This shows what soil in this area tends to be like. Your own field can be different. Get it tested at a soil testing lab before deciding.

Nutrient by nutrient

  • Nitrogen

    Poor

    Low 100%

    Almost every soil test 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.

    6 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.

  • Organic carbon

    Poor

    Low 100%

    Almost every soil test 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.

    Okay

    Acidic 3% Neutral 61% Alkaline 36%

    4 in 10 soil tests here came out alkaline

    If your field is alkaline: add compost or farmyard manure. Very alkaline land also needs gypsum; a soil lab works out how much.

    What this means

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

    Acidic Neutral Alkaline

    Most crops do best at pH 6.5 to 7.5.
