Regional agricultural development projects based on water resource development have many potential impacts on social and natural environments. In this research, potential long-term environmental problems of the Southeastern Anatolian Project (GAP) related to water resources, land use, land degradation, agricultural pollution and demography are analyzed from a systems perspective. The analysis f...

Partial Least Squares Regression (PLSR) can integrate a great number of variables and overcome collinearity problems, a fact that makes it suitable for intensive agronomical practices such as land application. In the present study a PLSR model was developed to predict important management goals, including biomass production and nutrient recovery (i.e., nitrogen and phosphorus), associated with ...

Land use may be regarded as one of the most important factors affecting theenvironment with respect to human activities. So far, destroying the rangelands andchanging them into the waste lands and poor rangelands has been proposed as the mostsignificant variations of land use done by human beings. This paper has been conducted toevaluate the variations of vegetation percentage and land uses in ...

Agricultural crops take up water, but not salt, and evaporation from irrigated land does likewise. The result is increasing salt levels in soils. Just as cities cannot ignore urban wastewater collection and treatment, irrigating farmers and irrigation districts cannot ignore what to do with the salt in agricultural drainage water. Although salt management techniques can seem straightforward, th...

Salinity is one of the most severe abiotic stresses in one-half of all irrigated lands, causing negative effects on physiological, biochemical, and molecular responses in plants. Application of chemical fertilizers, particularly phosphorus (P) fertilizers, may reduce harmful effects of salinity. In this study, an investigation was performed on the effects of exogenous application of different l...

Upper Blue Nile Basin, Ethiopia. This study was conducted at the Koga Irrigation Scheme in upper basin (Ethiopia) to investigate influence of irrigation activity on groundwater system. Representative samples six shallow wells irrigated fields and four adjacent non-irrigated (rain-fed agricultural lands) were selected. Dipmeter hand GPS (GARMIN 60) used for monitoring water table depth fixing lo...

Definitions and forms of salinity All natural waters contain soluble salts. The concentration of the salts determines whether the water is of high quality (drinkable or usable for irrigation without need for special precautions) or of low quality (brackish or saline). Water in the soil also contains soluble salts (sometimes called free or nonattached salts). The amount of salts in the root zone...
