A pot experiment was conducted to study interactive effects of arbuscular mycorrhizae (AMs) and maize (Zea mays L.) straws on wheat (Triticum aestivum L.) growth and organic carbon (C) storage in a st...
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...
