Nutrient by nutrient

  • Nitrogen

    Okay

    Low 24% Medium 65% High 12%

    2 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.

    Okay

    Low 35% Medium 47% High 18%

    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.
