• Nitrogen

  From 37,909 soil tests

  Okay
  Low 40% Medium 59% High 1%

  4 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.

• Phosphorus

  From 37,916 soil tests

  Okay
  Low 36% Medium 43% High 21%

  4 in 10 soil tests here came out low

  If your field is low: add about a quarter more DAP or single super phosphate than the usual dose, at sowing.

  What this means

  Builds roots and helps the crop flower and fill grain.

  Low under 10 kg/ha Medium 10–25 kg/ha High over 25 kg/ha

  Healthy soil has 10 kg/ha or more.

• Potassium

  From 37,924 soil tests

• Organic carbon

  From 37,873 soil tests

  Good
  Low 3% Medium 11% High 86%

  Most soil tests here came out high

  What this means

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

  Healthy soil has 0.5% or more.

• pH

  From 37,854 soil tests

  Poor
  Acidic 57% Neutral 43%

  6 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.

• Salt

  From 37,870 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.
