Introduction Although soil clearly is a dependent variable of four state factors (climate, parent material, topography, and time), the...
One of the approaches to utilize various wastes in large quantities is to produce aggregates artificially by pelletization (also known as agglomeration). These find their practical application in producing lightweight concrete. Artificial aggregates are produced by allowing powder materials to agglomerate ...
Data were gathered at three microsites at each burrow: (1) at the burrow entrance, (2) at the impacted area around the burrow (i.e. disturbed by the deposition of excavated soil), and (3) at a control site close to the burrow. In the mesic grassland and the semi-arid savannah, th...
but factors such as precipitation and soil moisture are potentially more limiting and more important in determining distribution patterns (Dobrowski et al.2013). Aitken et al. (2008) found that the degree to which variation in precipitation explains phenotypic variation among populations is greater in...
The site has a dark chestnut soil (Calcic Chernozem according to ISSS Working Group RB, 1998), with a loamy-sand texture (Bai et al. 2010). Long-Term Nitrogen Enrichment Experiment The establishment of the N enrichment experiment was described by Bai et al. (2010) and is briefly ...
It is possible to classify the materials from the magnetic point of view as a function of the number of Bohr magnetons, whose parameter can be calculated from the Langevin function, first derived for the noninteracting paramagnetic spins and to the noninteracting: σ ⁄σs...
The Gangdese arc is located in the southern part of the Lhasa terrane in southern Tibet (Fig. 2G–H) and was formed by the Cenozoic collision between the Indian and Asian continents. Hafnium isotope mapping of the Lhasa terrane revealed that the northern and southern subterranes were accreted ...
Highly significant correlations were obtained between the annual irrigation requirement on the one hand and soil texture and net evapotranspiration on the other hand. By multiple regression it was found that these two factors, together with number of days of irrigating, accounted for 91 to 94% ...

by polyvinyl alcohol, which are completely resistant to water. The suspension of polyvinyl alcohol prepared according to the invention may also be used as erosion protection for surface soil, especially when calcium phosphate, which acts as a finely divided artificial fertilizer is contained therein ...
