    Poor

    Low 53% Medium 20% High 27%

    5 in 10 soil tests here came out low

    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.

    Low under 0.5% Medium 0.5–0.75% High over 0.75%

    Healthy soil has 0.5% or more.

  • pH

    From 202 soil tests

    Poor

    Acidic 55% Neutral 45%

    5 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 Alkaline

    In these tests, neutral means about pH 6 to 8, which suits most crops; acidic is below about 6 and alkaline above about 8.

    Almost no soil tests here came out salty

    What this means

    Salt in the soil, shown as EC on the card. Salt makes it hard for roots to drink.

    Not salty Salty

    Under 1 dS/m is fine. Between 1 and 4, only crops that can't take salt lose yield. Above 4 harms most crops.
