Enhancement of water and nitrogen use efficiency simultaneously may provide advantages
over optimization of water and nitrogen inputs separately. In addition, water is the driver of …

Nitrate leaching (NL) is an important N loss process in irrigated agriculture that imposes a
cost on the farmer and the environment. A meta-analysis of published experimental results …

Introducing cover crops in irrigated areas may play a relevant role in providing ecosystem
services such as erosion control, clean water and mitigation of soil degradation. Our …

This study analyzes the effects of irrigation modernization on water conservation, using the
Riegos del Alto Aragón (RAA) irrigation project (NE Spain, 123354ha) as a case study. A …

Using cover crops (CC) in semiarid irrigated areas is often limited by low nutrient and water-
use efficiency. This work was conducted over 3.5 years to determine the effect on NO3 …

Dissimilatory nitrate reduction to ammonium (DNRA) is important for nitrogen retention in
ecosystems and is in competition with denitrification. However, denitrification tends to …

There is concern about environmental impacts of cropping in catchments of Australia's Great
Barrier Reef, especially losses of nitrogen (N) from cropping systems. Sugarcane production …

Worldwide, Mediterranean cropping systems face the complex challenge of producing
enough high-quality food while preserving the quantity and quality of scarce water for …

Maintain high agriculture production levels while reducing environmental impacts is of
primordial importance in intensive irrigated areas. Adequate management of water and …

The salinization of freshwaters is a global water quality problem that leads to the biological
degradation of aquatic ecosystems. However, little is known about the spatial extent of …
