How much nitrogen does it take to produce a bushel of soybeans?
It takes roughly five pounds of nitrogen to produce one bushel of soybeans. Normally, soybeans can get most of their nitrogen from the air, although this year we have heard several reports of less than optimum nodulation on soybeans. When nodulation appears to be a limiting factor, researchers suggest that 50 to 75 pounds of nitrogen per acre by blooming time may boost yields. Sulf-N ammonium sulfate (applied straight or in a blend with urea with a urease inhibitor) is an efficient way to achieve this task.
