Poor
Nitrogen
From 40 soil tests
Low 88% Medium 13%
9 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/haHealthy soil has 280 kg/ha or more.

If your field is high: you can use about a quarter less DAP than usual.
What this means
Builds roots and helps the crop flower and fill grain.

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.

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.
