Integrated Nitrogen Management in Irrigated Rice,er cultivation. The adoption of modern varieties, increased irrigation facilities, and more fertilizer use have been credited for the yield increases. An estimated 24% of the increase in Asian rice production from 1965 to 1980 was attributed to use of fertilizer, mainly N (Barker .., 1985).

Molecular Dynamics of Slow Viscous Flowsl moisture may uncouple low N supply from N limitation (Chapin .., 1986). In addition, the nonuniform rooting distribution of trees and the presence of forest floors add spatial complexities to forest N cycles that make it more difficult to estimate N availability in forests than in agroecosystems.
