Nutrient by nutrient

  • Nitrogen

    From 123 soil tests

    Poor

    Low 52% Medium 15% High 33%

    5 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.

    Low 40% Medium 31% High 29%

    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

    6 in 10 soil tests here came out low

    If your field is low: add about a quarter more potash (MOP) than the usual dose.

    What this means

    Fills grain and fruit, and helps crops stand drought and disease.

  • Organic carbon

    From 123 soil tests

    Okay

    Low 41% Medium 7% High 51%

    4 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.

  • pH

    From 123 soil tests

    Poor

    Acidic 59% Neutral 41%

    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.
