Modeling the impact of nitrogen fertilizer application and tile drain configuration on nitrate leaching using SWAT

A coupled modeling approach to evaluate nitrogen retention within the Shanmei Reservoir watershed, China

“…It has become an effective means of predicting long-term impacts of land management measures on water, sediment, and agricultural nutrient loss in large, complex watersheds and has been widely applied for dealing with quantity and quality issues including NPS pollution (Ullrich and Volk, 2009;Moriasi et al, 2013;Chen et al, 2014). It has also been applied to the Shanmei Reservoir watershed Yang et al, 2013).…”

Assessing the impacts of sustainable agricultural practices for water quality improvements in the Vouga catchment (Portugal) using the SWAT model

“…In this sense, it can also be used to establish optimized agricultural management (e.g. fertilization, tillage, irrigation) (Holvoet et al, 2007;Ullrich and Volk, 2009;Lam et al, 2010;Kaini et al, 2012;Moriasi et al, 2013;Bouraoui and Grizzetti, 2014;Aouissi et al, 2014;Chen et al, 2014;Pongpetch et al, 2015).…”

Water use and soil nitrate nitrogen changes under supplemental irrigation with nitrogen application rate in wheat field

“…Several studies showed that NO 3 N losses decreased with reductions in fertiliser application rates (Moriasi et al, 2013;Randall and Vetsch, 2003). For example, NO 3 N losses were decreased by 67% when the N application rate decreased by 50% (Moriasi et al, 2013). Yang et al (2014) reported that nitrate leaching mainly occurred after irrigation, and that NO 3 N leaching increased as more irrigation water was applied (Gheysari et al, 2009;Vázquez et al, 2006).…”
