Various mixtures of lime, limestone and dolomite are used in agriculture and forestry, both for correcting acidity in the soil and for adding nutrients which contain magnesium and calcium.
These nutrients are essential for healthy plant growth and for increasing crop yield. In France and Germany, the Lhoist Group has created separate companies, Aumale Synergies, Agriculture Balthazard & Cotte and Rheinkalk-KDI, to produce and distribute a wide array of fertilising products.
Oxyfertil® is the global Lhoist brand for products and services in fertilisation.
In forestry, dolomite-based products stimulate photosynthesis and, by lowering the degree of acidity in the soil, ensure a better assimilation of nutrients, resulting in a significant increase in forest productivity.
In addition, lime- and limestone-based products are used in animal hygiene (Saniblanc®) and animal foodstock (Faunacal®).
