Editor's Notes
- 1. Title slide โ while title slide up do introductions of Karen/EDF, John/S Squared NutrientStar developed by EDF, in collaboration with NUE experts, consultants and S Squared. EDF ag sustainability has as a goal to optimize fertilizer use on 45 million acres in the US, with the Upper Mississippi and Lake Erie basins as focus areas. Major points: NStar is objective โ nobody has a stake in the outcome. The evaluation questionnaire, protocol for data and criteria for certification have all been developed by the NutrientStar review panel after months of deliberations Goes beyond certification โ is more than just certification, we added the word โeducationโ to convey this. It is geared toward those tools that claim to deliver NUE benefits OR a system of benefits โ the 4Rs is a good way to look at these โ which of the 4Rs does the tool or product address โ we are evaluating those claims. The program is designed to evaluate company claims and educate farmers about the presence or absence of data supporting those claims as well as how some of these tools might best be used or deployed and under what circumstances they may deliver greater or lesser NUE benefits. Whatever the company brings โ if the tool brings a system then we evaluate on that system. The full NutrientStar program is still in development and will continue to evolve
- Goals of NStar And economic impact โwe recognize this is important Underscore second and third bullets: currently there is no one place farmers can go to find information โ data, research โ about NUE tools. NutrientStar will build capacity through on-line presence for that one-stop shop of information Will also provide meaningful tools to industry โ e.g. regional maps that can guide field research and identify broadest audience

- 6. Review panel Recruited after recommendations from ag consultants and partners (why did we pick these people โ critical thinkers, as the important questions, independence, recognized as experts on the basis of their published research and work on the subject) Both practitioners and scientists Will be recruiting farmer members Panel members resolve scientific and technical issues and questions, review submissions, help determine educational aspects. Confidentiality agreements and non-disclosure of information agreements, also cannot be developing or contemplating developing any tools or technologies. The panel conducts its business through bi-monthly teleconferences and email.
- 7. Focus: (John) Again, emphasize that we are evaluating DSTs and products based on their claims. Looking at technologies that consider the 4R system โ some modeling techโs do help farmers evaluate their N program from rate, timing and placement โ are these recommendations helping farmers? Optical sensors โ rate, timing, placement. Some look at form as well. NStar promulgates research protocols that could be used to measure the 4Rs, and can be adapted to evaluate any combination of practices/technologies/products.
