Of the natural processes that concentrate dispersed environmental contaminants, landscape fire stands out as having potential to rapidly concentrate contaminants and accelerate their redistribution. This study used rainfall simulation methods to quantify changes in concentration of a widely dispersed environmental contaminant (global fallout 137Cs) in soils and surface water runoff following a ...

Dieback of native Eucalyptus largiflorens forests is an increasing problem on the floodplains of the lower River Murray, southern Australia. Salinisation of floodplain soils, as a result of the changed hydrological management of the River Murray, appears to be a primary cause of the dieback. Regulation of the River Murray has reduced the frequency of large flood events by a factor of approximat...

This article reviews peer-reviewed publications and book chapters on the history, epidemiology, genetics, ecology, pathogenesis, pathology and management of podoconiosis (endemic non-filarial elephantiasis). Podoconiosis is a non-infectious geochemical elephantiasis caused by exposure of bare feet to irritant alkalic clay soils. It is found in at least 10 countries in tropical Africa, Central A...

d-coder is a fertilizer with a new slow-release mechanism consisting of an organo-mineral matrix that releases the nutrients only in the presence of growing plants. pot and field experiments were carried out to study the release pattern of n from d-coder. the experiments included grown and bare soil plots. the fertilizer treatments were d-coder, ammonium nitrate (anpreplant), and the control. a...

growth and productivity of plants are mainly affected by various environmentalfactors in different ecosystems and natural habitat in the world. this research aims to studythe existing relationships between the phytosociology characteristics of thymuskotschyanus and environmental factors in order to find the most important factorsgoverning development of the species in middle taleghan rangelands...

Accurate approaches to aboveground biomass (AGB) estimation are required support appraisal of the effectiveness land use measures, which seek protect grazing-adapted grasslands atop Qinghai-Tibet Plateau (QTP). This methodological study assesses one commonly used visible band vegetation index, Red Green Blue Vegetation Index (RGBVI), obtained from unmanned aerial vehicle (UAV), in estimating AG...

Ecological restoration of mine tailings have impact on soil physiochemical properties and microbial communities. The surface soil has been a primary concern in the past decades, however it remains poorly understood about the adaptive response of microbial communities along the profile during ecological restoration of the tailings. In this study, microbial communities along a 60-cm profile were ...

introduction: soil has an important role in nutrient cycle and an important function in storage, refinement, and movement of nutrients for the living and non-living parts. soil pollution of heavy metals and elements is one of the common pollution impacts of human activities, especially industry. realization of distribution pattern of these elements and their anthropogenic sources is a major par...
