Assessment of Drought impact on Irrigated Agriculture in Lorestan Province
Agriculture in Lorestan Province is based on irrigated and rainfed agriculture, which uses two sources of surface water and groundwater. One of the most important natural hazards affecting the Lorestan Province agriculture is the occurrence of drought and its consequences. The main purpose of this study is to investigate the effects of drought on irrigated agriculture in this province. The data...
متن کاملControlling nitrate leaching in irrigated agriculture.
The impact of improved irrigation and nutrient practices on ground water quality was assessed at the Nebraska Management System Evaluation Area using ground water quality data collected from 16 depths at 31 strategically located multilevel samplers three times annually from 1991 to 1996. The site was sectioned into four 13.4-ha management fields: (i) a conventional furrow-irrigated corn (Zea ma...
متن کاملTowards Global Mapping of Irrigated Agriculture
We developed an irrigation mapping methodology that relies on remotely sensed inputs from MODerate Resolution Imaging Spectroradiometer (MODIS) instrument, globally extensive ancillary sources of gridded climate and agricultural data and on an advanced image classification algorithm. In the first step, we used climate-based indices of surface moisture status and a map of cultivated lands to pro...
متن کاملAssessment of Soil Health in Urban Agriculture: Soil Enzymes and Microbial Properties
Urban agriculture has been recently highlighted with the increased importance for recreation in modern society; however, soil quality and public health may not be guaranteed because of continuous exposure to various pollutants. The objective of this study was to evaluate the soil quality of urban agriculture by soil microbial assessments. Two independent variables, organic and inorganic fertili...
متن کاملSustainability of irrigated agriculture in the San Joaquin Valley, California.
The sustainability of irrigated agriculture in many arid and semiarid areas of the world is at risk because of a combination of several interrelated factors, including lack of fresh water, lack of drainage, the presence of high water tables, and salinization of soil and groundwater resources. Nowhere in the United States are these issues more apparent than in the San Joaquin Valley of Californi...
