Why lime is one of best investments

Some 70% of fields on drystock farms are now below the target soil pH of 6.3. 

This means that some of the nitrogen (N), phosphorus (P) and potassium (K) present in these soils, or applied on them in fertiliser and slurry, is significantly less available for the grass to take up.

When the soil pH is at the correct level, the soil releases up to 80kg of N per ha per year, worth €80 per ha per year.
