By using a combination of grain nutrient analysis of twelve essential nutrients, nutrient offtakes and benchmarking, YEN Nutrition provides a comprehensive review of nutritional performance. The three key areas it helps focus immediate improvement for the next season are:
- Detect fertiliser overuse
- Diagnose farm-wide nutrition deficiencies
- Identify potential savings
YEN Nutrition requires grain samples from six fields. However, they can be from any combinable crop. The results are converted into two reports:
The Offtake report: This is shared as soon as the lab and crop data are received. It contains the lab results for each field, calculates nutrient offtakes and informs whether values are considered: low, adequate or high.
The Benchmark report: This is shared from the start of December. It provides valuable context and comparison of yield and grain nutrition data against entrants from across the UK participating in the same season. This helps to understand performance and identify where improvements can be made in the coming year.
YEN Nutrition identifies both field-specific concerns and farm-wide issues. This enables growers to adjust their whole-farm nutrition management plans to better reflect crop needs. By identifying where excess nutrients have been applied, where additional amendments might be needed or identifying issues such as compromised rooting, which could be affecting nutrient uptake.
Years of YEN data from fields across the UK have allowed us to derive thresholds of concern which indicate the lower quartile value of all fields measured for each nutrient. This helps determine whether each nutrient is sufficiently supplied.
In addition to the above, the field nutrition is also compared to the RB209 offtake guidelines for P, K and Mg, which show where nutrient levels should be if best practice recommendations are followed.
Farm YEN Nutrition Reports can be ordered via the YEN portal. The cost for 2025 harvest season is £400 + VAT for six fields. Each additional field (or sample) costs £66.66 + VAT.
