Abstract
Lakes and streams may receive nitrate from waters draining from farm fields, hence it is important to minimize the nitrate level of these drainage waters. The objective of this research, conducted in the field, greenhouse and growth chamber, was to determine the principles controlling the level of nitrate left in the soil after cropping since this water is subject to leaching and moving into drainage waters. Comparisons among corn (Zea mays) at 4 populations, grain sorghum (Sorghum bicolor), forage sorghum, sudax (Sorghum vulgare) and wheat (Triticum vulgare) in field experiments showed that sorghum and sudax removed the greatest amount of nitrogen and had less unaccounted for when a nitrogen balance was calculated.
