Nitrogen
From 33 soil tests
Low 45% Medium 52% High 3%

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/haHealthy soil has 280 kg/ha or more.

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.
