abstractbackground and objectives: in most saline and non-saline soils, nitrogen is the most restrictive nutrient for plant growth. in saline soils, interactive effects of salinity and soil fertility is very important from optimum production. nutrient imbalance is one of the problems with saline soils. in these circumstances, the fertilizer application may to increase osmotic effect of salt, th...

The formation of an anisotropic landscape is influenced by natural and/or human 2 processes, which can then be inferred on the basis of geometric indices. In this 3 study, two minimal bounding rectangles in consideration of the principles of 4 mechanics (i.e. minimal width bounding (MWB) box and moment bounding 5 (MB) box) were introduced. Based on these boxes, four novel shape indices, 6 namel...

Soil Salinity has been a large problem in arid and semi arid regions. Preparation of such maps is useful for Natural resource managers. Old methods of preparing such maps require a lot of time and cost. Multi-spectral remotely sensed dates due to the broad vision and repeating of these imageries is suitable for provide saline soil maps. This investigation is conducted to provide saline soil map...

<p>Salinity is a common problem of abiotic stress in the world. Salinity causes yield loss cultivated crops, such as maize. The maize exposed to salinity can be increased with application some beneficial microorganisms. Three isolates halotolerant bacteria from saline fields potentially used biostimulants (plant growth-promoting rhizobacteria). A field experiment study effect on growth an...

A field experiment was carried out to study the changes of soil bacteria, fungi and actinomycetes in saline-sodic soils for different numbers of cultivated years under drip irrigation. The drip irrigation had substantial effects on levels of bacteria, fungi and actinomycetes. With increased number of cultivated years under drip irrigation, the soil biological properties were greatly improved. A...

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...

Conventional water resources of good quality are scarce especially in arid and semiarid regions. The salinization of soils and water places is a substantial constraint of crop productivity. The mixed application of fresh water along with seawater is becoming a common practice by the farmers near sea sides in the developing countries. Seawaters contain beneficial nutrients that can be useful for...

Remediation of the petroleum contaminated soil is essential to maintain the sustainable development of soil ecosystem. Bioremediation using microorganisms and plants is a promising method for the degradation of crude oil contaminants. The effects of different remediation treatments, including nitrogen addition, Suaeda salsa planting, and arbuscular mycorrhiza (AM) fungi inoculation individually...
