English

Oilseed rape is a member of the brassicaceae (crucifer) family, and an oleaginous plant that prefers fairly cool growing conditions. It is a deep-rooted plant with a pivoting root system. It facilitates lighter crop rotations, takes up available nitrogen in the autumn and provides good soil cover during the winter.

Our solutions

The minimum replanting lead time for a brassica in a rotation system is 5 years.

Oilseed rape does well following autumn barley, spring barley and potatoes. Oilseed rape does not do so well following cabbages, catch crops and green manure crops that include cruciferous vegetables.

Oilseed rape is well suited to cereal-rich rotation systems and livestock farms. Planting oilseed rape at the beginning of the rotation cycle allows meadow grasses, alfalfa, etc.

To benefit from the nitrogen remaining in the soil. The crop must be encouraged to get into leaf quickly during the spring by applying slow-release mineral farm fertilisers at the time of planting.

Nutrient elements absorbed by oilseed rape

Oilseed rape is a nutrient-hungry crop, particularly in terms of nitrogen. Oilseed rape absorbs 2/3 of its total nutrient needs in the spring.

It is a relatively hungry plant in terms of phosphorus. Phosphorus deficiency causes the oldest leaves to turn purple may delay ripening.

Its healthy development is also conditioned by 3 essential secondary elements: sulphur, boron and molybdenum.


18 : internode formation
31-32 : visibly extended
53 : emergence of inflorescences and ramifications
60 : flower buds raised above the youngest leaves
70 : pod and seed formation
80 : ripening


Our organic agriculture solutions

Period of application :
Before planting

Objective: to extract maximum nutritional value from organic inputs and soil organic matter for greater productivity, since oilseed rape is very nitrogen-hungry

  • To maximise the benefits of your soil, the preceding rotation crops and your organic inputs
  • To improve the availability of nutrient elements for more growth and greater yield

Our inputs will also provide calcium, as well as sulphur, to boost crop nutrition, etc.

+

Period of application:
At the time of planting

Objective: to ensure vigorous growth after planting and the stress resistance required to cope with winter

  • Through successful planting to provide longer row cultivation: out-competing weeds
  • By stimulating root growth for wider root spread and higher yields
  • By boosting stress tolerance for higher yields (quality)

Our inputs will also provide potassium, as well as the phosphorus needed to get the plants off to a sound start and ensure good root and leaf development, etc.

Période d’application :
At the time of planting

Objectif : to stimulate crop growth to achieve higher quality by

  • Stimulating root growth
  • Increasing soil fertility by providing organic elements (N-P-K)
  • Improving nutrient absorption

Our inputs will also provide – for example – the potassium required for good nutrition, etc.
