智能城市应用, 2022 黑土地作为地球上最为珍贵且稀有的土壤资源之一，成为全国重要商品粮生产基地的根本。长期以来，由于存在持续高强度开发利用以及“重用轻养”等问题，导致黑土地面积不断减少，土层不断变薄，地力不断下降，污染不断加重。如果不尽快进行有效的保护，未来黑土地必将会成为制约农业可持续发展甚至威胁全国粮食安全的重要因素。因此，研究如何全面加强黑土地保护，增厚黑土地土层，提升黑土地地力，减轻黑土地污染，构建“管当前更管长远”的长效保护机制，对实现农业可持续发展、保障其粮食安全、维护生态系统平衡等具有重大意义。

Effects of Biochar Application on Nitrogen and Phosphorus Availability in Soils: aReview [PDF]
, 2016 利用生物炭在贫瘠的土壤上培育出肥沃的"黑土"正成为土壤学家研究的热点.氮、磷等大量养分是衡量土壤肥力高低的重要指标,生物炭对其有效性影响表现出极大的复杂性.不同研究得出的结论不尽相同,关键是缺乏对其机制的深入研究.由于氮和磷的不合理利用还可能造成非点源污染而带来环境风险,再加之生物炭施用的不可逆性,必须确保生物炭在任何情况下都不会对土壤和环境带来不利的影响.为此,本文综述了生物炭添加对氮肥和磷肥在土壤-植物系统迁移转化过程中的作用,重点讨论了不同生物炭处理方式对土壤磷素吸附解吸和形态转化的影响 ...
