salinization and alkalization are the most problem in the arid and semi-arid regions, where precipitation is low than evapotranspiration. under such a climatic condition, soluble salts are accumulated in the soil, which cause lessening of the soil productivity and fertility. so, the identification of the salt affected areas is essential for sustainable soil management. the specific objective of...

population growth rating, high food demand, and land resource challenges have led to more serious studies of production factors especially the scarce water and soil resources. one of the most basic data items in land resources is the soil map. therefore, in the process of the present research for preparing soil maps of some soil quality indices at the faculty of agriculture experimental field (...

Freshwater resources are scarce in desert regions. Highly saline groundwater of different salinity is being used to drip irrigate the Taklimakan Desert Highway Shelterbelt with a double-branch-pipe system controlling the irrigation cycles. In this study, to evaluate the dynamics of soil moisture and salinity under the current irrigation system, soil samples were collected to a 2-m depth in the ...

Soils lie at the interface between the atmosphere and the subsurface and are a key component that control ecosystem services, food production, and many other processes at the Earth's surface. There is a long-established convention for identifying and mapping soils by texture. These readily available, georeferenced soil maps and databases are used widely in environmental sciences. Here, we show ...
