Synopsis Urea‐N increased production of timothy approximately 5‐fold, irrespective of depth of water table and soil. Yields were about the same with water tables maintained at 2.5, 15, or 46 cm. as without a water table. Greatest yield occurred in lysimeters with 46 cm. of soil, 46‐cm. water tables, and N fertilizer. Within 2 years, Juncus balticus completely dominated nonfertilized timothy growing with 2.5 or 15‐cm. water tables. Formation of moss and a sod mat on the soil surface coincided with the appearance of Juncus .
