Objective: Soil salinity is one of the major worldwide environmental constraints affecting agricultural production in arid and semiarid regions. Lack of proper management of water and soil resources lead to increase soil salinity and reduce soil fertility. On the other hand, it seems simple and cheap method of measuring soil salinity is necessary. The aim of this study was to determine the rela...

BACKGROUND Although the effect of water level on germination in soil seed banks has been documented in many ecosystems, the mechanism is not fully understood, and to date no empirical studies on this subject exist. Further, no work has been done on the effect of water level on seed banks of drying and saline-alkaline wetlands in alpine areas on the Tibetan Plateau. METHODOLOGY We examined the...

boron (b) is an important plant essential micronutrient whose availability is influenced by many soil factors. adsorption–desorption processes play a major role in governing the solubility of boron in soil solution and, consequently, its availability to growing plants. to assess the effect of sodium adsorption ratio (sar) on availability of b, adsorption of b was investigated in a sampled calca...

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...

Fresh water source scarcity in arid and semiarid area is limitation factor for saline-sodic soil reclamation. The reusing of agricultural drainage and industrial wastewater are preferred strategies for combating with this concern. The objective of current study was evaluation in application of industrial sugar manufacture wastewater due to high soluble organic compounds in saline-sodic and sodi...

Soil physicochemical properties are the main driving factors affecting stability and diversity of soil microbial community. The impacts saline–alkali situation associated degradation need to be understood reversed as communities increasingly affected by saline–alkaline soil. However, differences between salinization alkalization their impact on microbiota have been overlooked. object this study...
