YEN Nutrition allows you to Know your Nutrition, through grain analysis of nutrients and benchmarking of data. YEN Nutrition supports the diagnosis of nutrient deficiencies and the identification of opportunities for fertiliser savings, leading to balanced crop nutrient management. Benchmarking facilitates comparisons to be made between crops, fields and farms, helping to justify future decision making to maximise profitability.
Join YEN Nutrition
YEN Nutrition membership costs £250 +VAT. This provides analysis and benchmarking of six fields (or samples). Additional samples cost £40 + VAT.

Why analyse grain nutrients?
Grain analysis defines a crop's final nutrient status. It accurately assesses nutrient offtakes and then benchmarking identifies which nutrient deficiency(ies) may have limited the crop's yield.
Grain analysis provides levels of all 12 essential nutrients: Nitrogen (N), Potassium (K), Phosphorus (P), Sulphur (S), Calcium (Ca), Magnesium (Mg), Manganese (Mn), Zinc (Zn), Copper (Cu), Iron (Fe), Boron (B), and Molybdenum (Mo). It completes the story started by soil analysis and developed by leaf analysis and reveals whether a crop actually captured enough of each nutrient throughout its entire life.
Grain analysis provides a check on: -
- Results of soil and leaf analysis
- Seasonal abnormalities
- Whether rooting etc. was adequate
- Whether nutrient sprays worked
Grain analyses on >900 YEN cereal crops showed that three-quarters were probably deficient in at least one nutrient. We estimate that the average YEN crop would have benefited at least £500 per field if it had received fully optimal nutrition.
Along with known yields, grain analyses also provide the most accurate estimates of crop nutrient offtakes, hence P&K requirements. This reduces unnecessary nutrient applications and on average saves on fertiliser costs by ~£50 per field.
Routine grain analysis is now recommended in AHDB’s Nutrient Management Guide (RB209), the go-to guide for growers.
The importance of benchmarking
By also benchmarking your grain results against results from other crops, you can immediately see how well your crops’ nutrition ranked.
As more farms become involved in grain nutrient benchmarking, understanding of crop nutrient levels and yields will improve for all farms.
Our end-of-season overview of entrants' nutrition data from 2020 showed major differences between farms. Data from 2021 will check these conclusions and show how attention to nutrition should generally be best focussed in future farm by farm.
The YEN Nutrition process
Once you have entered, you can add your farm, field and crop details through the YEN Nutrition Portal, which then helps you manage your entries, share your results (anonymously) and benchmark your fields. The process will be to ...
- Enter your farm details (if you are new to YEN)
- Choose your lab and your sample kit delivery address
- Enter the fields you wish to sample, and sample names
- Provide information about your crops, soils, and fertiliser inputs
- Receive a harvest sampling kit - please allow 10 days for this to arrive
- Take samples from each load as each field is harvested (instructions in your kit)
- Send all samples using bags provided in the kit to your chosen lab.
- Enter (on the YEN Nutrition Portal) the yield for each field and whether straw was removed
- Receive your reports, benchmark your results, highlight key issues, and better manage the nutrition of your next crops.
Results (example Reports from 2020):
- Nutrient Offtake Report - available shortly after samples and crop yields are provided
- Nutrient Benchmarking Report - available in November
- Seasonal Summary - available in March, only to data providers
- Annual Review - available in April (on request)
- And - new this year - you may use YEN Dynamic Benchmarking online
All YENs are also providing members with increasing opportunities to form or join groups to 'learn by sharing'.
We propose that farms with common links (e.g. the same agronomist, the same soil or region) should benefit from forming Nutrition Clubs to
- share and discuss (via Whatsapp or winter meetings) results from their nutrient management and crop analyses,
- get expert nutritional guidance, and
- agree on questions that members could test.
ADAS is keen to help members to obtain sponsorship or funding for these Clubs. Please email firstname.lastname@example.org to access this support. See the 'YEN Nutrition Club Flyer' (in Resources) for further details.
