Winter wheat is a separate wheat variety that is planted in autumn for the development of young plants that remain in vegetative form in winter and resume growth in early spring.

Winter wheat is a separate wheat variety that is planted in autumn for the development of young plants that remain in vegetative form in winter and resume growth in early spring. In our country, winter crops are leading in terms of sown area, even in spite of unsuccessful seasons. Stability is ensured through cultivation technology and proper feeding. This stage is especially important if you need to harvest a good harvest. Recently, mineral fertilizers are increasingly used in agriculture.
Their volumes and rates depend on a number of parameters:

  • type of soil;
  • the main substance in the composition of the fertilizer;
  • feeding time.

Since winter crops are sown at the very beginning of autumn, it is important to provide a comfortable wintering for this crop. In order for wheat to overwinter and give a good harvest, it must be fertilized with enough phosphorus and potassium. This will maximize the development of the shoots. Fertilizers are applied in full during the main soil cultivation. One of the main elements is nitrogen, but in the fall it must be applied at a rate of no more than 30% of the norm.
Fertilizer volumes:

  • no more than 80 kilograms per hectare for regions with sod-podzolic soil;
  • no more than 60 kg per hectare for black soil.

For southern regions, where winters are relatively mild and short, the amount of nitrogen as fertilizer may be different. In this case, the loss of matter during wintering will be minimal. In these areas, nitrogen can be applied in full before sowing winter wheat.

As for the spring feeding, we are talking about the introduction of nitrogen bales. This is an important point, since the growing season begins early in winter crops. Experienced farmers advise to apply at least ½ of the rate when wheat growth is restored and about 1/5 when the ears are blooming and the grains are poured.

In addition to nitrogen, phosphorus and potassium, wheat requires feeding with magnesium, sulfur and calcium. Magnesium provides high-quality protein and carbohydrate metabolism. Also, thanks to this element, faster growth and protection against various diseases occurs. Magnesium fertilizers are applied directly to the soil or used as additional foliar dressing.
As for sulfur, it ensures high-quality protein metabolism and plays an important role in the synthesis of vitamins. Thanks to this element, the development of winter crops is significantly accelerated, and the quality of the crop improves in general. Sulfur in large amounts contains:

  • in ammonium sulfate - experts recommend this fertilizer for acidic soil;
  • magnesium sulfate - the optimal solution for foliar feeding;
  • potassium magnesium sulfate - a universal option for simultaneous fertilization with important substances;
  • other various sulfates (used much less frequently).

Calcium provides reliable protection against disease and promotes quality photosynthesis. This element also improves the root system. Lime is used to enrich the soil, but this is only relevant for growing winter crops on acidic soil. Wheat in general requires feeding not only with important macronutrients, such as nitrogen, phosphorus and potassium, but also with other, no less important ones. Tuki should be used in normalized volumes and must necessarily correspond to the type of soil.
