YEN Nutrition

ADAS has developed YEN Nutrition to support growers in evaluating the effectiveness of their crop nutrition management plan.

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.

YEN

The Yield Enhancement Network (YEN) was launched in 2012 to support and energise on-farm learning-by-sharing and thus to enhance farming progress.

Nitrogen is required annually by most crops (except pulses) to achieve yield and quality. Judging how much N to apply is a key part of nutrient management.

Plants need around 12 essential mineral nutrients to grow: Nitrogen (N), Phosphorous (P), Potassium (K), Magnesium (Mg), Sulphur (S), Calcium (Ca), Iron (Fe), Manganese (Mn), Zinc (Zn), Copper (Cu), Boron (B) and Molybdenum (Mo).

Phosphorus (P) is an essential nutrient for both plants and animals, playing a key role in energy transfer as a major component of ATP. It is also vital in DNA. For full capture & conversion of solar energy, crop canopies need 30-40 kg/ha P. Crop species redistribute most of this P (~85%; more than for any other nutrient) to their seeds during canopy senescence, where it is stored as phytate. Plants appear to do this because, until their roots proliferate, plant seedlings are highly sensitive to P shortages.

The ideas behind Farm-PEP came together in ~2018, drawing from the developments of Agronomics, the YENs, AHDB's Monitor Farm programme and the idea of a 'What Works' Centre for Agriculture. 

Analysing grain for all 12 nutrients can be an effective tool to improve nutrient management, providing information on crop nutrient status and nutrient offtakes.  It can indicate whether your crops are getting hold of the nutrients they need, or whether you can save on future fertiliser use.

NRM’s GrainCheck service was launched in 2020 following several years of work with ADAS on the Yield Enhancement Network (YEN) project and to coincide with the RB209 recommendation for routine grain analysis. The test is suitable for cereals, oilseeds and pulses and should be interpreted alongside soil and tissue test results to give a full understanding of the effectiveness of crop nutrition programmes.

We are starting an ADOPT project with four farmers in Yorkshire to explore how we can make better crop nutrition decisions. Working with ADAS and the High Mowthorpe Farming Association and other local groups we are looking to engage more widely to gather and test ideas and experiences.
