Why Choose Liquid Fertilisers for Oilseed Rape
Accurate Nutrient Placement
Liquid fertiliser delivers nutrients evenly across the field, ensuring every plant receives the nutrition it needs from your oilseed rape fertiliser.
Backed by research
Our oilseed rape nutrition programmes are developed through decades of research, field trials and technical farmers confidence in proven crop nutrition solutions.
Reliable Supply When It Matters
With one of the UK’s largest liquid fertiliser distribution networks, 11 nationwide hubs and 540,000 tonnes of storage capacity, we help ensure product is available when your crop needs it most.
Supporting Establishment
Early nutrition is essential for successful oilseed rape establishment. Liquid fertilisers provide readily available nutrients to support rapid rooting, healthy early growth and a strong foundation for the season ahead.
Nutrients and Deficiencies in Oilseed Rape Crops
Oilseed Rape Crop FAQs
-
Ensure your oilseed rape crop gets off to the best start utilising liquid nutrition, usually placed near the seed that’s instantly available to the crop. Nutrients in a liquid form are immediately available for plant utilisation, unlike granular alternatives. It’s also key you understand the soils nutritional profile, and what’s available for crop growth, ensure you’re conducting routine soil analysis.
-
Yes, foliar applied nitrogen has been demonstrated to improve yield in oilseed rape yield. Utilise a formulation such as Oilseed Extra that’s been researched, tried and tested to ensure you’re applying a quality formulation capable of delivering a respectable return on investment
-
Firstly, it’s key you understand the agronomic and financial expectations of the crop. On-farm sustainability must include financial sustainability so utilising a programme that delivers environmental alongside financial benefits is key. Ensure you understand your soil, promoting soil health and ensuring your indices do not go below index 2.
During active growth utilise SAP analysis so you can gain a true understanding of the nutritional status of the crop, this will ensure you only apply what is absolutely necessary for the crop, not over or under utilising inputs available to you. It’s also important to promote plant health throughout the growing cycle. A healthier plant is much better able to withstand the many stresses it faces throughout its life. Consider utilising inhibitors when growing your oilseed rape crop, making your fertiliser applications more efficient.

When used as part of a well-managed crop nutrition programme, liquid fertilisers can support stronger establishment, improved nutrient use efficiency and consistent crop performance. Combined with the correct application timing and rates, they help growers maximise yield potential while using nutrients more efficiently.
Multiflo Base N P and K for Oilseed Rape
It’s important that soils growing oilseed rape are maintained at P and K indices of 2 or above to produce effectively. Ensure you’re utilising a soil sampling service to check you’re not under, or over applying, key nutrients – helping you grow oilseed rape more sustainably and financially viable.
Multiflo has a variety of grades available for optimum growth, demonstrated below, however you should keep in communication with your local FACTS qualified advisor to make sure you’re utilising the best grade for your crop.

Multiflo Grades for the full NPKS requirement
9:9:9 +S
Application of 30 kg/ha NPK plus sulphur is an excellent approach to maintaining indices and aiding good establishment and all Multiflo grades are available with sulphur to improve the efficacy and uptake of the nutrients applied to the crop.
If different ratios of P and K are required, according to soil indices, different products are available for application, along with the standard 40 kg/ha nitrogen applied for establishment.
Multiflo N+P Starter Fertilisers for Oilseed Rape Establishment
Nitrogen and Phosphorus are key elements to aid rapid Oilseed Rape establishment. OMEX have researched the most effective formulations, timings and application methods to aid with starter fertiliser establishment.
In the trial below, conducted at Agrii’s iFarm, OMEX’s Multiflo grade 14:14:0 provided the best outcome at harvest, with it’s instant uptake liquid formulation out-performing the granular alternative.
The OMEX 14:14:0 gave the highest final yield, +0.54 t/ha (+19%) over the untreated control, and +0.22 t/ha over the next best treatment. Utilising Farmers Weekly (LINK 3) crop spot prices at the time of trial the economic return of utilising the Multiflo NP starter fertiliser for Oilseed Rape was as follows:
Economic Return:
Cost of application, 60 l/ha 14:14:0 on the drill £22.00/ha
Additional yield 0.54 t/ha @ £297/tonne * £160.38/ha
Net Return £138.38/ha
Return on Investment 7.3 : 1
Soluble P for Oilseed Rape Establishment
Phosphorus is prone to lock up in soils, particularly in high pH and magnesium-rich soils. As phosphorus is key in oilseed rape establishment ensuring it’s applied in it’s most available form will benefit the crop agronomically, and the ROI financially.
Multiflo has been expertly formulated to contain a 100% soluble form of phosphorus, making it immediately available to the crop upon application.
The longer the phosphorus remains in the soil, the more unavailable it becomes to the crop. OMEX has developed Polymex a unique additive that helps the phosphate remain available to the crop for longer.
Multiflo Trials
Trials conducted utilising Multiflo grade 7:20:0 starter fertiliser on winter oilseed rape, demonstrated a positive response to the inclusion of Polymex, improving the overall oil yield of the harvested oilseed rape crop.
The trial, ran in collaboration with Crop Intellect (link 5) identified the Polymex treatment as the most effective, offering the best economic benefits to the oilseed rape crop.
The following images captured during the trial demonstrate the improved rooting response from the inclusion of Polymex with the NP starter fertiliser for oilseed rape.

Nitroflo – Nitrogen and Sulphur for topdressing Oilseed Rape
Oilseed rape crops require spring applications of nitrogen and sulphur for top dressing, and can be split into two applications. However, a single application can be made utilising the nitrification inhibitor DIDIN.
The OMEX Nitroflo range offers accurate liquid NS fertilisers for oilseed rape crops – offering the many benefits liquid fertilisers have to offer. The quality nitrogen grades are available with sulphur to aid uptake and assist in remedying deficiency, particularly in traditionally deficient soils.

Foliar Nitrogen for Oilseed Rape
Nitrogen is key to maintaining oilseed rape canopy, pod and stem greenness to produce yield. Oilseed rape doesn’t take up soil nitrogen after flowering meaning foliar applications of nitrogen are essential, to maintain crop performance and photosynthesis to fill the potentially large numbers of seeds set.
For the best results, foliar nitrogen should be applied at the end of flowering (after 90-95% petal fall) using normal spray nozzles to coat the pods, stems and upper leaves. Checking the crop for nutrient levels with SAP Analysis will give you an in-depth analysis of what nutrients the crop is lacking, and an agronomist will advise on the best course of action for your crop.
SAP Analysis
Oilseed Extra
Oilseed Extra is a foliar spray containing nitrogen, sulphur, magnesium and key micronutrients to improve efficacy and uptake. Oilseed Extra is utilised to boost oilseed rape yield by boosting the nitrogen content during the critical pod and seed development stages, and provides a greater yield increase than with simple foliar nitrogen, such as urea alone.
In trials Oilseed Extra gave double the increase of straight urea. In 26 positive trials the average yield response in oilseed rape was 0.3 t/ha to 40-50kg of N applied at or after flowering.
