+2026 Notes
+Agar, SD -— Extremely good yield, especially with the overall limited precipitation. Stands were not perfect due to planting into spring wheat
+residue, but data was clean nonetheless.
+Presho, SD — Good yield despite drought stress showing at times and some noticeable freeze damage. Similar to Agar, stands were
+impacted by planting into spring wheat residue.
