Soil salinity is an increasingly serious problem worldwide that reduces agricultural output potential. Selected beneficial soil bacteria can promote plant growth and augment tolerance to biotic and abiotic stresses. Bacillus subtilis strain GB03 has been shown to confer growth promotion and abiotic stress tolerance in the model plant Arabidopsis thaliana. Here we examined the effect of this ben...

The application of organic amendments can be an appropriate solution to reclaim and improve physical propertiesof saline-sodic soils. In this research, an experiment was performed under greenhouse conditions to study the effect ofamendments to the physical properties of loamy saline-sodic soil. The five treatments were control (withoutamendment), municipal solid waste compost (MC), vermicompost...

abstract nowadays, environmental pollution by heavy metals is one of the most serious threats of the world which needs effective remediation actions. the aim of this study was to investigate the potential use of atriplex [atriplex verucifera], salicornia [salicornia europaea] and chenopodium album in simultaneous uptake and accumulation of na and cd or pb in two calcareous soils with different ...

A laboratory microcosm experiment was conducted to determine whether the earthworm Eisenia fetida could survive in a saline soil from a field site in North China, and an experiment using response surface methodology was conducted at that field site to quantify the effects of E. fetida and green waste compost (GWC) on the salt content of the soil. The microcosm results showed that E. fetida surv...

This study investigated the influence of Trichoderma asperellum on active oxygen production in maize seedlings under saline-alkaline stress conditions. Two maize cultivars were tested: 'Jiangyu 417' ('JY417'), which can tolerate saline-alkaline stress; and, 'Xianyu 335' ('XY335'), which is sensitive to saline-alkaline stress. The seedlings were grown on natural saline-alkaline soil (pH 9.30) in...

Soil salinity is one of the most damaging environmental problems worldwide, especially in arid and semi-arid regions. An integrated approach using remote sensing in addition to various statistical methods has shown success for developing soil salinity prediction models. The aim of this study was to develop statistical regression models based on remotely sensed indicators to predict and map spat...

Soil compaction is an important physical limiting factor for the root growth and plant emergence and is one of the major causes for reduced crop yield worldwide. The objective of this study was to generate 2D/3D soil compaction maps for different depth layers of the soil. To do so, a soil penetrometer was designed, which was mounted on the three-point hitch of an agricultural tractor, consistin...
