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.

Salt in the soil, shown as EC on the card. Salt makes it hard for roots to drink.
Not salty SaltyUnder 1 dS/m is fine. Between 1 and 4, only crops that can't take salt lose yield. Above 4 harms most crops.
