Nutrient by nutrient

  • Nitrogen

    Okay

    Low 25% Medium 75%

    3 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.
