Soil amendments and improvers

Calcium Carbonate (CaCO3) is a component of many products developed by the agribusiness sector, including fertilizers and soil improvers.

CaCO3 : a healthy product which helps improve soil fertility and ensure a correct balance of minerals.

Our limestone fillers are ground to different particle sizes to be used at every stage of the crop production process – amending the soil by correcting soil acidity and improving soil structure and adding calcium to boost soil nutrient levels. These mineral additives in powder form are used in many agribusiness products.

The quality and chemical purity of our mineral raw material products make them the preferred choice for agricultural sector actors pursuing a sustainable, integrated approach.

Extracted, crushed and ground by our partner, les Carrières de la Vallée Heureuse in Rinxent in the département of the Pas-de-Calais, this mineral product is 100% French-made and destined for the agribusiness sector.
