In trials conducted through the Nebraska On-farm Research Network (NOFRN) in 2017, several farmers evaluated alternative nutrient supply products and practices. Short summaries for these trials are presented below. Most trials were conducted once, which generally is not sufficient for conclusive results; however, the information is valuable when considered with other information. Full details of the trials are available in the 2017 Growing Season Results report published by the NOFRN. Reports for years prior to 2017 are also available.

1. Two studies for organic corn production compared Nature Safe at 150 and 300 lb/ac, Beju at 100 lb/ac, Humic DG at 10 lb/ac, and an untreated control. The mean yield was 192.1 bu/ac and there were no differences in yield between the treatments.
   Individual site reports are available on pages 89-93 of the 2017 report; reference study ID numbers: 641047201702 and 641047201703. This research project was conducted by Extension Educator Sarah Sivits.
   
   
2. Three studies of 65 to 85 lb/ac N applied to soybean at R2 had an average yield of 70.8 bu/ac with an average increase in yield of 1.8 bu/ac compared with an untreated control. Results at each of the three sites were varied.
   Individual site reports are available on pages 95-101 of the 2017 report; reference study ID numbers: 735135201701, 736111201701, and 741029201701. This research project was conducted by Extension Educator Strahinja Stepanovic.
   
   
3. Foliar application of Kip Cullers’ Nutrient Compass to soybean was evaluated in one trial. The mean yield was 70.5 bu/ac; the applied product showed no effect.
   Individual site report can be found on page 102 of the 2017 report; reference study ID number: 319039201702. This research project was conducted by Extension Educator Aaron Nygren.
   
   
4. CoRoN® applied to sorghum at boot stage was evaluated in one trial. The average yield was 110 bu/ac with no effect of the product. There was a pre-plant application of 130, 46, and 3 lb/ac, respectively, of fertilizer N, P₂O₅, and Zn.
   Individual site report can be found on page 103 of the 2017 report; reference study ID number 009129201701. This research project was conducted by Extension Educator Jenny Rees.
   
   
5. One site where soybean with iron chlorosis had a mean yield of 78.3 bu/ac but yield was not affected by: application at V2 of Toggle, Max-IN iron, or Toggle + Max-IN iron; or by application at planting of Aurora Bean Starter or Toggle+IronForce-H.
   Individual site report can be found on pages 104-105 of the 2017 report; reference study ID number: 722121201701. This research project was conducted by Extension Educators Steve Melvin and former Nebraska Extension Educator Michael Rethwisch.
   
   
6. Soybean yield was not affected in one trial due to application at 5 gal/ac of Opti-Start Gold, a six-nutrient starter fertilizer.
   Individual site report can be found on pages 106-107 of the 2017 report; reference study ID number: 027025201701. This research project was conducted by Extension Educator Keith Glewen.
   
   
7. In one trial corn yield averaging 282 bu/ac was not affected by starter fertilizer products including 9-24-3, 9-24-3+Prolock, R8-24-3, Levitate+10-34-0, 10-34-0, or 10-34-0+Accomplish.
   Individual site reports are available on pages 108-109 of the 2017 report; reference study ID number: 686035201701. This research project was conducted by Extension Educator Jenny Rees.
   
   
8. In another study corn yield was increased by 13 bu/ac for starter fertilizer 10-34-0+Zn compared with an untreated control.
   Individual site reports are available on page 110 of the 2017 report; reference study ID number: 708077201701. This research project was conducted by Extension Educator Troy Ingram.
   
   
9. Application of Kickoff (a six-nutrient fertilizer) and Kickoff+Optify/Stretch to soybean in one study did not result in a yield difference compared with an untreated control.
   Individual site reports are available on page 111 of the 2017 report; reference study ID number: 218023201701. This research project was conducted by former Nebraska Extension Educator Michael Rethwisch.
