Polymorphum gilvum SL003B-26A1(T) is the type strain of a novel species in the recently published novel genus Polymorphum isolated from saline soil contaminated with crude oil. It is capable of using crude oil as the sole carbon and energy source and can adapt to saline soil at a temperature of 45°C. The Polymorphum gilvum genome provides a genetic basis for understanding how the strain could d...

Soil and water resources can be severely degraded by salinity when total salt input exceeds output in irrigated agriculture. This study was conducted to examine partitioning of Ca2+, Na+, and Cl- between soil and soybean [Glycine max (L.) Merr.] plants under different irrigation regimes with both field and modeling assessments. In drip and sprinkler treatments, the irrigation water was salinize...

Salinity as well as drought are increasing problems in agriculture. Durum wheat (Triticum turgidum L. ssp. durum Desf.) is relatively salt sensitive compared with bread wheat (Triticum aestivum L.), and yields poorly on saline soil. Field studies indicate that roots of durum wheat do not proliferate as extensively as bread wheat in saline soil. In order to look for genetic diversity in root gro...

Salinity has plagued irrigated agriculture throughout history (Tanji, 1990), and soil salinization is an old–yet– new problem in arid regions. For example, there are approximately 100 million ha of salt–affected soils in China, accounting for one tenth of the total land area (Li, 2009). The development of effective salinity control practices requires an understanding of the causal relationship ...

Salt-affected arable land is distributed widely in China, especially the North China Plain. Crop residue management under appropriate tillage critical to improving salt-affected soil organic carbon and reducing footprint. This study conducted four-year field experiments including two treatments (residue incorporated into with plough (CT+); mulching no-till (NT+)) sites (non-saline soil); footpr...

The analysis and forecast of the distribution and dynamics of soil organic matter (SOM) content is an essential requirement for sustainable land management, especially in Western Jilin, where the saline-alkalized land increased at a very fast rate per year and is in desperate need of improving soil. Compared to conventional analytical methods, hyperspectral remote sensing is faster, cheaper, no...
