university soybean trials conducted in North and South Dakota have included
planting date comparisons. During 1999 to 2001, a soybean production trial was

During May 8 to 14, area moisture (rain and snow) amounts ranged from 1.2 inches at McLeod to 0.12 inches at Linton as recorded at NDAWN sites. Most of the region received about 0.5 inches or more of moisture. Black soil temperatures at the 4-inch depth ranged from the upper 40's to low 50's F on May 14. Fieldwork should be in progress throughout this week of May 13.
There continues to be a wide spread of seeding progress between counties north of I-94 compared to counties near the South Dakota border, as of May 15. In the southern counties, small grain seeding is nearly complete and corn should be finished at week=s end. Small grain fields seeded in April generally have emerged. Soybean planting is in progress and dry bean and sunflower planting will start soon. In Eddy, Foster, Sheridan and Wells counties, 25% or less of small grain, canola, and flax seeding is complete. General concern exists with timely seeding of corn and cool-season crops. This may mean a likely increase in soybean and sunflower acres for this northern region. Wild oat and other early-season weeds are emerging.
