Description
Trucal granular limestone is precision-crushed and screened to create a uniform, fine material that offers excellent coverage and performance when applied. Composed of 99% calcium carbonate, it is ideal for adjusting soil pH to improve nutrient availability and soil structure.
Soil naturally becomes more acidic over time due to factors such as rainfall and the application of fertilisers. As acidity rises, essential nutrients become less accessible to plants, which can impact their growth and vitality. Trucal works to restore balance by naturally neutralising acidity, reducing the presence of free hydrogen ions in the soil. While certain plants, such as potatoes and hydrangeas, thrive in more acidic environments, most edible and ornamental plants perform better in soils with a higher pH. Typically, a pH level of around 6.5 is considered optimal for a wide range of garden plants.
With a neutralising value of 55.6% and a fine particle size, Trucal begins correcting soil acidity more quickly than coarser liming materials, delivering faster and more effective results.

Application Recommendations
Where to use
- Ornamental garden plants: Any plants that are not intend for consumption, including plants grown in private gardens
- Edible crops: Any plants that are intended for consumption
- Amenity vegetation: Any areas of semi natural or ornamental vegetation, including trees
- Managed amenity turf: Areas of frequently mown intensively managed turf, including:
- Fields being used for turf production
- All types of sports turf
- Ornamental turf
When to use
Trucal should ideally be incorporated into the soil up to six months prior to seeding to give time for the neutralisation process to occur. On established turfgrass and borders, Trucal can be applied at any time of the year but is most effective when applied in the autumn.

- Trucal requirement depends on the current and target pH as well as the soil type
- *Individual applications should be limited to:
- 0.50kg/m² for turf and areas where soil incorporation is not possible
- 1.00kg/m² for all other areas
- Apply annually or biannually until the requirement is met
- For larger areas use a broadcast spreader to help to achieve even application of Trucal
- On non-turfed areas or prior to seeding, incorporate Trucal into the top 15-20cm of soil
- On established turf and borders broadcast onto a dry surface
- If no rain is forecast, irrigate with 25mm water to wash the Trucal off the plants and into the soil
