Fertiliser quality - don't settle for less
Soil fertility is certainly top of both farmers and policy makers minds currently, with a broad consensus that it plays a key role in the continued economic and environmental sustainability of farms.

Keeping clover in fine fettle
White clover is being increasingly used on intensively grazed farms where the benefits can be substantial, lowering both the cost of growing grass and the carbon emissions intensity of milk produced. Managing nutrient and fertiliser inputs is a key component in establishing and maintaining clover in these swards successfully.
Canola Fields
Sulphur: Best Practice
It is widely accepted that UK soils are deficient in sulphur so supplementation via organic manures or mineral fertilisers is essential. What I think is less understood is that not all sulphur-containing fertilisers are the same.

Improve Potato Quality with Calcium
Did you know that up to 50% of wheat leaf samples show a deficiency in zinc, magnesium, copper and manganese?

Grassland Grazing Tips for May to June
We’re heading into a busy period for grassland farmers and as ever, the weather can change everything in a heartbeat. Here are a few things to focus on throughout the rest of May and heading into June.

Stimulating Growth by Enhancing Nature
Yara’s expertise isn’t solely focussed on NPKS fertiliser development, over the years Yara have worked hard to reduce our impact on the environment as well as developing more sustainable products.
Three people walking through a Scottish farm
Walk your Fields
Throughout April and into May we’ll be focusing on optimising grass growth to meet the demands of our grazing cows so that we can maximise grazed grass in the diet.
Wheat Field
Help Late-Drilled Wheat Crops Catch Up
Did you know that up to 50% of wheat leaf samples show a deficiency in zinc,magnesium, copper and manganese?
Carrots in a field
Maximising your vegetable crops’ potential with foliar nutrition
With the amount of rainfall we've had, a lot of the nutrients in the soil will potentially have leached away.

Read about improving nutrient efficiency

Grow the future | Kickstart early spring grass | Farmer inspecting grass
Kickstart early spring grass with a nitrate based fertiliser
Applying early nitrogen as nitrate will get grass off to the best start, but if you combine this with urea you will get more flexibility without having to worry about the weather.
Grow the future | Grassland sulphur management | Farmer inspecting grass
Managing grassland sulphur delivers impressive results
Managing grassland sulphur doesn’t need to mean big changes. Simply switching fertilisers can deliver impressive results.
Grow the future | Silage fertiliser | Farmer inspecting grass
Avoid compromising your silage with poor nutrition
Don't risk compromising the yield or quality of your silage by cutting corners with your fertiliser programme
Grow the future | Grassland selenium fertilisers | Farmer inspecting grass
Preventing selenium deficiency avoids reduced productivity
Grazing animals have a requirement for selenium so it is important sufficient is present in the grass to meet the animals' needs to prevent selenium deficiency problems.
Grow the future | Forage maize foliar nutrition | Farmers watching maize harvest
Paying more attention to forage maize nutrition pays off
Paying more attention to forage maize foliar nutrition, particularly phosphate and zinc will improve crop establishment and early growth resulting in higher yield and better quality forage.
Grow the future | Nitrogen and sulphur fertiliser| Agronomists in wheat field
Applying nitrogen and sulphur together just makes sense
Combining nitrogen and sulphur together increases nitrogen use efficiency so means more for your money with less wastage.
Grow the future | Compound CCF fertiliser | Agronomists in wheat field
A compound fertiliser is so much better than a blend
When you apply nutrients using a complex compound fertiliser (CCF) you avoid the risk of segregation and uneven distribution that you get when using a blended fertiliser.
Grow the future | Phosphate and potssium | Agronomists in wheat field
When it comes to P and K doing nothing is not an option
When it comes to P and K doing nothing is not an option. Potassium and phosphate are two essential plant nutrients with the plant requiring a consistent supply from the soil during the critical spring growth period.
Grow the future | Spring arable nutrition |
Spring nutrition must keep crop momentum moving
When winter cereals begin spring growth keeping that momentum going should be the main focus of the spring nutrition strategy
Grow the future | Cereal micronutrients | Agronomists in wheat field
Cereal micronutrients can prevent yield losses
If you supply your cereal crops with exactly the right micronutrients where and when they are needed this will prevent yield losses or quality reduction due to deficiencies.
Grow the future | Potato nutrition
Better nutrition improves potato yield and quality
Making sure your potatoes are fully supplied with all the nutrients they require is the best way to improve crop yield and tuber quality
Grow the future | Soil testing and tissue analysis
Soil and leaf testing avoids wasting money on fertilisers
The best way to avoid wasting money on fertiliser is through soil testing and tissue analysis and then understanding what the results mean.
