Our Hi-Calcium Agri Lime comes from a high purity calcium quarry in Kilkenny and is ground in a modern limestone powders plant on site.
High Calcium Content
Bennettsbridge Limestone is a high calcium limestone quarry, allowing us to produce agri lime with a 98% Calcium Carbonate content. This high calcium content is essential to restore the soils lime status back to the desired pH for optimum fertility and ensure improved soil structure and drainage.
The effectiveness of agri lime relies on two criteria; how effective it is at neutralising the acidity in the soil and how finely ground it is.
Total Neutralising Value
Our Hi-Calcium Agri Lime has a consistent TNV of 98%, which is measure of how effective a lime is at neutralising the acidity in the soil. All lime sold in Ireland has to have a TNV greater than 90% to conform to the Department of Agriculture specification.
The more finely ground a lime is the more surface area it has and the more available it is to react with the acidity in the soil to neutralise it. We place a large emphasis on lime fineness, consistently manufacturing lime with 33% more powder than the Department of Agriculture specification.
Why Apply Agri Lime?
Increased Grass/Crop Production
Increased grass and grain yields of at least 1.5 t/ha are common when optimum soil pH is achieved. This represents a 7:1 return on investment; €7 in additional grass yield for each €1 invested in lime.
Applying agri lime regularly releases up to 80kgs of N/ha/Year and unlocks phosphorus (P) and potassium (K) from organic soil reserves, reducing the need for applied fertilisers.
Soil Biological Activity
Earthworms and other soil organisms are sensitive to soil acidity. Maintaining a neutral soil pH allows them to thrive and breakdown plant residues, animal manures and release nutrients.
Soil Structure & Drainage
Applying calcium agri lime regularly will help condition the soil, which in turn, will improve soil structure and drainage and allow for better root development and nutrient uptake.
WHAT OUR CUSTOMERS HAVE TO SAY…
“We’re getting better graze outs from Bennettsbridge Limestone’s Hi-Calcium Agri Lime. We are definitely growing more grass and by keeping on top of it and spreading little and often, we are getting better results every year.”
Andrew Leeson, Dairy Farmer, Co. Kilkenny
Bennettsbridge Limestone is as a member of Grolime, Ireland’s only agricultural lime quality assurance scheme. Grolime are committed to promoting the many benefits of ground limestone and continue to work with the Department of Agriculture Food and the Marine and Teagasc as part of its ongoing effortsto increase the knowledge of the benefits of agri lime in Ireland.
On silage ground, it is better to lime immediately after cutting, when cover is low. This avoids uptake of lime which can increase the pH in the silage pit, thereby affecting silage preservation. Apply slurry and UREA c. one week before applying lime on silage ground.
In line with the most recent review of the nitrates derogation, from 2020, a liming programme must be implemented based on your current Nutrient Management Plan (NMP) and associated soil analysis results. This is to ensure an improvement in nutrient use efficiency with a resulting reduction in greenhouse gas (GHG) emissions.
Lime must be applied based on soil test results and invoices will be required if inspected.
Farms that must soil sample for derogation 2021 will need to leave 6 months between liming and sampling.
Typical lime requirements is 2.5 to 5.0 tonnes per ha, every 3-5 years. Soil test regularly to confirm lime requirements. Apply a maximum of 7.5t/ha (3.0t/ac) in a single application. Where more lime is recommended, apply the balance after two years.
Lime can be applied at any time of the year, provided the grass sward is low to avoid excess lime sticking to herbage. Mid-summer and autumn are ideal as soils are dryer and firm and there are increased spreading opportunities after grazing and post silage.
