Analysis of samples of the 0 to 10-cm soil depth collected at 65 locations under six vegetation communities snowed that prairie and cedar-hardwood communities occurred on calcareous (range, pH 6.97.9) soils with low silt concentrations (20-54%), and that pine and oak communities occurred on acid (pH 4.36.3) soils with high silt (54-80%); this represented a distinction between communities on soi...

The last decade has seen a growing and renewed interest regarding anthropogenic soils which owe their dominant characteristics to past land management practices. These soils, besides being of particular pedological interest, are also of high archaeological significance given the high density of sites which frequently occurs on them. According to the World Reference Base for Soil Resources, anth...

Concentrations of copper (Cu), lead (Pb), chromium (Cr), mercury (Hg), and arsenic (As) were measured in arid agricultural and irrigated agricultural soils collected in Daba Village, Shajiawuan Village, Gangou Village and Sifangwu Village, located in central Gansu Province, China. Concentrations except Hg and Pb were lower than the background values in grey calcareous soil in the selected arid ...

The event of partly grain-free ear is a crucial problem which can result in severe reductions in corn yield. In a two year field investigation, during 2003-2004, an experiment was conducted to determine the effect of  boron (B) and zinc (Zn) application on yield and yield components of corn (Zea mays L.) plants grown in a B and Zn-deficient calcareous soil (fine, carbonatic, thermic, Typic Hapl...
