对不同土地管理措施下独联体乌拉尔地区的重壤质草皮灰化土壤中的腐植酸的元素组成和结构进行研究。腐植酸的组成和性能在长期清洁休耕地,杂草丛生休耕地(荒废的土地)和轮作休耕地是不同的。定期使用肥料的轮作地和杂草丛生休耕地的土壤中的腐植酸,富含主要的(核心的)和次要的部分。这样的结构确保了腐植酸积极参与碳循环且同时保存了土壤的肥力。
The elemental composition and structure of humic acid in the ashes of the heavy loam turf in the Ural region of the Commonwealth of Independent States under different land management practices were studied. Humic Acid Composition and Performance In long-term clean fallows, weeds are fallow (abandoned land) and fallow fields are different. Humic acid in soil from fallow fields and overgrown fallow fields that regularly use fertilizers is rich in major (core) and minor fractions. This structure ensures that humic acid actively participates in the carbon cycle while preserving soil fertility.
