Surface runoff from cropland frequently has high concentrations of nutrients and herbicides, particularly in the first few events after application. Grassed waterways can control erosion while transmitting this runoff offsite, but are generally ineffective in removing dissolved agrochemicals. In this study, we routed runoff from one tilled (0.67 ha) and one no-till watershed (0.79 ha) planted to corn (Zea mays L.) into parallel, 30-m-long grassed waterways. Two 46-cm-diam. filter socks filled…

Sorbent-amended compost filter socks in grassed waterways reduce nutrient losses in surface runoff from corn fields

Surface runoff from row-crop fields frequently has high concentrations of sediment, nutrients, and pesticides, particularly in the first few events after tillage and agrochemical application. Compost

Land drainage to support agricultural production can be traced back thousands of years to the ancient civilization of Mesopotamia along the banks of the Euphrates and Tigris. A ubiquitous drainage

Vegetative Buffer and Fly Ash Pad Surface Material System Application for Reducing Runoff, Sediment and Nutrient Losses from Livestock Manure Windrow Composting Facilities

Applying livestock manures to agricultural cropland continues to contribute significant levels of sediment and nutrient pollutants to streams and other water bodies. Vegetative buffers have been

Banded applications are highly effective in minimising herbicide migration from furrow-irrigated sugar cane.

Phosphorus losses from monitored fields with conservation practices in the Lake Erie Basin, USA

Assessment of the impact of Farm Bill eligible conservation practices on soluble P (SP) and total P (TP) losses from four fields that were monitored between 2004 and 2013 found that they can potentially attain TP water quality goals using these Farm Bill practices; however, additional strategies must be employed to meet these goals for SP.

Water Use and Treatment in Container-Grown Specialty Crop Production: A Review

This review focuses on multiple facets of water use, reuse, and runoff in nursery and greenhouse production including current and future regulations, typical water contaminants in production runoff and available remediation technologies, and minimizing water loss and runoff (both on-site and off-site).

Mulch-Derived Organic Carbon Stimulates High Denitrification Fluxes from Agricultural Ditch Sediments.

Results indicate DOC from overlying mulch additions to agricultural ditched significantly increase denitrification in intact cores and suggest that the addition of DOC sources in agricultural ditches may contribute a simple, low-cost option to reduce reactive N export and improve ecological outcomes within aquatic agroecosystems.

Effectiveness of Dichanthium annulatum in Watercourses for Reducing Sediment Delivery from Agricultural Watersheds

A field experiment was conducted to determine the efficacy of Dichantium annulatum grass filters in watercourses and to optimize the grass coverage in these watercourses. This experiment was

Efficacy of selected phosphorus sorbing materials (PSMs) to enhance the orthophosphate sorption capacity of filter socks

Agricultural phosphate (PO43−) is a major cause of water quality compliance failures. Filter socks (FS) are a sediment‐control method proven to be effective at removing sediment and sediment bound‐P.



Effectiveness of grassed waterways in reducing runoff and sediment delivery from agricultural watersheds.

A long-term landscape experiment performed in four watersheds indicated a high potential of GWWs for reducing runoff volume and velocity, sediments, and agrochemicals coming from agricultural watersheds.

The impact of conservation tillage on pesticide runoff into surface water: A review and analysis

The presence of detectable concentrations of pesticides in surface water has caused some concerns about possible effects on human health and aquatic biology. Herbicides are the class of pesticide

Tillage system, application rate, and extreme event effects on herbicide losses in surface runoff.

For all watersheds, 60 to 99% of herbicide loss was due to the five largest transport events during the 9-yr period, regardless of tillage practice, and concentrations of some herbicides may still be a concern.

Sediment and Chemical Load Reduction by Grass and Riparian Filters

Vegetated filter strips help reduce non-point source pollution from agricultural areas. Even though they are an accepted and highly promoted practice, little quantitative data exist on their

Modeling Hydrologic and Water Quality Responses to Grass Waterways

The impact of vegetation filter strips on runoff, sediment yield, and atrazine loss from a cultivated field was investigated using a physically based, distributed watershed model. The field to which

Effects of hydrodynamically rough grassed waterways on dissolved reactive phosphorus loads coming from agricultural watersheds.

It was found that the introduction of a relatively small grassed area has little effect on the DRP concentration in surface runoff from the total watershed, and such GWWs will thus reduce theDRP load analogously to the reduction in total surface runoff.

The Pesticide Content of Surface Water Draining from Agricultural Fields—A Review

The literature on pesticide losses in runoff waters from agricultural fields is reviewed. For the majority of commercial pesticides, total losses are 0.5%0 or less of the amounts applied, unless
