The inspections of winter rapeseed oil crops carried out last week indicate that crops with intensive vigor, in the 8-12 leaf phase, show boron deficiencies. Mid-October is the last moment to supplement the lack of this important nutrient by foliar application. Foliar application can be performed while maintaining a minimum temperature of +5 C and without the possibility of ground frosts. In this last foliar application, a fertilizer containing manganese can also be used. We propose using our new innovative fertilizer complexed with a 100% organic factor.

VitaFer®B  mineral fertilizer for emergency and preventive boron supply. Used to supplement boron deficiency during the vegetation period for emergency and preventive application. Optimizes the uptake of nutrients from the soil and ensures stable vegetative growth.

Composition: 15% B in the form of boroethanolamine

Doses and application dates:

Winter oilseed rape: 1 treatment at a dose of 1.0 – 1.5 l/ha in the 6-12 leaf phase. No later than three weeks before winter dormancy.

VitaFer® Boron  mineral fertilizer for emergency and preventive supply of boron, phosphorus and nitrogen. Used to supplement boron deficiency during the vegetation period for emergency and preventive use. The use of additional nutrients in the Boron fertilizer increases the effectiveness of boron uptake by using the phenomenon of synergy.

Composition: 10.56% N + 13.2% PO + 9.24% B + 0.066% Cu + 0.132% Fe + 0.066% Mn + 0.00132% Mo + 0.066% Zn

Doses and application dates:

Winter oilseed rape: 1 treatment at a dose of 2.0–3.0 l/ha in the 6-12 leaf phase. No later than three weeks before winter dormancy.

VitaFer® Mn Complex  is an innovative foliar fertilizer containing 100% Mn (manganese) complexed with an organic factor (heptagluconic acid). Designed for emergency and preventive supply of manganese in the event of its deficiency. Recommended in particular for crops with a high demand for this nutrient, including: winter rapeseed oil, winter cereals, orchards and berry gardens and for crops grown on alkaline or freshly limed soils (pH above 6.0)

Composition: 5.95% Mn + 2.98% N

Doses and application dates:

Winter rapeseed oil: 1.0 – 2.0 l/ha in the 6-12 leaf phase. No later than three weeks before winter dormancy.
