Abstract:

The results of research on the characteristics of soft clay soils distributed in some provinces of the Mekong Delta show that most of the soils are contaminated with easily soluble salts, containing organic matter, pH < 7. Sandy clay, clay in An Giang, and clay mud in Tien Giang are less acidic, not salty, and contamination of salts in the form of sulfate- chloride. Clay mud in Hau Giang is less acidic, less salt, and contamination of salts in the form of chloride-sulfate. Clay mud in Bac Lieu and Ca Mau are lots of salty soil, contaminated with chloride of salts. Peat soil in Kien Giang is

Abstract:

The paper concerns the problems of making healthy salinized soils of pre-Caspian lowland in Azerbaijan Republic by chemical melioration. As a result of carried out experiments it has been determined that washing soils by water results in gyps leaching in the soils and formation alkaline salts. It leads to soda formation, salinization of soils and alkalıne formation. Though washing by drywall does not result in new formation of precipitated gyps, its application as meliorant presents formation of alkaline salts and salinization of solis. Gypsing of soils significantly optimizes leaching of salt

Applications of sulfate and carbonate salts have been shown to improve the solubility of phosphorus (P) in model calcareous soils. It is unclear how these treatments will influence P solubility in real soils.

We hypothesized that the application of carbonate or sulfate salts in a fertilizer band could enhance the solubility of P in Manitoba soils.

ABSTRACT NH4 + inhibition kinetics for CH4 oxidation were examined at near-atmospheric CH4 concentrations in three upland forest soils. Whether NH4 +-independent salt effects could be neutralized by adding nonammoniacal salts to control samples in lieu of deionized water was also investigated. Because the levels of exchangeable endogenous NH4 + were very low in the three soils, desorption of endogenous NH4 +was not a significant factor in this study. TheKm(app) values for water-treated controls were 9.8, 22, and 57 nM for temperate pine, temperate hardwood, and birch taiga soils, respectively.

The response of soils to non-ammonium salts has previously raised questions about the mechanism of ammonium inhibition. Results presented here show that inhibition of methane consumption by non-ammonium salts can be explained in part by ion-exchange reactions: cations desorb ammonium, with the level of desorption varying as a function of both the cation and anion added; differential desorption results in differen

Abstract:

The irrigated soils in dry and semi-arid areas suffer from the problem of salt accumulation because of not using sufficient leaching water to remove the salts added with the irrigation water. Soil salinity contributes to a decrease in the growth and productivity of plants grown in those conditions, as well as affecting the physical, chemical and hydraulic properties of the soil. The reclamation process is a radical solution to the problem of salinization, and one of the most important basic ingredients for the success of the process of reclamation of saline soils is to determine the optimal am

The solonetz soil cover 21.7 % of Novosibirsk Region, or 3 686.2 thousand hectares. In the Barabinsk lowland and northern Kulunda, solonetz soil is seen as agricultural land, as it doesn’t make solid massifs, but occur as small spots among zonal soils (black soils, meadow-black soils and black earth-meadow soils). Regardless the vast area, solonetz soils fulfil 20 - 25 % only of the needs of the livestock industry, which is caused by low productivity in the natural state (1.0 - 3.0 c/ha of dry matter in the steppe and 3.0 - 5.0 c/ha in the forest steppe).

Abstract:

Selected farmlands in southern Baja California, Mexico, were surveyed to determine the levels and the causes of salinization/sodication in irrigated agricultural soil. The salt dynamics observed in profiles differed from farm to farm. Low EC and high pH levels were observed in the profiles of sandy fields, because the salt composition of these soils can easily change when salts are leached by irrigation water that contains carbonates of sodium. On the other hand, high levels of salinity and sodicity were observed in the soils of clayey fields. Soil salinization/sodication is complexly interrel

The search for life on Mars is predicated on the idea that Earth and Mars life (if present) should be both carbon- and water-based with similar forms of evolution. However, the astrobiology community can currently only investigate plausible Martian microbial ecosystems by using Terran life-forms as proxies. In order to examine how life might persist on Mars, we used a hypopiezotolerant bacterium (def., able to grow at 7–10 hPa)—Serratia liquefaciens—in growth assays with four Mars analog soils conducted under a subset of simulated Martian conditions including 7 hPa, 0 °C, and a CO2-enriched an

Abstract:

The results of this study indicate the importance of groundwater flow and water table depth on the genesis, characteristics and distribution of soils within a hummocky morainal landscape. Non-saline and non-carbonated soils in upland depressions can be attributed to "depression-focused" recharge by snowmelt and snowmelt runoff in the spring, as evidenced by deep sola and/or eluvial horizons. Non-saline and carbonated soils on lower slopes adjacent to depressions are associated with local discharge and/or lateral flow from the adjacent groundwater mounds under the depressions in spring, as well

Abstract:

Sodic soils are widespread in Australia reflecting the predominance of sodium chloride in groundwaters and soil solutions. Sodic soils are subject to severe structural degradation and restrict plant performance through poor soil-water and soil-air relations. Sodicity is shown to be a latent problem in saline-sodic soils where deleterious effects are evident only after leaching profiles free of salts. A classification of sodic soils based on sodium adsorption ratio, pH and electrolyte conductivity is outlined. Current understanding of the processes and the component mechanisms of sodic soil beh

Abstract:

ABSTRACT Atmospheric methane consumption by Maine forest soils was inhibited by additions of environmentally relevant levels of aluminum. Aluminum chloride was more inhibitory than nitrate or sulfate salts, but its effect was comparable to that of a chelated form of aluminum. Inhibition could be explained in part by the lower soil pH values which resulted from aluminum addition. However, significantly greater inhibition by aluminum than by mineral acids at equivalent soil pH values indicated that inhibition also resulted from direct effects of aluminum per se. The extent of inhibition by exoge

Areas of sorted step patterned ground from Nuntherungie and Gap Hills Landsystems were selected and the soil properties compared.

Despite occurring within different Landsystems, the suite of soil chemical properties (EC, soluble cations, and pH) between the bare and vegetated area within the patterned ground were statistically the same in most cases.

Salt accumulation in soils poses severe challenges for crop production in arid and semi-arid regions. Scarcity of rainfall and a high evaporation rate in these regions are considered major reasons for salt accumulation. It drastically reduces the leaching of excessive salts below the root zone of crops. The toxic effects of salts on plants can be greatly reduced with the use of biological and inorganic amendments.
