To increase the fertility of neutral salt pans and improve their physico-chemical properties under intensive irrigation, it is necessary to apply a set measures. Reclamation saline soils should be aimed at reducing content exchangeable sodium in absorbing complex, improving chemical water-physical creating highly fertile root-inhabited soil layer. When developing flats irrigation conditions, bo...

Drought and salinity are major factors limiting agriculture in many regions in the world, and their importance is predicted to even increase in the near future in parallel with the ongoing global warming and climate changes. Soil and rhizosphere microbes are potential resources for counteracting such abiotic stresses in plants. The knowledge on the roles of root microorganisms in retaining soil...

A long-term experiment (2013 to 2017) of treated sewage effluent (TSE) levels via fertigation in a humid tropical region was installed Jaboticabal, state São Paulo, Southeast Brazil, evaluate the impact TSE on soil fertility and potential for salinization heavy metal contamination an Oxisol. The area cultivated with Urochloa brizantha under application four at irrigation depth (0, 11, 60, 100% ...

Tongyu County in Northeast China is highly prone to land degradation due to its fragile physical settings characterized by a flat topography, a semi-arid climate, and a shallow groundwater table. This study aims to determine the causes of land degradation through detecting the long-term trend of land cover changes. Degraded lands were mapped from satellite images recorded in 1992 and 2002. Thes...

Salinity is a major abiotic stress limiting growth and productivity of plants in many areas of the world due to increasing use of poor quality of water for irrigation and soil salinization. Plant adaptation or tolerance to salinity stress involves complex physiological traits, metabolic pathways, and molecular or gene networks. A comprehensive understanding on how plants respond to salinity str...

Land salinization is widespread in countries of the arid zone, including Aral Sea basin, where 4 million hectares irrigated land are salt-affected, causing high economic losses. Current saline soil reclamation practices include leaching and deep drainage to remove excess water outside zone. Growing pressure on limited resources makes this practice ineffective. An alternative biological methods ...

soil is one of the most important natural resources covering a large area of the land surface. soil plays a vital role in biosphere processes, such as energy balance, hydrology, biochemistry, and biological productivity. it supports plants that supply foods, fibers, drugs, and some other human needs. conversely, desert regions include about one third of earth lands and these regions have increa...

Groundwater is an important ecological water source in arid areas. depth (GWD) indicator that affects vegetation growth and soil salinization. Clarifying the coupling relationship between vegetation, groundwater, areas beneficial to prevention of environmental problems such as desertification Existing studies lack research on water–soil–vegetation typical areas, especially shallow groundwater I...
