Peculiarities of feeding sugar beets
To form 1 ton of root crops, sugar beets absorb 5-6 kg of nitrogen, 2-2.5 kg of phosphorus and 6-7 kg of potassium from the soil. Thus, to provide the crop yield of 50 tons per ha and the relevant quantity of tops, the sugar beet plants need: 250-300 kg of nitrogen, 100-125 kg of phosphorus and 300-350 kg of potassium. The necessity of such nutrients as calcium, magnesium and sulphur in their proportion is lower than of the abovementioned major elements, but is still considerable. Boron and mangan are vital for the culture. Mangan activates the oxidation processes or the restoration of nitrogen compounds and the accumulation of sugar in the root crops.
Boron compounds facilitate synthesis of sugar, provide their flow from the leaves to the root crops, thus increasing the content of saccharose in the root crops and the process yield of sugar at the sugar mills.
