How to optimise your soil productivity with lime
The weather conditions last autumn have facilitated the application of ground limestone to both grassland and tillage soils.
Liming Irish soils is very beneficial as our soils tend to be naturally acidic and require regular lime application to maintain their productive capacity.
Maintaining soils at the correct soil pH will increase the release of soil nitrogen (N) and improve the availability of soil phosphorus (P) and potassium (K) following application.
The following are answers to some of the most commonly asked questions in relation to lime and managing soils that have been recently limed.
Q Are there different types of limestone used for making ground limestone?
A Yes, there are two types of ground limestone – Calcium (Ca) and Magnesium (Mg) limestone.
Where soils are low in Mg apply magnesium limestone. There are also a range of granulated limes on the market which are based on either calcium or magnesium limestone depending on the product.
Q How much should I apply?
