Agricultural Lime

Longcliffe supplies an extensive range of agricultural liming materials including ground limestone and dolomite and blended products

Product Overview

Ground Agricultural Limestone

Ground agricultural limestone is a granular calcium carbonate produced from very high purity Carboniferous Limestone suitable for use with all modern spreaders. It is a quick acting liming material with a high neutralising value (NV) and provides essential calcium. Granule size is nominally less than 3.35mm.

The typical physical properties of Longcliffe ground agricultural limestone are as follows:

Appearance grey/off white fine granules
Total neutralising value* 55.0%
Typical Moisture (%) 2
Granule Size nominally <3.35mm

*CaO equivalent on a dry weight basis. For further information please consult the relevant technical data sheet.

Supamag Ground Dolomite

Supamag is a buff/brown, granular dolomite produced from very high purity Carboniferous Dolomite. It is a quick acting liming material with a high neutralising value (NV) and provides essential magnesium. Granule size is nominally less than 3.35mm. It is used as an alternative pH improver for those applications requiring a magnesium supplement

The typical physical properties of Supamag ground agricultural dolomite are as follows:

Appearance buff/brown granules
Total neutralising value* 58.0%
Calcium Oxide (%) 31.5
Magnesium Oxide (%) 19.5
Typical Moisture (%) 2
Granule Size nominally <3.35mm

*CaO equivalent on a dry weight basis. For further information please consult the relevant technical data sheet.

Calcimag Limestone & Dolomite Blends

Calcimag is a blend of granular calcium and calcium-magnesium carbonates produced from very high purity Carboniferous Limestone and Dolomite. It is a quick acting liming material with a high neutralising value and provides essential calcium and magnesium. Granule size is nominally less than 3.35mm

The typical physical properties of Supamag ground agricultural dolomite are as follows:

Appearance grey/buff granules
Total neutralising value* 56.5%
Calcium Oxide (%) 43.5
Magnesium Oxide (%) 10.4
Typical Moisture (%) 2
Granule Size nominally <3.35mm

*CaO equivalent on a dry weight basis. For further information please consult the relevant technical data sheet.

Our operations are fully accredited to ISO 9001 and ISO 14001. Datasheets and SDS on specific grades are available on request. Please contact us for further information.

Packaging

All agricultural liming products are available in bulk.

REACH

Both Limestone (CAS: 1317-65-3 & EINECS: 215-279-6) and Dolomite (CAS: 16389-88-1 & EINECS: 240-440-2) are exempt from the obligation to pre-register under the REACH legislation. The exemption is granted in Annex V, Paragraph 7 as the materials are naturally occurring minerals found in nature.
