I assume that you are in Iowa. There are three things that I am thinking about when planting soybean on soybean (SCN, fertility, and bean leaf beetles). If you have confirmed SCN on your farm you will need to plant a SCN resistant variety for sure. 

Be sure that you don’t have deficiencies of P and K on your farm so a soil samples should be taken and follow your local extension recommendations on that. 

Finally, if you had bean leaf beetles in your field late in the season last year and saw pod feeding, then be sure than you are out there monitoring them this spring. The cold weather that we have now probably doesn’t do a lot to them since we have a nice snow cover throughout Iowa.
