Following on from a previous blog about early nutrition strategies, unfortunately due to continued wet weather there has been limited opportunity to complete many field applications. For some, this has been very 'stop/start'. For others, it's been absolutely impossible to get out in the field.

Many of you will be looking for guidance on how to manage the impacts this is having on farm. Let's look at some pointers on how to keep an eye on crop nutrient health as we enter into a period of peak applications and big biomass growth.

Many of you will be aware of the urea stewardship scheme due to come into force in England from 1^st April 2024, however, for some there are still questions as to what the new regulations include.

Back in May 2023 when an early announcement was released about the rules, I outlined everything you needed to know. In this blog, I think some of that information is worthy of a recap, particularly why Defra is focused on the stewardship of urea fertilisers, as well as a reminder of what you need to do in certain scenarios to stay compliant with the regulations. 

Last year I shared some advice in this blog about managing sugar beet to optimise yield, and in it I contemplated what kind of results the autumn was going to bring given some of the widespread late planting we saw.

Now that we're well into 2024, it was great to see the majority of sugar beet crops doing well throughout the tail end of last year. However, for many crops harvest was delayed until January 2024 due to the wet autumn and frosts in early December. 

As the season has been so challenging, it's great to be able to demonstrate the positive results from our variable rate nitrogen (VRN) trials which can make a difference on farm. In this blog, we'll be talking through the benefits and value of this technology, as well as how the findings from the trials can be replicated on your farm to achieve the same positive results.

The recent wet and mild conditions have brought early crop nutrition into sharp focus and you may be looking to address some of the negative impacts on any autumn-drilled cereal crops.

During autumn 2023, most of the UK experienced significantly above average rainfall and this depleted soils of any residual nitrogen. There's also no doubt that rooting was compromised due to waterlogging. 

This blog is a combination of insights and guidance for crop nutrition, variable rate technology and biostimulants – all of which can play an important role in your spring strategy to boost biomass and maximise profit margins. If you follow some of the below guidance, any lacklustre crops should stand the best chance of turning things around in time.

Last month, I had the privilege of talking about Frontier's closed transfer system (CTS) at LAMMA as part of the event's Live Theatre sessions. I was thrilled to be able to bring this innovative piece of technology to the show, highlighting the benefits it's already bringing many farmers and sprayer operators at a time when on-farm safety, product stewardship and sustainable farming are extremely important.

While at the event, I had great conversations with visitors about the equipment – many of whom had questions about the technology as well as the practicalities of adopting it on farm. I thought it'd be great to reflect on these discussions here and explain why the closed transfer system is proving such a valuable solution for many growers.

During the recent visit from Storm Babet, exceptional levels of rainfall fell in a short period and saturated a lot of land in many parts of the UK. The concern now – particularly with more rain on the way – is the interruption caused to drilling progress, with some fields already destined for spring cropping. Crops drilled more recently have also been affected by waterlogging and significant runoff, which causes ruts and the loss of seed.

If you've found you're experiencing some of these issues in the aftermath of such severe rainfall, you're probably wondering what the best course of action is. Depending on your situation, there are a few options that could still mean you're able to get a crop in the ground and off to a good start. 

This autumn, oat growers across the UK face new crop management considerations following the news that the pre-emergence herbicide, Liberator (flufenacet + diflufenican), can no longer be used on the crop.

The change comes after oats were newly categorised as a 'major crop' by the Chemicals Regulation Division (CRD), meaning all Extensions of Authorisation for Minor Uses (EAMUs) have now been revoked. This leaves growers with no residual herbicide options apart from Sempra XL, though this can only be used on oat crops which are being grown for seed.

Despite recent challenges, oilseed rape (OSR) remains a profitable break crop which can also aid grassweed control in your rotation. Of course, success is dependent on good establishment, which in turn relies on strong attention to detail.

Although recent weather patterns may have presented some difficulties for other combinable crops during the harvest period, there is a silver lining in that the increased soil moisture will aid seedbed preparation and drilling. 

Choosing a grass reseeding mix can be tricky. Even so, the phrase "No, surely its simple" is one I often hear, as well as assumptions that "one field of green is the same as the next." However, with the quality and diversity of work carried out by plant breeders over the last 70 years or so, each field really is different in terms of output.

This season the spring weather has aided the establishment of good sugar beet plant populations, which is very positive for final yields. However, the average planting date was much later than we've experienced for many years. Importantly, crops have good potential but their management may need some adjustment from now until harvest to achieve optimum yields.

'Versatility' has become 'the norm' for many people across the globe following the many and varied extreme events of the past four years. More specifically within UK agriculture, there have been the challenging unseasonable weather patterns during autumn and spring. These have affected growers' annual cropping plans, key agronomic timings and fertiliser applications.

DEFRA's consultation on reducing ammonia emissions from urea fertilisers closed in January 2021, but it wasn't until April of this year that the outcomes were clarified. 

Now that we can consider all the details, I've outlined some Q&As to offer more context to the new regulation and what it aims to cover.

Cover cropping has become a common practice within arable rotations and as spoken about in previous blogs, this is due to the many benefits they can bring to soils. Given the current volatile fertiliser market, however, today there is much more interest in their ability to capture nutrients, particularly nitrogen. We mustn't forget the range of habitat they also provide for various insects and wildlife.

February - the month for late snowfall, frosts and in some areas welcome rainfall. Wherever you are in the UK, there will be different challenges as the days lengthen. Some of those challenges are 'the office jobs' you thought you had plenty of time for but now you have more daylight, there is the temptation to shelve those tasks and get on the field. Countryside Stewardship (CS) and Environmental Land Management scheme (ELMs) application windows also open around this time, adding even greater temptation to park those jobs.

At this time of year, attention turns to upcoming activity on farm. First on the list will be early nitrogen applications, but before they happen it's important to consider what could impact them and any subsequent applications to ensure you make the most of your nitrogen fertiliser.

As we've mentioned before, the only real way to measure the effect of nitrogen is at the end of the season when we have the opportunity to analyse grain on an individual-field basis. From this, the findings can highlight the specific adjustments needed for the following season.

Frontier and SOYL Precision's field grain analysis service gives interpretation over all the essential nutrients to make sure you as a grower get the most from your data. In this blog, I'll focus on the nitrogen analysis results from this year's sampling.

Good establishment of spring crops is critical for optimising yield and getting them off to the best start also provides well-known cultural grassweed control benefits. Spring may seem a long way off but with some growers opting to drill spring wheat and barley in late autumn or early winter, considering everything from seed rates, weed control, soil management, nutrition, pests and disease will stand crops in good stead for the season.

There are good reasons to introduce home-grown nutrients into your nutrition plan. For one, if enough nutrient can be grown and captured, there is potential to increase business margins. However, the two benefits of most interest are: the degree of protection it can offer from a volatile fertiliser market and the potential to reduce carbon emissions on farm through a reduction in applied fertiliser.

If you've drilled your wheat crop early this year, you may be wondering how to mitigate the challenges that tend to become apparent at this time of the season. Grassweeds, barley yellow dwarf virus (BYDV) and the crop's general nutrition are important to keep on top of when managing your crop.
