Calmasil

ServingAgriculture since 1968

Calmasil, the largest supplier of agricultural lime in Mpumalanga and its associated brand name was established in 1986.  The name Calmasil created from the major components in our lime, namely Calcium, Magnesium and Silica.

The supply of dolomitic agricultural lime into Mpumalanga, Limpopo, Kwa-Zulu Natal and the Freestate grew from 64 000t per annum in 2 000 to and 230 000t per annum in 2009. The relative high silica content makes this lime ideally suited for the sugar can industry.

Over the years Calmasil also supplied processed lime into the gold mine industry to be used in their water treatment plants.  The excellent neutralizing effect of the lime and the relative low cost compare to pure lime resulted in significant cost saving for the client. By improving the balance of critical nutrients and moderating soil acidity, natural lime fertiliser ensures that your yields will be not only bigger, but will be qualitatively improved as well. Crops will taste better and feed produced from these crops will result in healthier livestock.

Due to the seasonality of the agricultural lime industry Calmasil has invested significantly to ensure that lime is always readily available. The 30 000t dry store capacity as well as the 3 000t/day process facility enables Calmasil to supply high quality agricultural lime reliably.

Calmasil distributes the lime in bulk, 50kg bags as well as 1-ton bags.  We have been supplying directly to more than 500 farmers for 25 years.

Benefits

The following are a few of the benefits you will gain by adding agricultural lime to acidic soils.

1. Lime corrects acidification. Soil acidification is part of South Africa land degradation problem.
2. Supplies Ca for "high calcium" legumes and alfalfa. Calcium is an important constituent of cell wall material, adding  strength and stability to the plant. Calcium deficiency causes stunted growth.
3. Fertiliser efficiency is improved when agricultural lime is added  to acid soils. Liming acid soils will increase the uptake of nitrogen, phosphate, potash, sulphur, calcium, magnesium, boron, copper, zinc and  molybdenum.
4. Agricultural lime improves soil structure and promotes worm  activity. The addition of lime to most soils will improve their friability, thus  reducing crusting and clodding of heavy soils.
5. The composting of organic matter in the soil is significantly  improved, thus contributing to good soil composition and less need for ongoing  tillage.
6. Lime reduces the need for costly and potentially toxic chemical fertilisers and completes an eco-friendly and environmentally sustainable approach. It complies with all requirements for ‘organic’ labeling.
