土壤是有“生命”的,1克含腐植酸的土壤富有3.7亿微生命。2015年6月13日,联合国新修订的《世界土壤宪章》开宗明义,土壤为地球生命之本。2015年12月12日,联合国《巴黎气候大会》倡议4‰土壤碳封存,是土壤维碳顾命的关键。2016年5月31日,国务院发布《土壤污染防治行动计划》,维护土壤健康成为焦点。纵观土壤生态系统,唯有“土壤肥力—腐植酸(有机质)—微生物”三者最具互动力。在土壤中,腐植酸及其他有机物给微生物提供碳源、氮源并伴其终身;微生物通过不断分解
Soil is “life”, 1 gram of humic acid-rich soil rich in 370 million micro-life. On June 13, 2015, the UN’s newly revised “World Soil Charter” was made clear that the soil is the essence of life on earth. December 12, 2015, the United Nations “Paris Climate Conference” initiative 4 ‰ soil carbon sequestration is the key to the soil carbon footprint. On May 31, 2016, the State Council released the “Soil Pollution Prevention and Control Action Plan” to focus on soil health. Throughout the soil ecosystem, only “soil fertility - humic acid (organic matter) - micro-organisms” the three most interactive. In the soil, humic acid and other organic substances provide carbon sources, nitrogen sources and their lifetime to microorganisms; microorganisms are constantly decomposed
