Sorghum
Sorghum – is bread, technical and feed crop. Grain contains 61-68% of starch, protein 7,8-16,7%, 1,7-6,5% fat, characterized by high cellulose content. It is used to produce flour, cereals, alcohol, starch, and more. From sorghum stems (contains 18% sugar) can be obtained molasses (sorghum honey). Grain and green mass is used to feed cattle. Straw is used as raw material for paper, cardboard, wicker products, brooms; it covered roofs, used for fuel. With dry stems of some species red dye for leather can be obtained. Sorghum differs by its ease adaptation to different soil and climatic conditions, heat-loving, drought-resistant, tolerates high concentration of salts in the soil. In Ukraine there are 5 types of sorghum, 4 of them are cultivated mainly in the southern parts of the country (steppe, but can also be grown under steppes and is one of the most promising grain-feed crops in this area). Sorghum bears repeated planting and can be grown in a permanent place. Demand of sorghum to the fertilizers, as the corn, is quite big. It positively reacts on putting complete mineral fertilizer at the rate kg / ha: N45-60P45-60K45-60. On the black soil Sorghum is more sensitive to phosphorus fertilizers, on chestnut soils - nitrogen-phosphorus. Higher doses of nitrogen fertilizers contribute to the accumulation in the green mass of the sorghum toxic cyanide compounds that must be considered when growing sorghum for green fodder.

Microfertilizers «UAROSTOK»® is non-toxic to humans and bees do not cause allergies and environmentally safe.
Sorghum is the most sensitive to microelements: manganese, zinc, iron, molybdenum; this crops is less sensitive to the security of cooper, weakly reacts on – boron and sulfur.
