Preparing rapeseed for successful overwintering
Let's prepare the rapeseed for a successful winter!
Low temperatures and lack of precipitation - this is what November brought to the fields in most of the country. For another year, nature has put farmers who decided to grow rapeseed to the test.
Only a part of the rapeseed crops, mainly those sown in early autumn, have a rosette formation phase (5-6 leaves) - a suitable phase for wintering. Cold and drought lead to the retention of vegetation processes in plants.
In these stressful conditions, the best thing you can do for your crops is to nourish them with a complex of macroelements, microelements and amino acids, which will accelerate vegetation and help the plants successfully winter. But the intake of microelements through the soil is an energy-intensive process that further exhausts delicate plants. When applied foliarly, the nutrients are quickly absorbed through the leaves and improve rooting.
Our offer is CODAFOL MAXIMUS - a liquid NPK foliar fertilizer that is quickly absorbed and has an invigorating, anti-stress effect. The amino acids and natural stimulants contained in Codafol Maximus activate the immune system of plants and give them the strength to fight stress factors.
In addition, Codafol Maximus contains a complex of microelements, key to the development of rapeseed and usually deficient in saline soils with high pH and high sodium content - Zinc (Zn), Manganese (Mn), Boron (B), Magnesium (Mn).
WHY ARE THESE MICROELEMENTS IMPORTANT?
Zinc (Zn)
It is a component of over 80 enzyme systems. Important for the development of roots and for the optimal vegetation of rapeseed. Zinc has a direct or indirect effect on photosynthesis, respiration, biosynthesis of chlorophyll and growth regulators, phosphorus, nitrogen and carbohydrate metabolism. Zinc-fertilized rapeseed takes root better and overwinters more successfully. Zinc deficiency is aggravated by high pH, soils with high organic matter content, rich in phosphorus, high phosphorus fertilization, humid and cold conditions.
Boron (B)
The needs of rapeseed for boron are much greater than those of cereals. Boron increases the yield of grain and oil, is necessary for the growth and yield of rapeseed and oil. It is important for the general development of the crop, reducing plant losses from overwintering, improves the accumulation of reserves in rapeseed for better and faster spring development, improves flowering and makes ripening uniform. It plays an important role in the construction, functions and strength of the cell wall, cell division, seed formation, sugar transport, pollen germination and pollination, absorption and transport of calcium in the plant, hormone synthesis.
Hollow stems and roots are symptoms of boron deficiency that are difficult to detect but can be fatal to the plant.
Manganese is one of the most important nutrients for rapeseed. It improves overall development, reduces plant losses during wintering, helps build up reserves in plants, and they improve early spring development of the crop. Manganese improves flowering and uniform ripening. It is necessary for photosynthesis, respiration and nitrogen absorption. It is important for pollen germination and pollination, root elongation and resistance to soil enemies and pathogens. Manganese is involved in the synthesis and functions of vitamins in the plant.
The initial symptoms of manganese deficiency can be found on the leaves - spotted chlorosis is observed.
Magnesium (Mg)
A very important element for the successful development and overwintering of rapeseed. Reduces plant losses from overwintering, improves the accumulation of reserves in the plant, which leads to rapid and accelerated spring growth. Improves flowering and leads to even ripening of the pods. Increases seed yield and oil content in the seeds. Participates in the synthesis of carbohydrates, fats and proteins. Important for the synthesis of amino acids and cellular proteins. Increases the resistance of plants to drought.
With a magnesium deficiency, plants slow down their growth, flowering and pod setting are weak, and a manifestation on the leaves can be observed in the form of a pale yellow color.
Young plants nourished with the right microelements are better rooted, healthier, with thicker leaves with an increased sugar content in them. This leads to improved winter and cold resistance of rapeseed and creates a prerequisite for its successful overwintering.
Our other proposal for targeted nutrition with key microelements in the rosette phase of rapeseed is the combination of Codamin B-Mo and Magne Raps S at a dose of 150 ml/ha.
Codamin B-Mo is a liquid foliar fertilizer with boron and molybdenum, enriched with amino acids of plant origin. In addition to correcting boron and molybdenum deficiencies in plants, it supports protein synthesis, transport and their absorption by cells, stores plant energy, and stimulates their resistance to adverse conditions.
Magne Raps S is a liquid foliar fertilizer that provides short-term and long-term nutrition with magnesium and sulfur. It is produced with proprietary surfactant blends that provide improved rain resistance and superior tank mix compatibility. The fine particles provide better leaf coverage and a larger absorption surface area, leading to rapid and complete absorption of the product.
When do rapeseed plants suffer from sulfur deficiency?
Most often in acidic, light, sandy soils with low organic matter content, waterlogged and compacted soils with poor aeration. You will notice signs even in young plants - their leaves turn yellow, with purple hues, their growth slows down. Subsequently, they curl upwards. In spring, impaired flowering and pod setting are observed, which inevitably affects the yield.
Consult our agronomists about the most appropriate scheme for feeding your rapeseed crops, depending on their condition, soil type, moisture availability and agrometeorological features in your region.
