Cogent Food & AgricultureCurrently, the use of biostimulants is considered an environmentally friendly alternative to synthetic fertilizers. In this work, we investigated the use of a biostimulant obtained from winemaking sludge by enzymatic hydrolysis processes in peat ...

Clay mineralogical database of Canadian soils with a clay mineralogical map of surface soils
, 1993 Soil mineralogical information is of primary importance in the characterization and utilization of soils. Since the first report of clay mineralogical data for Canadian soils in 1937, mineralogical data for approximately 1500 samples from 500 pedons in Canada have been obtained and recorded.

The role of root exudates in changing soil mineralogy and mobilizing trace elements [PDF]
, 2012 Root exudates such as low molecular weight organic acids (e.g. citric acid, malic acid, oxalic acid), phenolic compounds (e.g., flavonoids), and siderophores of microbial or plant origin can alter soil mineralogy in the rhizosphere thereby releasing ...

Archaeometry, EarlyView.Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

Clay-associated organic matter in kaolinitic and smectitic soils [PDF]
, 2002 The primary source of soil organic matter is plant debris of all kinds, such as dead roots, leaves and branches that enter into the soil and are then biologically decomposed at variable rates.

Investigating relationships among strontium, barium, and seasonality in wild baboons
Archaeometry, EarlyView.Abstract Geochemical profiles of Australopithecus africanus and baboon teeth show fluctuating trace elements, possibly reflecting seasonal diets. Here we use laser ablation–inductively coupled plasma–mass spectrometric measurements of calcium‐normalized strontium and barium ratios (Sr/Ca and Ba/Ca) and ion microprobe analyses of oxygen isotopes (δ18O ...

Towards an understanding of thermodynamic and kinetic controls on the formation of clay minerals from volcanic glass under various environmental conditions [PDF]
, 1996 lmogolite is the kinetically and thermodynamically favoured weathering product from rhyolitic volcanic glass in the soil-forming environment. However, on thermodynamic grounds imogolite would also appear to be the favoured alteration product of rhyolitic

Trace Element Patterns in Juvenile Wild Chimpanzee Dentitions
Archaeometry, EarlyView.ABSTRACT Trace elements are used to infer mammalian early‐life diets, environmental toxins, dispersal patterns, stress histories, and weaning ages. Here, we employ laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) to reveal elemental patterns in our closest living relatives, chimpanzees.

Archaeometry, EarlyView.ABSTRACT In 1837, the Tyrolean State Museum Ferdinandeum in Innsbruck, Austria, purchased a Roman bronze statue of a maenad from the 2nd century ce with red garnets as facetted eye inlays found near Brixen, Southern Tyrol. These garnets were investigated using optical microscopy, a portable hand‐held and a stationary micro‐X‐ray fluorescence device, as

Significance of mineralogy in soil mechanics
Geologija, 2002 The research of consistency limits according to Atterberg is of key importance in soil mechanics because it determines, in a simple way, results of interactions between solid and liquid phases in soils, and thus provides possibility to classify them in ...
