Céréales à paille


Straw cereals are cultivated in France on more than 7 million hectares, that is to say more than 1 out of 6 hectares of the total French agricultural surface. This type of production includes many varieties depending on the species: common wheat, durum wheat, winter barley, spring barley, triticale, oats and others.

If autumn is characterized by the germination of seeds and the growth of seedlings, it is in spring that the foliage develops and the stems (tillers) multiply and elongate. The grains are formed and filled at the end of the cycle. Outside of winter, the plant will feed throughout its cycle.

Producing straw cereals, such as common wheat for example, has two objectives:

  • Continue and feed grain production
  • Increase the protein content of these grains


To meet these 2 parallel objectives, the reasoning for fertilization includes 3 criteria:
  • The total dose
  • The fractionation
  • The form of the fertilizer
The total dose corresponds to the difference between the needs of the plant and the soil supplies. These supplies include:
  • The remainder of winter output
  • The aftereffects of effluents
  • Mineralization of previous crop residues and soil organic matter
The mineralization stage is fundamental to make bio-available mineral elements naturally present in the soil for plants. Mineralization is a guarantee of the effectiveness of good nutrition throughout the crop cycle until harvest, which ensures a yield in quantity with well-filled grains.

For better production of straw cereals

True stimulators of biological activity and the mineralization of organic matter, the Calkorium and Calkonutrium fertilization ranges allow the real coefficient of use of fertilizers to be increased.

Formulated to allow the development of bacteria and fungi capable of mineralizing and humidifying, prebiotic premixes with Calkorium and Calkonutrium maximize yields both quantitatively and qualitatively for farmers. They thus allow the transformation of organic matter into bioavailable fertilizing elements and into humus, nourishing support for cereal straw crops.
