• Nitrogen

  Poor
  Low 94% Medium 6%

  9 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.

• pH

  Okay
  Acidic 47% Neutral 53%

  5 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
  Here	47%	53%	0%
  Mizoram	53%	47%	0%
  India	12%	86%	2%

Too few tests here to judge salt (3 tests), sulphur (2 tests), zinc (1 test), iron (1 test), copper (1 test), manganese (1 test) and boron (1 test).

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