Sprinkler irrigation, furrow irrigation, subirrigation, automated subirrigation, criteria for applying irrigation water, methods of applying fertilizer and sources of fertilizer were investigated as to their potential to decrease possible pollution from nitrate and other solutes in a loamy fine sand soil overlying a shallow aquifer in Knox County, Texas. Less nitrate-nitrogen was available for leaching in subirrigation systems than furrow and sprinkler systems. Less irrigation water was applied with automated subirrigation systems than with the other irrigation systems. However, crop water requirement was not significantly changed--the soil water was more efficiently used. Subirrigation has the possibility of having irrigation return flow with lower concentrations of other solutes than sprinkler or furrow systems.
