adds nitrogen.

  What this means

  Grows leaves and stems. Short soil gives pale, yellow leaves.

  Low under 280 kg/ha Medium 280–560 kg/ha High over 560 kg/ha

  Healthy soil has 280 kg/ha or more.

  Okay
  Low 26% Medium 12% High 62%

  3 in 10 soil tests here came out low

  If your field is low: add 4 tonnes of compost or farmyard manure per acre before sowing, and plough crop leftovers back in instead of burning them.

  What this means

  Shows how much organic matter the soil has. It keeps soil loose, holds water and feeds the crop slowly.

  Low under 0.5% Medium 0.5–0.75% High over 0.75%

  Healthy soil has 0.5% or more.

  Compared with the wider area

• pH

  From 3,089 soil tests

  Okay
  Acidic 35% Neutral 65%

  3 in 10 soil tests here came out acidic

  If your field is acidic: add agricultural lime before sowing. A soil lab works out how much your field needs.

  What this means

  How sour (acidic) or alkaline the soil is. It decides which nutrients roots can take up.

  Acidic Neutral Alkaline

  In these tests, neutral means about pH 6 to 8, which suits most crops; acidic is below about 6 and alkaline above about 8.

  Compared with the wider area

  Place	Acidic	Neutral	Alkaline

• Salt

  From 3,088 soil tests

  Good
  Not salty 100%

  Almost no soil tests here came out salty

  What this means

  Salt in the soil, shown as EC on the card. Salt makes it hard for roots to drink.

  Not salty Salty

  Under 1 dS/m is fine. Between 1 and 4, only crops that can't take salt lose yield. Above 4 harms most crops.

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

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