Some corn and soybean producers took a step this spring to help reduce the amount of phosphorous and nitrogen entering surface waters by participating in a no-till soybean and corn planting project.
Near-surface soil aggregate structural properties, such as aggregate size distribution, stability, strength and wettability, determine the extent to which a soil will erode under water or wind erosive forces.
The good news is that most of the Midwest's late-planted corn crop escaped serious heat or drought stress during the critical pollination period and, to date, much of the important grain-filling period, says Bob Nielsen.
