BACKGROUND AND AIMS In China, excessive fertilization has resulted in phosphorus (P) accumulation in most greenhouse soils. Intercropping can improve the efficiency of nutrient utilization in crop production. In this study, pot experiments were performed to investigate the effects of intercropping with potato onion (Allium cepa L. var. aggregatum G. Don) on tomato (Solanum lycopersicum L.) seed...

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...

Soil salinization caused by sea level rise threatens coastal agricultural soils and geochemically important wetlands worldwide. The aim of this review is to outline expected changes in soil biological activity discussing the combined effects salt stress flooding on plants productivity microbial communities, which determine consequences fluxes C, N P. Finally, it outlines repercussions greenhous...

Abstract Background Salinization damages the health of soil systems and reduces crop yields. Responses microbial communities to salinized soils their functional maintenance under high salt stress are valuable scientific problems. Meanwhile, community in plateau environment is less understood. Here, we applied metagenomics technology reveal structure function microorganisms Tibetan Plateau. Resu...

Soil salinization causes negative effects on plant productivity and poses an increasingly serious threat to the sustainability of agriculture. Improving salt and drought tolerance is one of the most diffi cult tasks for cereal breeders. A breeding program using somaclonal variation through biotechnological techniques has been used in rice to improve drought and salinity tolerance for increasing...

Wetlands, and specially salt marshes, represent the final stage of the filling of depressions, embayments, levelling of marine delta plains and other depositional environments. Due to their origin, they are porous media, with high permeability, permanently flooded, or with very shallow oscillating groundwater table. They are rich in wildlife and among the most primary producers environments in ...

With the implementation of water-conservation projects in Hetao Irrigation District (HID), great changes have taken place ecohydrological process. A cultivated land–wasteland–lake system upper Yellow River Basin (YRB) was chosen to study soil salt and water transport process with Hydrus-1D model. The model parameters were calibrated validated by measuring data. Measured values good agreement si...

Soil and groundwater salinization are major problems for irrigated agriculture in many arid and semiarid areas of the world. Studies addressing such problems require accurate estimation of salt loadings from irrigated areas through the vadose zone to underlying groundwater. We studied Cl transport in the vadose zone at 45 locations in a field in the San Joaquin Valley, California, through a com...

Soil salinization is a serious resource and ecological problem globally. The Weigan River–Kuqa River Delta Oasis key region in the arid semi-arid regions of China with prominent soil salinization. saline soils oasis are widely distributed over large area, causing great harm to agricultural development environment. Remote sensing monitoring can provide reference method for management regional We...
