Sugarbeet develops properly on fertile soils with a pH in the range of 6.2 - 7.2. The long period of beet vegetation determines the possibility of effective use of organic fertilizers by the plant. What is more, sugarbeet is highly sensitive to soil salinity, and its quick start and optimal emergence are conditioned by constantly providing the plant with the best possible development conditions. It is the fertilization that mainly determines the yield, sugar content, development rate and general quality of sugarbeets.
Mineral fertilizers are the basis for efficient sugarbeet yielding. They should be carefully selected according to the soil conditions and the actual nutritional needs. It is precisely: nitrogen, potassium, phosphorus, sodium, sulfur, boron, manganese, zinc and magnesium that determine the dynamics of plant growth and its yield. These ingredients can be supplied to the plant in the form of foliar fertilization. It is extremely important that they are delivered in accordance with the beet fertilization schedule.

It is extremely important that they are delivered in accordance with the beet fertilization schedule.
Nitrogen fertilization stimulates the development of the beet's leaf surface, which enables photosynthesis and the production of carbohydrates that accumulate in the plant's root. The first dose of nitrogen should be delivered before sowing before the cultivator or in the early stages of beet growth. It is worth ensuring that the nitrogen dose is in the range of 50 to 70 kg per hectare.
The next dose of nitrogen should be applied for top dressing and it falls on the beet development stage from the 4th - 5th leaf formation to the beginning of the inter-row covering.
Phosphorus is one of the ingredients that regulates the yield of roots and increases the sugar content in them. Additionally, it stimulates the development of the plant's root. Phosphorus fertilization should be carried out mainly in the sugarbeet emergence phase.
Potassium is one of the most important nutrients for sugarbeets. Its task is to regulate the carbohydrate and nitrogen balance, which affects the amount of sugar in the root. Potassium fertilizers regulate the plant's resistance to water stress and ensure its proper development.
Magnesium regulates the nitrogen balance of sugarbeets, and also helps to maintain the optimal amount and quality of sugar in the roots. Fertilization with magnesium sulphate should be carried out throughout the development period of the sugarbeet.
Boron is one of the key elements, the deficiency of which inhibits plant growth and affects wilt, diminution and cracking of the leaves. Large boron deficiencies can reduce the sugarbeet yield by up to 50%, and the sugar content itself by up to 4%. Foliar fertilization with boron should be performed three times during the growing season at a dose of not less than 100 g per hectare. The first dose should be applied in the 4 leaf phase, while the second dose should be applied before the inter-rows covering.
The appropriate sodium content affects the proper growth of the plant and its roots, and also hydrates the beets. Iron participates indirectly in protein synthesis, and manganese regulates the nitrogen balance of the plant, intensifying photosynthesis. Sugarbeet should be supplemented with small doses of these elements at least 2-3 times in the period from leaf development, during leaf rosette growth and root development.
The demand of sugarbeet plants for the above-mentioned microelements is covered by the most concentrated foliar fertilizers, the elemental composition of which (nutrient content) has been composed in accordance with the nutritional requirements of the beet at individual stages of its growth and development.
