Irrigation management is based upon delivery of water to a crop in the correct amount and time, and the crop’s water need is determined by calculating evapotranspiration (ET) using weather data. In 1994, an ET-network was established in the Texas High Plains to manage irrigation on a regional scale. Though producers used the ET-network, by 2010 public access was discontinued. Why did producers ...

The impact of climate change on the ecosystem of the Mediterranean Sea basin will be manifested mainly by a significant reduction in water resources, because of rising temperatures and lower rainfall despite the increase in heavy precipitation events. Water is a fundamental resource for the metabolic activities of plants in agriculture. Unfortunately this resource is available in limited quanti...

Increasing of water consumption and demand for irrigation water in agriculture has led to an increase in reuse of treated, or even raw, municipal and industrial wastewater in many countries. Heavy metals (HMs) in these unconventional waters are one of the sources of pollution of water, soil and plant. HM toxicity in plants may eventually cause disturbances in plant growth. Accumulation of HMs i...
