In spring, as warmth arrives, winter rapeseed actively forms vegetative mass and, along with it, the generative organs responsible for forming the future seed yield of high quality.

One of the critical stages is the start of stem elongation. In this period plants need increased supply of the main macro- and microelements. While plants are usually supplied with the main macroelements nitrogen, phosphorus and potassium, since thanks to applied fertilizers and sufficient soil warming all these elements are available to plant roots, with magnesium, sulfur and boron a critical situation develops in many cases, often without visual signs of shortage of one or another nutrient. Such shortage can be established only from functional diagnostics results. To eliminate the identified plant need for mineral nutrients, ECOORGANIC LLC recommends using a number of special fertilizers in rapeseed feeding systems: Ecoline Magnesium (Chelates), Ecoline Boron (Premium) and Ecoline Boron (Organic). If signs of stress appear on plants, we recommend foliar feeding with the anti-stress products Ecoline Phosphite (K-Amino) or Ecoline Universal Growth (Amino), which have an immunostimulating and anti-stress effect on plants.

Foliar feedings with these compositions, both on trial plots and on commercial crops in all natural and climatic zones of our country, showed high effectiveness, accompanied by elimination of deficiency of individual mineral nutrients and powerful plant growth.

Ecoline Phosphite (K-Amino) supplies plants with phosphorus in the form of phosphite and promotes balanced nutrition with nitrogen and potassium. Phosphorus strengthens root system growth and stimulates the production of phytoalexins in plants (raising immunity). Phosphite has a weak fungicidal action, owing to which it can restrain infection by pathogens and the development of fungal diseases. Potassium contained in the microfertilizer helps maintain plant turgor, ensuring metabolic processes. L-α amino acids improve the plants' energy balance and help them overcome stress faster.

Magnesium is extremely important in plant metabolism. It promotes root system growth and transport of nutrients to plant organs. Magnesium is indispensable in photosynthesis, activation of most enzymes and energy conversion. The microfertilizer Ecoline Magnesium (Chelates) contains magnesium in chelate form and chelated forms of metal microelements that activate chlorophyll function.

With boron deficiency, which shows on young plant parts (small, deformed, corrugated and brittle leaves with chlorotic spotting and violet colouring of the edges), we recommend the special fertilizer Ecoline Boron (Premium), which not only eliminates boron shortage but also relieves signs of stress thanks to the L-α amino acids it contains.

Thus, to preserve the yield potential of winter rapeseed under the existing conditions, we recommend foliar feeding based on the actual condition of plants in a particular field:

  1. On poorly developed, heavily suppressed crops apply Ecoline Boron (Organic) 1.0 l/ha + Ecoline Phosphite (K-Amino) 1.0 l/ha
  2. With magnesium deficiency: Ecoline Phosphite (K) 1.0 l/ha + Ecoline Magnesium (Chelates) 1.0 l/ha.
  3. On normally developed crops: Ecoline Boron (Premium) 1.0 l/ha.
