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.

  • Nitrogen

    Good

    Low 14% Medium 85% High 1%

    1 in 10 soil tests here came out low

    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.

  • Phosphorus

    Okay

    Low 24% Medium 66% High 11%

    2 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
