Many alluvial soils along navigable waterways are affected by disposal of dredged sediments or overbank sedimentation and contain metal concentrations that are elevated compared to baseline levels. Uptake patterns for metals and other elements by several volunteer Salix species growing on these sites were determined during a growing season in field plots and compared with the same species growi...

On fertile alluvial soils on the lakeshore plain of Malawi, maize (Zea mays L.) yields beneath canopies of large F aidherbia albida (syn Acacia albida) trees greatly exceed those found beyond tree canopies, yet there is little difference in soil nutrients or organic matter. To investigate the possibility that soil nutrient dynamics contribute to increased maize yields, this study focused on the...

Because of the high calcium content of its foliage, Cornus florida (flowering dogwood) has been described as a calcium "pump" that draws calcium from deeper mineral soil and enriches surface soil horizons. However, over the last two decades an exotic fungal disease (dogwood anthracnose, Discula destructiva) has decimated populations of this once-common understory species. Its loss, combined wit...

<p>In this research the arsenic contaminations issues are exposed and suitable measures recommended through electrokinetic remediation. The expulsion was assessed using electro kinetic remediation from two different soil tests; alluvial clay red taken Tamilnadu zone. Three distinct cathodic electrolytes—deionized water (DIW), potassium phosphate (KH2PO4), sodium hydroxide—were used to tes...

[1] Several dozen distinct alluvial fans, 10 to 40 km long downslope, have been observed in highlands craters. Within a search region between 0 and 30 S, alluvial fan-containing craters were found only between 18 and 29 S, and they all occur at around ±1 km of the MOLA-defined Martian datum. Within the study area they are not randomly distributed but instead form three distinct clusters. Fans t...

Green manures are widely used in rice production and may influence methane efflux (CH4). Influence of application of Azolla (A. caroliniana Wild.), a widely used biofertilizer for rice (Oryza sativa L.), on CH4 efflux from a flooded alluvial soil planted to rice, and select soil and plant variables were investigated in a field experiment at Cuttack, India. Azolla was either incorporated as gree...

Heavy metals (HM) are among the most hazardous soil pollutants. The intensity of accumulation and distribution HM in soils directly depends on ecological conditions pedogenesis its buffering properties. At same time, a significant as result anthropogenic impacts reduces capacity resistance to pollution. purpose this work was assess pollution Don River delta coast Taganrog Bay Sea Azov undergoin...

The article dwells upon the study of current physico-chemical status alluvial dark-humus soils floodplain hayfields Volga-Akhtuba and Volga delta. Alluvial are formed in special semiaquatic conditions; they result soil-forming processes. Considered to be dynamic both natural anthropogenic conditions. They have subordinate remain barriers accumulators various chemical elements while performing a...
