The objectives of a so-called “permanent” natural grassland differ from the objectives of a temporary grassland. This is why it is advisable to adapt cultural principles based on the specificities of particular meadows.

Maintaining good meadow quality in the medium and long term is synonymous with dry matter yield and nutritional value. This maintenance is based on two fundamental pillars known by breeders: management of organic matter and soil pH.


To promote the development of legumes, a sign of high-quality grass growing, it is necessary to fight against the natural acidity of the soil. There are several reasons for this:

  • Certain species or varieties within prairies have a high demand for calcium
  • Legume nodules that facilitate nitrogen management in the plot develop best in soil with pH> 6
  • The closer the pH is to neutral, the easier is the management of organic matter on the farm.

By maintaining a good pH in the soil, the balance between microorganisms is adapted to facilitate mineralization and humidification of organic matter. This generates tons of dry matter per hectare and good fodder values within prairies.

For better grass production in your meadows

Thanks to the bio activators present in the Calkorium and Calkonutrium prebiotic premixes, microorganisms multiply quickly and naturally in the soil. This multiplication allows good degradation of organic matter, both in fertilizing units usable by grassland species and in humus thus stimulating soil fertility.

By effectively combating the acidity of soils in meadows, the solutions proposed by FCA Fertilisants benefit all plant species while increasing the richness and diversity of the cultivation of grass. The proposed fertilization solutions promote the yield of the grass crop, increasing both quantitatively and in terms of fodder values.
