Soil Productiveness Indicated by Natural Vegetation

Plutonium and americium behaviour in soil-vegetation cover of natural and semi-natural ecosystems

The results of investigations of transuranic elements { H , , M 0 P u and 2 4 'Am) behaviour in the soil-vegetation cover of natural and semi-natural ecosystems in the regions of Belarus contaminated as a result of Chernobyl acci­ dent have been summarised. The parameters of plutonium and americium vertical migration have been estimated for typical soil varieties; the radionuclides accumulation...

Natural radioactivity in Indian vegetation samples

Background: Vegetation (food stuff) is grown in soil that contains many radioactive elements such as 238U (uranium), 232Th (thorium) and 40K (potassium), which may get deposited either due to radioactive fallout or/and by absorption from the soil and can pose serious health hazards. Materials and Methods: Natural radioactivity, radiological hazards and annual effective dose assessment was carri...

Natural Vegetation Restoration Is More Beneficial to Soil Surface Carbon Sequestration on Loess Plateau

The Loess Plateau of China is a unique geographical unit characterized by extensive loess distribution, serious soil erosion, low vegetation coverage and high soil carbonate content. Since the 1950s, the Chinese government has made great efforts to control soil erosion and restore vegetation, including large-scale tree plantation in the 1970s, integrated soil erosion control in the 1980s and 19...

Soil and vegetation carbon stocks in Brazilian Western Amazonia: relationships and ecological implications for natural landscapes.

The relationships between soils attributes, soil carbon stocks and vegetation carbon stocks are poorly know in Amazonia, even at regional scale. In this paper, we used the large and reliable soil database from Western Amazonia obtained from the RADAMBRASIL project and recent estimates of vegetation biomass to investigate some environmental relationships, quantifying C stocks of intact ecosystem...
