棕漠土（brown--desert soil）也称棕色荒漠土，是暖温带漠境条件下发育的地带性土壤类型。土壤的形成过程完全受漠境水热条件所左右，碳酸钙、石膏与易溶盐的聚积作用普遍。地表通常为成片的黑色砾幂，全部表面由砾石或碎石组成。削面分化比较明显，腐殖含量极低，多小于0.3%，呈碱性反应，土壤代换量很小。在我国主要分布在甘肃河西走廊西部、新疆东部和塔里木盆地等。
SOC含量相对更低的灰棕漠土比风沙土退耕后土壤C、N的增加更为明显。
Typic Calciorthids with lower SOC concentration had relatively lower C sequestration rate but more significant effects of C and N sequestration compared with Typic Torripsamments.
黄土是在相对冷干气候条件下发育的成熟的灰黄色古土壤，不同地区黄土所属土壤类型主要为灰钙土、栗钙土、棕钙土、棕漠土和黑垆土。
But compared with reddish paleosols, it was formed in dry and cold conditions, so, loess even could serve as an indicator of dry and cold climate.
