Nitrate leaching is a common problem in frequently fertilized agricultural crops in Southern New Mexico. The objectives of this study were to estimate the leaching depths, irrigation and plant uptake efficiencies for onion (Allium cepa L.), chile (Capsicum annuum), and cotton (Gossypium spp.)...

Irrigation efficiency, as a complex and useful measure of irrigation performance, is in a vulnerable scientific position. Knowledge gaps feed through to naïve views of a sector held to be highly inefficient, ‘wasting’ freshwater which could be allocated to other purposes. Confusions and...

Good management of water in agriculture is essential in semiarid areas, as irrigation is the main user of a scarce resource. The present paper analyses the water use and the quality of irrigation in LASESA (LD), a mature sprinkler irrigation district of the Ebro valley, NE Spain, during the...

Inappropriate soil, water and fertilizer management in irrigated agriculture can result in environmental problems, including groundwater pollution with nitrates. Furrow irrigation is widely used around the world and is considered as a major source of nitrate leaching. Improved soil, water and...

Recent research suggests that regional hydrologic and economic implications should be considered before adopting policies encouraging efficient irrigation technology. Investigating regional effects of irrigation efficiency investments relies on predicting how farmers will adopt irrigation...
