METHOD OF SOY CULTIVATION Russian patent published in 2009 - IPC A01B79/02 

FIELD: agriculture.

SUBSTANCE: method of soy cultivation includes application of microelements during particular phase of growing together with macro fertilisers of nitrogen, phosphor and potassium. Microelements are dosed into root systems together with irrigation water by drop irrigation system. Microelements are applied in the form of a solution of bischofite natural mineral of the formula MgCl₂·6H₂O in phase of plants' vegetation. For ultra early varieties with heat availability1700°C and less at the ratio of 6-10 wt % of bischofite water-salt solution 1.2-1.3 t/m³, l/hectare: Seeding and sprouting 25-50; Budding 30-60; Blooming 20-40; Fruit inception 60-80; Ripening 70-120. For very early repining soy varieties with thermal availability 1701-1900°C, the solution of bischofite is prepared at the rate of 10-15 wt % of water-salt solution of bischofite with a density 1.2-1.3 t/m³ and applied by norms of l/hectare in the phase: Seeding and sprouting 30-55; Budding 35-70; Blooming 25-50; Fruit inception 40-60; Ripening 60-100. For early repining varieties of soy with thermal availability 1901-2200°C, the solution of bischofite is prepared at the rate of 12-18 wt % of water-salt solution of bischofite with a density 1.2-1.3 t/m³ and applied by norms of l/hectare in the phase: Seeding and sprouting 25-50; Budding 30-60; Blooming 20-45; Fruit inception 35-55; Ripening 45-85. For intermediate repining soy varieties with thermal availability 2201-2300°C, the solution of bischofite is prepared at the rate of 10-15 wt % of water-salt solution of bischofite with a density 1.2-1.3 t/m³ and applied by norms of l/hectare in the phase: Seeding and sprouting 20-45; Budding 25-55; Blooming 20-60; Fruit inception 40-60; Ripening 40-80. For intermediate varieties of soy with thermal availability 2301-2400°C, the solution of bischofite is prepared at the rate of 18-25 wt % of water-salt solution of bischofite with a density 1.2-1.3 t/m³ and applied by norms of l/hectare in the phase: Seeding and sprouting 30-50; Budding 30-60; Blooming 30-90; Fruit inception 50-70; Ripening 60-90. For intermediate late ripening soy varieties with thermal availability 2401-2600°C, the solution of bischofite is prepared at the rate of 20-30 wt % of water-salt solution of bischofite with a density 1.2-1.3 t/m³ and applied by norms of l/hectare in the phase: Seeding and sprouting 30-35; Budding 30-40; Blooming 30-45; Fruit inception 50-55; Ripening 60-65. For late repining soy varieties with thermal availability 2601-3000°C, the solution of bischofite is prepared at the rate of 25-35 wt % of water-salt solution of bischofite with a density 1.2-1.3 t/m³ and applied by norms of l/hectare in the phase: Seeding and sprouting 35-40; Budding 35-60; Blooming 35-45; Fruit inception 55-60; Ripening 65-70. For very late repining soy varieties with thermal availability 3001-3500°C, the solution of bischofite is prepared at the rate of 30-40 wt % of water-salt solution of bischofite with a density 1.2-1.3 t/m³ and applied by norms of l/hectare in the phase: Seeding and sprouting 40-45; Budding 40-50; Blooming 40-65; Fruit inception 60-70; Ripening 70-75. For especially late ripening varieties of soy with thermal availability more than 3500°C, the solution of bischofite is prepared at the rate of 35-45 wt % of water-salt solution of bischofite with a density 1.2-1.3 t/m³ and applied by norms of l/hectare in the phase: Seeding and sprouting 45-50; Budding 40-45; Blooming 35-40; Fruit inception 50-60; Ripening 75-80.

EFFECT: increase of protein and fat content and decrease of trypsin inhibitor activity.
