- Water and Nitrogen Transport in Wheat and Maize: Impacts of Irrigation, Fertilization, and Soil Management (2025) · Agriculture · cited 9× · doi
The paper identifies a gap in the current understanding of how irrigation, nitrogen application, and soil management regulate water–nitrogen migration and transformation processes. It highlights the need for integrated management practices that consider the interactions between water and nitrogen. The paper notes that the effectiveness of these measures is highly context-dependent and influenced by a combination of factors.
