Soil correction is one of the ways in agriculture lands development. The sodic ion alongside salin vocalizes the salin-sodic soil and cause divulge in plants growth. So necessary coure of action for the Soil correction by physical and chemical ways such as usage of calsium on the leaching is inevitable. In this study, area soils are digged from deep profiles of 0-20, 20-40, 40-60, 60-80 and 80-...

road network (rn) can affect patterns and distribution of land uses and covers. road network expansion has both direct and indirect impacts on land uses and covers changes. agricultural land conversions (alcs) are especially known as one of the main important types of land use changes. the purpose of this paper, in addition to estimation of the direct impact of rn expansion on alcs, is to evalu...

Salt tolerance mechanism of an extreme halophyte Salvadora persica was assessed by analyzing growth, nutrient uptake, anatomical modifications and alterations in levels of some organic metabolites in seedlings imposed to various levels of salinity (0, 250, 500, and 750 mM NaCl) under hydroponic culture condition. After 21 days of salt treatment, plant height, leaf area, and shoot biomass decrea...

Despite general effect of salicylic-acid (SA) in improving plant growth andproductivity in saline conditions, there have not been unanimity about the bestconcentration. In this 2-yr field study the effect of different SA concentrations(0, 0.5, 1.0, 1.5 and 2.0 mM) was examined on growth, grain yield and yieldcomponents of barley under two non-saline (2 dS m-1) and saline (12 dS m-1)conditions. ...

For many of Utah’s rural communities, the problem of either growth or decline has been compounded by dependency on public lands and the changing perceptions by the general public of how these lands should be used. Utah communities whose economies have revolved around farming, ranching, and extraction of natural resources have depended upon access to and use of public lands, but use of these lan...

The Baltic Sea, a large estuarine sea in northern Europe, has for many decades displayed obvious signs of anthropogenic eutrophication. This study relates long-term trends in total phosphorus (TP) loadings and TP concentrations in surface waters regarding five major sub-basins of the Baltic Sea; the Bothnian Bay, the Bothnian Sea, the Baltic Proper, the Gulf of Finland and the Gulf of Riga. The...

Salinity of soil is a major abiotic stress limiting the crop production and growth of safflower. To mitigate stress, the effects of penconazole (PEN) on the growth of safflower were studied to understand the underlying mechanisms of salt tolerance. PEN, a triazole derivative, which has both fungicidal and plant growth regulator properties, protects plants from several types of abiotic stresses....
