Franzefoss Minerals and quality raw materials

Franzefoss Minerals is a major producer and supplier of lime and dolomite, and our goal is to be a leader in the field. Lime and dolomite are used in a number of important processes and represent some of society’s most important raw materials. Key application areas include agriculture, industry, building and construction, pH regulation and cleaning/purification. Significant volumes of lime and dolomite are exported to similar markets abroad.

Our production plants are situated in the vicinity of naturally occurring mineral deposits and are distributed throughout the country, from Ballangen in the north to Tromøysundet in the south. Our raw materials are of the highest quality, in particular from Tromsdalen, where the lime content exceeds 98.5 per cent.

This quality makes it highly suitable for a number of purposes, in refined form as either quick lime (calcium oxide) or slaked lime (calcium hydroxide).

Creating added value

Lime as a raw material

Lime is an inexpensive and naturally occurring product that we produce at our own facilities.

Limestone, or calcium carbonate (CaCO3), is a type of rock that is found all over the world. It belongs to a group of rocks called carbonates, which primarily contain minerals with carbonates (CO3-2).

Lime is a collective term for calcium carbonate (CaCO3), calcium hydroxide (Ca(OH)2) and calcium oxide (CaO). Calcium carbonate (CaCO3) is found in natural deposits. To make calcium oxide (CaO), limestone is heated to high temperatures. When water is added, heat is generated and the calcium oxide becomes calcium hydroxide (Ca(OH)2), also known as slaked lime or hydrated lime.

At Franzefoss Minerals, we have our own EN ISO 9001 laboratory for quality control of our products. We have accumulated a huge database of historical measurement data that provides in-depth knowledge and confidence in our products. This contributes to flexibility and rapid follow-up of any customer enquiry locally in Norway. We work closely with the Norwegian Agricultural Advisory Service (Norsk Landbruksrådgivning), and our main focus is to ensure optimal quality
of the products we deliver.

Agricultural lime

Lime creates added value for our customers. It is a natural product that helps provide balance for both plants and animals.
In addition, it is environmentally friendly.

We have been in agriculture since 1919, and today, we are Norway’s largest supplier of liming products. Calcium and magnesium are vital both for plant growth and for animal health. Agricultural lime is important for ensuring correct pH levels in the soil for optimum growth. Lime is also added as a source of calcium in animal feed.
We have a well-developed network of lime spreaders distributed throughout the country to ensure that our products can be spread profitably and efficiently on your fields. The Agri Balance System can be adapted to your individual needs and serves as a system supplier of agricultural lime spreading services.
As Franzefoss Minerals has local production plants here in Norway, we can use the Agri Balance System to safeguard quality, efficiency, logistics and – not least – the environment.

Range of applications for the lime we deliver:

•          Grain and oil crops
•          Meadows and pastures
•          Potatoes
•          Vegetables
•          Gardens and lawns
•          Organic farming
•          Lime spreading
•          Snow melting
•          Feed lime
•          Manure cellars
•          Disinfection
•          Composting

Lime as a pH-regulating substance

One of the ways Franzefoss Minerals exercises its corporate social responsibility is by focusing on environmentally friendly products. Lime is a natural product extracted from limestone. Limestone is formed in two ways: organically and inorganically. The organic method is more common and occurs when shells and corals sink to the bottom of shallow water and are later covered with sand and silt.

Pressure and temperature then result in the formation of limestone. With more than one million daily users, lime in its various forms is one of the most common natural products in Norway. Lime is a naturally occurring chemical that is cheaper to use than other pH-regulating substances. Lime contributes to a safer working environment than other comparable – often chemically manufactured – substances.

Agri Balance System

How it works

Franzefoss Minerals is a system supplier of agricultural lime spreading services. We have about 135 lime spreaders distributed throughout Norway, and we work with a number of contractors that provide spreading services in the different regions. All our spreading contractors accept orders for lime, have the necessary modern equipment and carry out the spreading for you.

Soil samples

Soil samples form the basis for a good fertilisation plan. Everyone who receives a production subsidy must store field soil samples that are no more than eight years old. The analyses of these soil samples are used to draw up a fertiliser plan. When individual farmers make a fertiliser plan, it is common practice to consider lime treatment as well, but there is no public requirement to have a separate liming plan. The plans are thus based on soil samples that may be 5–8 years old. The nutritional content in the soil does not change very quickly, but the pH is what changes fastest in relation to measures taken and natural acidification.

How often should you take soil samples?

Today, it is normal to take soil samples every five to six years. How many soil samples each farmer takes per field within the eight years can vary greatly, as there are only recommendations and no requirements. If you want to make a liming map, you must have a good density of soil samples to find the variations in the field. A soil sample may cover an area of around 0.6 to 1 hectares or an area of ​​around 2 to 10 hectares. The soil variations in the field determine how densely soil samples must be taken.

The analyses are inserted into a GPS

The soil analyses form the basis for making a liming map that shows how much lime is needed in the different parts of the fields. The map of coordinates is loaded into a computer that works together with the tractor’s GPS (or an external GPS) and a lime spreader with GPS to ensure that the lime is spread on the field according to the information provided on the map.

Technical equipment

Different technical systems may be used, but the main principle, regardless of system, is that we use GPS technology to spread the lime properly on the fields. Using GPS makes it possible to drive with exactly equal driving distance between passes. The lime spreader is also calibrated based on the type of lime and volume weight.

Today, only a few farmers lime their fields using a lime map, varying the amount of lime as required. Most farmers still use the same amount of lime on the entire field. Maintenance calibration using modern technology provides increased profitability, and the correct pH results in better utilisation of nutrients and fertiliser – which in turn is good for the environment.

Entire value chain

By the “entire value chain”, we mean that we take responsibility from the moment we extract lime from quarries or mines until you achieve a stable pH value in your fields. Franzefoss Minerals supplies high-quality systems with traceability in all stages. We extract, refine, store, transport and supply our lime spreading contractors with lime. Our systems include storage, production, dosing stations and control systems.
