If your soybean seed has been treated with fungicide, wait until just before planting to inoculate the seed. Of course for most economical soybean production, use a Cornell soil test to determine lime and fertilizer needs on your fields. Soybeans like a pH around 6.5. Your lime dealer can convert that into the specific limestones you have available so you get what you need. You can also use this to compare prices based on the amounts you will actually need to do the job.
Soybeans are an inexpensive crop as far as fertilizer goes.
Starter fertilizer bands should be at least 2 inches to the side and 2 inches below the seed. Don't use DAP or urea in the band. Soybeans are more sensitive to starter fertilizer burn than corn is. Don't manure the field the fall, winter, or spring before planting soybeans. Don't plant soybeans the first year out of alfalfa or grass.
