From 1,732 soil tests
Low 38% Medium 62%
4 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.

9 in 10 soil tests here came out acidic
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 AlkalineIn these tests, neutral means about pH 6 to 8, which suits most crops; acidic is below about 6 and alkaline above about 8.
