As salt-affected soils (SAS) are widespread in Hungary, several classification schemes have been proposed for them during the last centuries. These soils are inherently related to soil salinity/sodicity/alkalinity and the consequential hydrophysical properties of the soil; therefore, they present severe abiotic stress for plants and animals. Based on the approach of the assessment of the soil, ...

Plants, being sessile in nature, have developed mechanisms to cope with high salt concentrations in the soil. In this study, the effects of NaCl (50-200 mM) on expression of high-affinity potassium transporters (HKTs), antioxidant enzymes and their isozyme profiles were investigated in two contrasting bread wheat (Triticum aestivum L.) genotypes viz., HD2329 (salt-sensitive) and Kharchia65 (sal...

F. elatior, Puccinellia distans, Lotus strictus have been tested at 4 different water table depths which grow under natural conditions in salt-affected soils of arid and semi-arid regions. The trial was carried out for 3 years with split plots test design randomized blocks. salt concentration the groundwater where irrigation has made between 3.1-4.4 dS m-1. effect on dry grass yields cultivars ...

The effects of salinity on soil organic carbon (SOC) and its labile fractions including microbial biomass carbon (MBC) and easily oxidation organic carbon (EOC), basal soil respiration, and soil nematode community in the Fluvents, an oasis in an arid region of northwestern China were investigated. Five sites were selected which had a salinity gradient with different groundwater table from 1.0 m...

In 2010 and 2011, pot experiments were conducted at Niono Agronomic Research station to determine soil alkalinity/salinity effects on seed germination and seedling growth of vegetable crops. Three types of soil types with physical sign of salt effects were used for these experiments: salt affected black soil, salt affected white soil and soil presenting no physical sign of salinization. The tes...

Soil salinity / alkalinity development is one of the major land degradation problem affecting sustainable agricultural productivity in irrigated areas of arid and semi arid regions of the world. The characterization and mapping of salt affected soils is difficult as the salt concentration may vary substantially over short distances. Various broadband multi-spectral satellite data and spectral i...

Salinity is a major abiotic stress that reduces crop productivity in arid and semiarid soils. About 25% of the country's arable land is affected by different levels of salt. A considerable part of this land is under wheat cultivation each year as the country's most important crop. ACC deaminase producing bacteria increase plant resistance to stress condition by reducing stress ethylene in a var...
