Abstract	We first need to note that the soil nitrogen that makes plants green is primarily in the form of nitrate, and this nitrogen is accessible to plants specifically because it stays dissolved in the soil water. In a typical corn field, where the bulk of the roots are in the top 18 inches of soil and the soil has a water-holding capacity of 25 percent, the corn root zone can hold 4.5 inches of water. If the farmer adds an extra 4.5 inches of water during the year on top of what is needed to wet the soil, essentially all the soluble nitrogen will be pushed out of the root zone.
