DWM, row spacing on soybeans is something I have noticed for several years. I see some planting on the 30" while some drill at 15" or maybe less. It seems from an agricultural perspective that more rows equals more beans in the field. If they grow, and grow well on 15" why plant on anything else.I see that 30" rows will take until later in the growing season to reach a full canopy which may require spraying twice. I do realize some soils may not support high numbers per acre and your planter could be the factor also. But Ive seen some beans growning well in some fields you wouldnt think would grow anything. How do you determine areas that will support high numbers and narrow row spacing? I would think its based on the soil test and if its bottom land.
