FACTORS OF FERTILITY-IMPROVING SOIL FOR STUDY ELEMENTS OF TECHNOLOGY GROWING SOY

Abstract.

It was found that the optimum seeding rate of early maturing varieties of soybean on light – gray soils, is: – 800 thousand units / ha, which ensures the formation of optimum leaf area, photosynthetic potential and net photosynthetic productivity. Due to the intensive development nitrogen-fixing bacteria in the soil accumulates 118 kg. biological nitrogen, which is equivalent to 347 kg of ammonium nitrate value of 3296 UAH / ha. 

Keywords: varieties, timing, seeding rate, soil temperature, yield, biological nitrogen
