Temporal variations of runoff and sediment in different soil clay contents using simulated conditions
clay erosion plot rainfall simulator
2015/3/9
Soil clay content (SCC) plays an essential role in the processes of infiltration, seal and crust formation, runoff, and soil erosion. The role played by SCC in water erosion has received much attentio...
The effect of the soil compaction on the contents of alfalfa root reserve nutrients in relation to the stand density and the amount of root biomass
alfalfa soil density root reserve nutriet
2015/1/30
The reserve root nutrients influence the overwintering, regrowth, yield, and persistence of alfalfa plants. The total amount of the root reserves is considered more important than their concentration....
Contents of Potentially Risk Elements in Natural and Reclaimed Soils of the Sokolov Region
soil reclamation potentially risk elements principal component analysis
2015/1/28
Anthropogenic soils are formed by human activities. The contents of potentially risk elements are one of the most important criteria of the exploitability of such soils for the agricultural production...
