Management of large volumes (60,000 ha-m) of co-production water associated with coal bed natural gas (CBNG) water extraction is a potential concern in the Powder River Basin (PRB) of Wyoming and Montana due to elevated water salinity and sodicity levels. Land application of saline-sodic CBNG water is a common water management method being practiced in the PRB, which can result in deterioration...

Salinization is the accumulation of water-soluble salts in the soil solum or regolith to a level that impacts on agricultural production, environmental health, and economic welfare. Salt-affected soils occur in more than 100 countries of the world with a variety of extents, nature, and properties. No climatic zone in the world is free from salinization, although the general perception is focuse...

Soil fertility is an important factor for plant growth and has a global impact on both developed developing countries. The present investigation was carried out soil status of farm in ADAC&RI, Trichy which comes under the Cauvery Delta Zone Tamil Nadu. pH value indicates that ADAC&RI soils are very strongly alkaline nature. rating electrical conductivity normal with values ranging from ...

Treating carrot (Daucus carota L.) discs with ice-cold NaCl solutions for 30 minutes caused three effects that appear to be functionally related: the exchange of tissue Ca(2+) and Mg(2+) for Na(+), the release of protein, and the suppression of active uptake of glucose and orthophosphate. Cyclosis continued apparently unabated after treatment with NaCl at concentrations of up to 0.25 m, so the ...

Assessing the ability of soil microorganisms to dissolute poorly soluble native calcite to supply Ca2+ is a new area to be explored in reclaiming sodic soils by supplying adequate Ca2+ and reducing the recurrent sodicity. Hence, the present study aimed to isolate a calcite dissolving bacteria (CDB) from calcareous sodic soils and to understand the mechanism of calcite dissolution. Of the 33 CDB...

Reclamation of salt-affected soil has been identified by the FAO as being critical to meet needs increase agricultural productivity. This paper reviews commonly used reclamation methods for soils, and provides identifiers an effective practice soil. There are widely reduce salinity sodicity including salt leaching, addition amendments, revegetation using halophytes scrapping. Not all techniques...
