Boric fertilizers bring along with under preseeding processing of the soil. Even subacidic soils izvestkut during the autumn or winter period. Organic fertilizers bring under the previous culture.
If silosut a colza during blossoming when contains in plants to 85 percent of moisture, it is better to add the crushed straw or a polova to silosuyemy weight. Also joint siloing of green material of a colza with corn in the ratio 1 is useful: In such silo 105 — 110 grams of a protein while the from its corn contains only 65 — 75 grams are the share of one fodder unit.
In the early spring at approach of physical ripeness of the soil we carry out a disking or cultivation with a simultaneous boronovaniye, we introduce fertilizers, herbicides, then we start preparation of a field for sowing. The colza — melkosemyanny culture, seeds is closed up to the soil on depth of 1,5 — 2,5 centimeters therefore the soil has to be without excess dispersion, melkokomkovaty, a surface of a field leveled.
