Higher yield security in winter oilseed rape – DOMOGRAN® ammonium sulphate fertiliser 

Not only will you achieve a higher yield for your winter oilseed rape crop when you use DOMOGRAN® , you will also benefit from the additional effects that come from spreading this fertiliser. Higher oil content, better plant health and increased root growth are just some of the effects that can be expected from this coarse crystalline fertiliser. It is crucial for winter oilseed rape to have early access to nitrogen and sulphur in order to secure strong growth in the spring. The composition of DOMOGRAN® meets this requirement exceptionally well. The ammonium sulphate fertiliser provides readily available ammonium nitrogen and sulphur, and indirectly improves the availability of other nutrients. 

Benefits and effects of DOMOGRAN® as a winter oilseed rape fertiliser 

Beneficial root-shoot ratio 

DOMOGRAN®  contains ammonium nitrogen, which enables long-lasting ammonium nutrition of the oilseed rape plant. This has a positive effect on the root-shoot ratio. When roots grow prominently before the winter and the growth of epigeal parts of the plant is limited, you will benefit from robust oilseed rape plants that are extremely hardy. The plant will also reach higher levels of nutrient supplies through prominent roots and a larger surface area. The fertiliser can also be placed directly into the soil. This guarantees the effectiveness of the ammonia compared to distributed spreading.  

Crucifiers that require high levels of sulphur 

The varieties of oilseed rape available on the market today are no longer capable of storing enough sulphur, which means that you must ensure this element is permanently available in the root growing area. A lack of sulphur causes suboptimal nitrogen utilisation and impairs your plants’ metabolism. The protein, fat and carbon hydration engine starts to falter and the plant does not develop well. A lack of sulphur also reduces resistance to fungal diseases. DOMOGRAN® fertiliser enables you to feed your plants sufficient amounts of this critical nutrient, meeting their requirement for sulphur. 

Boron – the key to success 

It is critical for rape to have sufficient amounts of the micronutrient, boron, available. No other cereal crop has such a high requirement for this element (500 - 750 g/hectare) A lack of boron leads to restricted flower and seed formation, thicker stems and stunted growth. DOMOGRAN® makes existing nutrients, such as boron, more available to the plants in the soil, making it less necessary to apply special foliar fertilisers.

Applying DOMOGRAN® on winter oilseed rape 

Spreading in autumn 

You can fertilise directly while seeding with DOMOGRAN® or spread widely across the field using a centrifugal fertiliser spreader. During this season, the nitrogen requirement for oilseed rape is 30 kg/hectare, therefore we recommend a dosage of around 150 kg/hectare. 

Spreading in spring 

The mineralisation of sulphur from organic material only starts in April/May. However, oilseed rape needs sulphur prior to this. Therefore, depending on the weather and the stage of development of the oilseed rape plants, you should apply ammonium sulphate alongside the first nitrogen dosage, in order to meet the requirement for sulphur at the same time.


Did you know? Oilseed rape generates energy 

From natural cross-pollination to the famous yellow arable crop 

Oilseed rape is a popular arable crop in many countries with a temperate climate. Its yellow carpet of flowers can be admired primarily in the EU, Canada and India during the ‘fifth’ season, as oilseed rape is sometimes known. It all started with the natural cross-pollination of turnip with cabbage. Today's varieties of oilseed rape were established through targeted cultivation of this accidental cross-species. Oilseed rape plants have been cultivated and utilised by people for thousands of years. However, the plant was only cultivated on a large scale in Europe from the 17th century. Even then, it was primarily used to produce fuel for oil lamps. Rapeseed oil was only used for human consumption in specific cases at that time, due to its high erucic acid content and the bitter taste it created. It was only in the 1970s that the ‘00’ oilseed rape variety was cultivated to minimise the erucic acid content. Today, oilseed rape is well established as a human food source, and is also used to produce biodiesel and high-quality protein fodder for farm animals. 


Oilseed rape - paradise for bees 

Farmers and beekeepers both benefit. Bee colonies present around oilseed rape fields provide widespread pollination of the flowers. They are one of the most important factors for a successful harvest. Honey produced from oilseed rape flowers is particularly sumptuous. 40 kg of honey can be produced from one hectare. Yet the yellow flowered cup only overflows with nectar from mid-April to the beginning of June.
