ENHANCING FURROW IRRIGATION PERFORMANCE AND WATER PRODUCTIVITY THROUGH BETTER DESIGN AND WATER MANAGEMENT IN A CRACKED SOIL

The Iraqi Journal of Agricultural science, 2020
Furrow irrigation is widely used because of its low cost and energy requirement, but less efficient compared with the pressurized irrigation systems. Management of water resources in Vertisols is more problematic compared to other soil groups.

Sediment and Phosphorus Transport in Irrigation Furrows [PDF]

Journal of Environmental Quality, 2006
ABSTRACTSediment and phosphorus (P) in agricultural runoff can impair water quality in streams, lakes, and rivers. We studied the factors affecting P transfer and transport in irrigated furrows in six freshly tilled fallow fields, 110 to 180 m long with 0.007 to 0.012 m m−1 slopes without the interference of raindrops or sheet flow that occur during ...

Development of a furrow irrigation method [PDF]

E3S Web of Conferences, 2020
The article describes the technology of laying a film covering with a specially selected perforation of holes on the laid groove with fastening the edges of the covering along its entire length. Calculations of the irrigation rate are given, which must be strictly observed for economical water use when irrigating along furrows.

Phosphorus Losses in Furrow Irrigation Runoff [PDF]

Journal of Environmental Quality, 2001
ABSTRACTPhosphorus (P) often limits the eutrophication of streams, rivers, and lakes receiving surface runoff. We evaluated the relationships among selected soil P availability indices and runoff P fractions where manure, whey, or commercial fertilizer applications had previously established a range of soil P availabilities on a Portneuf silt loam ...
