  Poor
  Low 57% Medium 43%

  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.

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

  Healthy soil has 0.5% or more.

  Good
  Neutral 99% Alkaline 1%

  Almost every soil test here came out neutral

  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.

  From 15,726 soil tests

  Poor

  5 in 10 soil tests here came out salty

  If your field is salty: grow crops that take salt, level the field, and wash the salt down with good water before sowing.

  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.

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