    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.

    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.

    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

    Most crops do best at pH 6.5 to 7.5.
