| few years ago I was fall applying fertilizer for next years corn and was right next to a field which was going to be beans the next year. I made a few passes into that field with the same rate as I was using for my corn ( this was n, p, and k). The next year I planted the beans and they were taller and greener all year long, but when I came with the combine it was only a bushel or 2 better, I believe this field averaged 45-50 that year.
One agronomist was trying to talk me into strip-tilling my bean ground with p and K, he claimed it was really going to make a difference. I did 3 replicated ways. 1 pass was strip-tilled, next pass I left strip-till up in the air but blew fert on top of ground, next pass no fert, I then repeated 3 times. When the combine came it again was statistically even across the strip-till, no-till with fert, and no-till without fert. I believe this field averaged just over 50 that year.
That said I still fertilize my bean ground so as not to be mining nutrients but I believe a good stand, no weeds, and timely rains in the fall is what makes a good bean crop. | |
