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.

Oilseed rape weed management has evolved over the last 10 years, mainly due to the challenge of establishing the crop with certainty and the introduction of more effective post-emergence broad-leaved weed herbicides. Before this development in chemistry there was a lack of flexibility - crops had to be treated early and all that was left was to hope for the best.

Today, there's more emphasis on sustainable, environmentally friendly crop production systems. As a result, cover and catch crops are becoming a widely understood and embraced method for aiding soil health.

With harvest just beginning, now seems a sensible time to draw breath and assess the season before harvest gets in full swing followed in short order by establishing next year's crops.

And what a season it's been. Yes, there have been weather events to talk about, especially the dry April and for some also the first half of May and most of June, but these pale in comparison to the economic impacts we've seen in the last 12 months.No more so than in my world of fertiliser, where an initial new season price for AN back in June 2021 - at 81p/kg N (£280/t) - was considered by some to be too expensive, only to then rise dramatically during the season to an eye watering £2.68/kg N (£925/t) at the peak.

At this time of year, I'm often asked: "How much nitrogen should I apply to my milling wheat crops?" My tongue-in-cheek response to that question is often: "Tell me exactly how much your crop is going to yield and then I'll be able to give you a guide on nitrogen rates." Now, clearly it is impossible to know the exact yield you are going to achieve at this stage so a definitive answer will always be hard but even so, I believe all milling wheat growers should fully understand the impact yield has on the nitrogen requirement for their crops.

Last year, I wrote a blog on how to increase nitrogen use efficiency (NUE) to improve your farm efficiency rating and part of this looked at the impact of nitrogen losses.Following on from this DEFRA recently announced a non-regulatory approach which outlines how to reduce ammonia emissions from any urea-based fertilisers.

To be frank, a sample bag of grain doesn't really tend to excite many of us. Why would it? It's just a sample, it's minute in comparison to the hard graft that's come before it. But then – if we really think about it – doesn't that make it quite a significant thing?

That bag of grain represents at least a year of hard work; significant investments, the challenges you've overcome and the opportunities you've taken. When you consider the efforts that have gone into creating that bag of grain you realise that, if we are to be completely honest, it all comes down to that bag. The fact is that it isn't just grain in there. It's information, data, learnings, it's proof of things that worked well and sometimes things that didn't.

The start of a new year is often when most of us traditionally think back to what has happened over the past 12 months before looking ahead at those to come.

Before Christmas, we published this news release announcing some exciting digital investments that have upgraded our variable rate nitrogen service for 2022. One of the most significant developments is the adoption of radar technology, meaning users can now access cloud-free imagery.

Maize is a high-value crop with a number of uses and so it is not surprising to see that the planted area is increasing year on year. With harvest now complete, it's a good opportunity to think about the learnings from this season as well as any steps you can take to reduce overwinter soil erosion and nutrient loss following removal of the crop.

"We're on a journey". That's what I say to my crop production customers when they see me take yet another set of tissue samples from the same fields that we started tissue testing over five years ago.

Over the years, I've formed a true partnership approach with my customers when it comes to crop nutrition. In the early days, soil analysis consisted of only measuring the most basic components: pH, phosphorous, potassium and magnesium. In addition, tissue analysis was taken sporadically here and there throughout the season.

​In the first blog of this soil management series, we're exploring why it's vital to start planning for soil management in autumn-drilled crops well in advance of planting; when the previous crop is still in the ground.

​The low levels of sulphur we see today are not a new problem. Rather, it is something we've been aware of for over 30 years; ever since the first sulphur-deficient oilseed rape crops were seen on very light soils. Over time, this deficiency has progressed and now impacts virtually all crops and soil types. By looking at the factors that influence sulphur availability, you can make informed decisions and opt for products that match your crops' sulphur demand.
