Also, continous corn plots receiving, swine manure applications resulted in significantly higher NO3-N concentrations in subsurface drain water although, the use of the swine manure corn-soybean rotation has the potential to reduce negative water  quality impacts significantly.  Rotation plots showed over time a more consistent NO3-N concentration when compared to continous cropped corn, concentration ranged from 9 -13 mg\/l for liquid fertilizer plots and 9 - 15 mg\/l for manured plots.  Concentrations for the rotated plots were lower than for conrinous corn because fertilzer and swine manure wqas applied every second year.  This study shows that high manure application rates canb result in high NO3-N concentrations in drainage water, aslso high drainage volume resulted in greater NO3-N losses with continous corn than rotation practices.  This shows precipitation is a major factor in nitrogen leaching losses to shallow groundwater.\n<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The results indicated that altrernative cropping systems like strip cropping alfalfa resulted in the lowest NO3-N concentrations (< 9mg\/L) in the shallow groundwater in comparison to manure and other N treatments.
