Winter rapeseed is demanding of nutrition, so it is important to supply it with the necessary elements at different plant growth stages.

Proper development, in particular the formation of the stem and root system and resistance to stress conditions, depends on the availability of all necessary macro- and micronutrients.

After feeding with macronutrients on frozen-thawed soil, it will be useful to apply micro-fertilizers to rapeseed after vegetation resumes, when the air temperature reaches +5°C.

The most effective fertilizers for foliar feeding, starting from the resumption of vegetation, will be GROS Phosphito-NP and ECOLINE Boron (Premium)

GROS Phosphito-NP is a unique liquid fertilizer with the highest concentration of phosphorus in phosphite form: 600 g/l.

  • The phosphite form promotes fast entry of phosphorus into the plant and its movement within the plant.
  • Activates root system growth, increases plant resistance to unfavorable weather conditions and to fungal pathogens of the Oomycete class.
  • A high content of nitrogen (300 g/l) in an easily available form strengthens plant growth.
  • Recommended for use in the early growth stages of winter rapeseed at a rate of 1.5–2.0 l/ha.

ECOLINE Boron (Premium) is a liquid fertilizer in the form of an organic complex of boron with monoethanolamine and free L-α-amino acids for use on boron-loving crops. The active ingredients, boron, the amino groups of monoethanolamine and L-α-amino acids, are important for plant tissue formation, including cell wall strength and regulation of calcium metabolism. The fertilizer is effective when plants are under stress due to unfavorable weather conditions.

On winter rapeseed crops it is advisable to apply it at 1.0 l/ha.

GROS Phosphito-NP 1.5–2.0 l/ha + ECOLINE Boron (Premium) 1.0 l/ha combine well in tank mixes and improve the performance of crop protection products. The fertilizers can be added to the tank mix during the first insecticide treatment of the crops.

Feeding winter rapeseed according to the recommended scheme is necessary to optimize nutrition, for fast and efficient build-up of vegetative mass and development of the root system; this will make it possible to achieve a high yield level while preserving product quality.
