Corn Plant Average Yields

By Dr. Harold Willis

High yields start with good seed and a good soil management system.

The very most basic thing for growing really good crops is good soil. Soil that is not only high in fertility, but is alive with beneficial organisms. The ideal soil for growing corn is deep (six or more feet), medium-textured and loose, well-drained, high in water-holding capacity and organic matter, and able to supply all the nutrients the plant needs. Of course, not everyone has the per­fect soil, and corn isn’t so fussy that it can’t do well on less than ideal soil.
