3 top tps for delayed soybean planting
As wet conditions further delay soybean planting in some areas, learn what practices may need to be adjusted and which don't to achieve a successful soybean stand.
Numerous soybean seeding rate studies have indicated that a final plant population of about
80,000 to 120,000 plants per acre is likely sufficient for ensuring an economic return, with the latter being based on weighing the slightly higher yield potential with higher final pl

A 4-Step Early Bird Guide to Higher Soybean Yield Potential:
Select full-season varieties with proven yield performance.
Know your replant coverage with seed suppliers and insurance.
Shoot for soil temperatures above 50°F during the 48 hours after planting.
Taking the soil temperature
Planting as early as possible allows your crop to collect solar radiation sooner; however, the practice comes with some risks which need to be weighed against the benefit.
