9th International Drainage Symposium held jointly with CIGR and CSBE/SCGAB Proceedings, 13-16 June 2010, Québec City Convention Centre, Quebec City, Canada, 2010
Taking five drainage reuse sites in Yinbei irrigation districts, Ningxia for example, this paper analyzed the chemical characteristics of drainage water in ditches, saline-alkaline hazard and its impact of drainage reuse on soil. The result showed that the hydro-chemical type of drainage water is CNa at Nuanquan farm and ClNa at other four pilots ...

Horizontal distribution of phosphorus in soils of irrigation ditches
Global Journal of Pure and Applied Sciences, 2012The cultivation of vegetable crops during the dry season is an age-long practice by peasant farmers in northern Nigeria. The water for the irrigation of the plots is supplied by shallow streams, or ponds and wells dug along the banks of the streams. Phosphorus is an important plant nutrient.

Greenhouse gas emissions from drainage ditches and irrigation canals
Drainage ditches and irrigation canals are widespread across the globe, and have a high potential to emit greenhouse gases (GHG) to the atmosphere, contributing to climate change. Often located in agricultural or urban areas, ditches may receive high inputs of organic matter and nutrients, thereby stimulating GHG production.Teresa Silverthorn +2 more

Sources, fate and influencing factors of nitrate in farmland drainage ditches of the irrigation area
Journal of Environmental ManagementGlobal irrigation areas face the contradictory challenges of controlling nitrate inputs and ensuring food-safe production. To prevent and control nitrate pollution in irrigation areas, the study using the Yellow River basin (Ningxia section) of China as a case study, employed nitrogen and oxygen dual isotope tracing and extensive field investigations ...

Many scholars and students of the West refer to "Western water law" as if it were a monolithic entity predestined to triumph over all other possible alternatives.1 The common assumption used to be that once one gets past the 100th Meridian and into semiarid and arid climates, prior appropriation is the law of the land, that it was always so since white
