High settling velocities and regular flooding, as present in the foreland, cause high inputs of mineral sediments and carbonate, moderate sulfur dynamics and thus the development of calcareous soils.
Exogenous u1 inputs include eolian and slopewash inputs (sedimentations) of mineral and organic materials, mass wasting accumulations and the like.
The studied cultural layer of Grub-Kranawetberg shows evidence of 1) substantial anthropogenic input of organic and mineral material, 2) bioturbation by a diverse soil fauna including mollusks and earthworms, 3) translocation of carbonates, indicating soil-forming processes, 4) trampling and 5) a preserved, though bioturbated, occupation surface without signs of erosion or redeposition.
Based on the model of climate controlling fluvial cycles in the Beijing Plain, we suggest that the higher inputs of magnetic minerals, as a result of increasing precipitation, resulted in higher values of k and SIRM in the interglacial periods and that decreasing precipitation in the glacial periods reduced the inputs of magnetic minerals, resulting in lower values of k and SIRM.
In contrast, the lowest lake [P] and [DP] (median 50 and 11 μg L−1, respectively) occurred on the coarse-textured landform, reflecting greater inputs of deep mineral-groundwater with low [P] from quartz-rich substrates.
Conventional agriculture largely depends on the input of phosphorus fertilizer; the output of mineral phosphorus is expected to reach a peak around 2030, and then to take a downward turn (Cordell et al. 2009).
Input of tephra with easily weatherable minerals may account for metastable mineral formation.
In this regard, we hypothesize that the main input of heavy metal contamination include mineral feed ingredients which, in turn, are included in compound feed to meet animals' nutritional requirements.
Under a warming climate scenario, an increase in the thickness of the thawing depth will intensify the input of inorganic components from deep mineral horizons and possibly underground waters thus producing the enrichment of large lakes in Fe-rich colloids and particles.
Thus, we would not expect CO2 efflux from the mineral soil to be affected by our treatments until decomposition processes were sufficiently advanced to affect the input of carbon and nutrients to the mineral soil.
These models need the input of characteristic breakage parameters for the mineral of interest and these are often determined in a small size laboratory ball mill and scaled up by the program to the conditions of a full-scale ball mill.
