초록
This experiment was conducted to investigate the effects of the addition of wintering waterfowl’s feces prior to planting rice on nutrient dynamics, rice growth, and decomposition of rice straws in a controlled mesocosm. Waterfowl’s feces and rice straws were placed on paddy soils in a mesocosm and the water level maintained at 5 cm. The amounts of supplied feces were 0 (control), 222, and 444 g/m2. While the addition of feces showed no immediate effects, nutrients in the surface water increased in the month following treatment. Nutrients increased to a greater degree in the treatments with more feces added. Simultaneously, the decomposition of rice straws was promoted, indicating that more nutrients would be made available over time. The rice showed high productivity in the period during which nutrient level was increased,when rice needs more nutrients for the tillering stage. Therefore, the wintering waterfowl’s feces could be associated with increased productivity during the growing season of rice through promoting nutrient supply and rapid decomposition of rice residue.
Abstract

While the addition of feces showed no immediate effects, nutrients in the surface water increased in the month following treatment. Nutrients increased to a greater degree in the treatments with more feces added. Simultaneously, the decomposition of rice straws was promoted, indicating that more nutrients would be made available over time. The rice showed high productivity in the period during which nutrient level was increased,when rice needs more nutrients for the tillering stage. Therefore, the wintering waterfowl’s feces could be associated with increased productivity during the growing season of rice through promoting nutrient supply and rapid decomposition of rice residue.
