- Nitrogen is the most essential nutritional element for sorghum during the intense growth and the formation of generative organs.
- Roots absorb phosphorus from the first days of vegetation and until the plant ejection phase.
- Potassium is absorbed by plants evenly throughout the growing season.
- Large accumulation of green mass and roots occurs if nitrogen is used in conjunction with phosphorus and potassium. Meanwhile, the harvest of the crop increases by 0.8-1.0, and the green mass — by 9.0-10.0 t/ha.
- Microelements, especially molybdenum, cobalt, copper, and iodine, exert a positive effect on harvest. Sorghum absorbs them from the soil more efficiently relative to corn.
