日本理化研究所环境资源研究中心菊地淳领导的国际研究小组开发出“利用半碳化生物质改良土壤综合评价法”,可通过综合分析土壤的物理、化学和生物学特征对土壤进行改良。土壤由大小不一的沙石、经微生物分解后残留的腐殖质以及由雨水、河川等带入的矿物质等多种物质组成。这些物质交织形成团粒结构,使土壤保持适度水分,并通过空气通道向植物和土壤生物提供氧气。

As we walk along a forest path, the soil beneath our feet seems like a uniform substance. However, it is an intricate network of soil particles, pores, minerals, soil microbes, and more. It is awash i...

在全球范围内,土壤保持着地球的一小部分水分。然而这些水分在水、碳和能量的循环过程中依然是一个至关重要的方面:它决定了一个地区对于干旱及洪涝的敏感程度,决定了植物能否很好地生长并吸收大气中的碳,同时还决定了地球的升温与冷却——这是暴风的一个关键驱动因素。然而在大多数情况下,土壤水分的监测一直依赖于稀疏设置在地面上的探测器。美国剑桥市麻省理工学院(MIT)水文学家Dara Entekhabi表示:“在...
