Earthworms are known to be important regulators of soil structure and soil organic matter (SOM) dynamics, however, quantifying their influence on carbon (C) and nitrogen (N) stabilization in agroecosystems remains a pertinent task. We manipulated population densities of the earthworm Aporrectodea rosea in three maize-tomato cropping systems [conventional (i.e., mineral fertilizer), organic (i.e...

Researchers seek to identify dry lake bed deposits on Mars, if present. The Global Surveyor TES and Mars Odyssey THEMIS are primary tools in this search. However, there are no published thermal infrared spectrometer (hyperspectral) airborne studies of a dry lake bed. Here we present the first such study and the impacts on TES/THEMIS interpretations. This research addresses a looming gap in the ...

The coastal area of the Ma river delta is formed by interaction continental and marine processes, between neo-tectonic activities exogenous natural factors human during Late Holocene. Using remote sensing geoscience research methods (granulometry, paleontology, geochemistry, clay mineralogy) geomorphological studies (geneses, morphology, dynamics) combined with field survey, this area, except d...

This study is based on the Shihmen Reservoir silt, where the largest quantity of silt is deposited and is located right next to the National Taiwan University of Art, and with combinations of other simple components, like various kinds of clay, plant ashes or other raw materials, to produce quality glazes that can perform artistic charm and give great additional values. The development of the n...

Determination and recognition of relative distribution of chemical forms of each element and their relationship with physical, chemical and soil clay minerals can help researchers to manage soil fertility better. This research attempted to recognize chemical fractions of zinc (Zn) and copper (Cu) in some surface and subsurface soil samples of Kohgiluyeh and Boyer-Ahmad province and their relati...
