Growers have been asking about applying nitrogen (N) to soybeans. Soybeans have been shown to require more nitrogen than corn; roughly 5 lbs. per bushel, while corn requires only 1 lb. And 60-bushel soybeans need 300 to 350 lbs. of available N, about twice that of 200-bushel corn.

Nitrogen can be applied to soybeans preplant, top dress or foliar if there is a need, but often biological nitrogen fixation by the plant and supplies in the...

It’s another record year for soybean acres planted, as 10 - 15 percent of planned corn acres were shifted to soybeans due to the spring weather conditions. This record doesn’t come without challenges, though. Many of those acres will need special attention throughout the growing season.

Agronomy sales specialist Dawn Kielsmeier talks late-planted soybeans and how to best manage this year’s crop for a successful growing season.

Time to start watching for potassium deficiencies in soybeans

Soybeans require a whole lot of potassium (K) and remove a whopping 1.4 pounds of K2O per bushel. The application rate for a 60-bushel per acre soybean crop is 84 pounds of actual K2O or 140 pounds of potash (0-0-60) per acre. As we strive for 70- and 80-bushel beans that amount increases.

The first place to look for a potential potassium deficiency is a soil test....

Controlling problem weeds post-emerge in soybeans begins with pre-emerge planning.

The past few days have been filled with many service calls on both waterhemp and marestail control. These weeds are becoming major challenges in our crops and this season has proven to be one of the tougher one I have encountered in my career. The task of killing these weeds is already a challenge, but this season has been especially challenging. Here’re...
