Burning the forest just once can leave behind enough black carbon to keep the soil fertile for thousands of years.
森林仅仅燃烧一次就能留下足够的黑碳，来保持数千年土壤肥沃。
Atmospheric Marine aerosol was derived from seawater gaseous substance soil dust ash fly from burning coal ash fly from burning fuel and industrial waste at dalian sea area.
结果表明，大连海域大气气溶胶物质主要来自海水、气态物、土壤尘、煤烟尘、燃油灰和工业废料。
The ground was super heated, burning a policeman's leg when he went to investigate, and the soil so soft there it swallowed up sheep.
地面变得超级热，当一个警察去调查的时候，烧伤了他的腿；那儿泥土很松软，把绵羊也吞没了。
Land use change is still a major source of carbon dynamics emission due to burning and cultivation, which caused to decline soil organic carbon contents in soils and degrade soil quality.
因烧垦而引起的土地利用变化仍然是碳素释放的主要来源，从而导致了土壤有机碳含量下降和土壤质量退化。
Tundra burning may also release more organic carbon, a greenhouse gas currently stored in the soil, into the atmosphere.
苔原燃烧也可能释放出更多的有机的碳，二氧化碳目前储存在土壤中，这样将会到大气层中。
The results show that the great differences between the soil fertility of control burning and that of non-burning are resulted by the different ground clearances.
结果表明：采伐迹地的不同清理方式导致了林地肥力的较大差异。
Fire can also reduce the content of organic matter (SOM) in the surface layer, and it's most obvious in the O and A soil layers at the same year after burning.
