| Urea has no real noted effect on yield UNLESS you get beyond 60 bushel an acre, there is data that indicates 60+ bushel soybeans can have an economic return with fertilizers. However, in my own experience, 100 lbs of 11-52-0 or 22lbs of N and 104 lbs of phosphate will give you a 3-5 bushel yield gain consistently with soybeans provided they are 50+ bushel which means timely rain for me. It's the best bang for your buck here but I don't do it on every field each year. Economics plays a big role in that. | |
