Soil salinity is one of the important factors which can influence the growth anddistribution of plant species. Saline and alkaline rangelands of Golestan Province, Iran withlow-deep underground water level are considered as a halophyte plant species growing area.Attempts have been made to determine soil salinity and its relationship with Frankenia hirsutaL. In order to determine the Electrical ...

one of the main strategy for controlling salt-affected soils is to implement proper tillage method. a field experiments was conducted to determine the effect of different tillage methods on salt distribution and wheat yield in saline-sodic soil. the experiment was laid out according to randomized complete block design with three replications. treatments were studied in the experiment including ...

in order to investigate the effects of saline waters on some soil characteristics, this experiment was conducted with three irrigation water salinity treatments contains 1.7-3.4, 8-9 and 11-12.5 dsm-1 (low, medium and high salinity) and two irrigation water managements with four replications in a wheat-fallow-sugar beet-safflower rotation. results show that in (1) irrigation management with low...

the study of the relationships of the plant species with the soil in a salty ecosystem would play a significant role in the ecologic programming and management of these inhabitants. the saline and alkaline rangelands of the golestan province are areas that contain salty soil with high underground crusts. the areas are covered by halophyte plants such as frankenia hirsuta. this species is a pere...

Nowadays, applying soil amendments is one of the most important ways to cope with water shortages and improve soil physical properties. In this regard, a greenhouse experiment was conducted to study the effect of different levels of irrigation water and wheat straw biochar on physical and chemical properties of a sandy loam soil, after harvesting faba bean. The experiment was performed with 5 b...

The temporal-spatial coincidence of saline deposits with rifting and alkaline magmatism has now become a commonly accepted fact. The congruency of these three phenomena implies logically, their trilateral genetic interrelation. The conventional concept for the formation of saline deposits, i.e an "evaporation process" can not be properly applied to giant saline deposits. The proposed "Volc...

Microsprinkler irrigation is a potential method to alleviate soil salinization. After conducting a homogeneous, highly saline, clayey, and coastal soil from the Bohai Gulf in northern China in a column experiment, the results show that the depth of the wetting front increased as the water amount applied increased, low-salinity and low-SAR enlarged after irrigation and water redistribution, and ...

The objectives of this study were to investigate the degree of spatial variability and variance structure of salinization parameters using classical and geostatistical method in Songnen Plain of China, which is one of largest saline-sodic areas in the World, and to analyze the relationship between salinization parameters, including soil salinity content (SC), electrical conductivity (EC), sodiu...

The research aimed to determine the effects of Si application on photosynthetic characteristics of maize on saline-alkaline soil, including photosynthetic rate (P n ), stomatal conductance (g s ), transpiration rate (E), and intercellular CO2 concentration (C i ) of maize in the field with five levels (0, 45, 90, 150, and 225 kg · ha(-1)) of Si supplying. Experimental results showed that the va...
