The influence of irrigation frequency on denitrification was studied on a Yolo loam field profile at Davis, California. Two carbon treatments were also established by using plots with and without incorporated crop residues. Irrigation frequencies of three irrigations per week, one irrigation per week, and one irrigation every two weeks were established on areas cropped with grass. Fertilizer was applied as KNO3 enriched with 15N to 1-sq m plots. Denitrification from the least frequently irrigated treatments was less than that in the most frequently irrigated treatments. Denitrification of NO3(-) fertilizer was simulated using a mathematical model that included transport and plant uptake of water and nitrogen in soil.
