The GNB survey is open to all farms able to provide field-specific samples of any cereal crop harvested in 2017, and (if insufficient samples) then from harvest 2018.
Grain analysis should tell you whether your crops got enough of each nutrient throughout the whole season (as well as nutrient offtakes).
What you need to do:
1. Work out how many samples you can provide; ideally two to six samples per farm, with a good contrast in growing conditions e.g. different soil, soil P Index, or yield. However, single samples are OK, and multiple samples may be possible.
2. Email eWVuQGFkYXMuY28udWs=, indicating the number of samples you can provide.
3. Fill in a form (which we will send) with farm and field details (e.g. soil Indices and yield)
4. Send grain samples to Yara, in the labelled bags which we will send you.
