TL;DR: Subsurface drainage is an effective tool to combat this twin problem of waterlogging and salinity and thus to protect capital investment in irrigated agriculture and increase its sustainability in India as discussed by the authors.

TL;DR: In this paper, the authors reviewed and summarized findings from more than 30 North American studies of pesticide transport into subsurface agricultural drains and found that the presence of a subsuran-surface drainage system generally increases the volume of infiltration and consequently decreases the volumes of surface runoff water and sediment compared with similar soils.
Abstract: This report reviews and summarizes findings from more than 30 North American studies of pesticide transport into subsurface agricultural drains. Background information about subsurface drainage use and its importance for crop production and environmental protection is also presented. The presence of a subsurface drainage system generally increases the volume of infiltration and consequently decreases the volume of surface runoff water and sediment compared with similar soils where subsurface drainage systems are not installed. Therefore, in general, the presence of subsurface drainage decreases surface runoff losses of sorbed compounds such as pesticides, both because of lower runoff volumes and often also because of lower concentrations in the runoff resulting from the delayed initiation of runoff. Pesticide concentrations and mass losses are usually much lower in subsurface drainage than in surface runoff, often by an order of magnitude. In the medium- and fine-textured soils where subsurface drainage i...

TL;DR: In this paper, the authors report results of field studies to determine the effectiveness of drainage water management (DWM) on conserving drainage water and reducing losses of nitrogen (N) to surface waters.
Abstract: T his article introduces a series of papers that report results of field studies to determine the effectiveness of drainage water management (DWM) on conserving drainage water and reducing losses of nitrogen (N) to surface waters. The series is focused on the performance of the DWM (also called controlled drainage [CD]) practice in the US Midwest, where N leached from millions of acres of cropland contributes to surface water quality problems on both local and national scales. Results of these new studies are consistent with those from previous research reported in the literature that DWM can be used to reduce N losses (primarily in the nitrate nitrogen [NO3-N] form) from subsurface drained fields. The measured impact varied over a wide range (18% to more than 75% reduction in N loss to surface waters), depending on drainage system design, location, soil, and site conditions. Crop yields were increased by DWM on some sites and not on others, with the year-to-year impacts of DWM on yields dependent on weather conditions, as well as the above factors. Papers reporting advances in the development of datasets and models to predict the impact of drainage intensity and DWM on hydrology and water quality at watershed and…

TL;DR: In this article, a headwater watershed (4 km2) in central Ohio, USA and all functioning tile were monitored from 2005 to 2010 in order to characterize the magnitude and frequency of flows, quantify the role and seasonal contributions of tile drainage to watershed hydrology, and relate tile drainage with precipitation and antecedent conditions.
