土地退化对生态系统和农业生产率构成重大威胁.
传统的农业实践可能导致严重的土壤退化和减少作物产量.
了解不同农业实践对土壤的影响对于可持续农业至关重要.

研究的目的:

研究传统农业 (CF),有机农业 (OF) 和环保农业 (EFF) 对土壤物理化学特性的影响.
分析土壤微生物群落对这些独特的农业管理实践的反应.
为了澄清耕作方法,土壤健康和微生物组成在斜坡土地果园之间的关系.

主要方法:

三种农业系统的比较:传统 (CF),有机 (OF) 和环保 (EFF) 在斜坡土地上的果园.
分析土壤的物理化学性质,包括碳库存,总,氨-N,pH和可用的.
使用分子技术评估土壤微生物群落结构和丰富度.

主要成果:

有机农业 (OF) 和环保农业 (EFF) 显著增加了土壤碳储量 (3.6至5.1倍) 和总含量.
EFF和OF处理增强了氨-N和微生物生物质碳,同时降低了土壤pH和可用的.
传统农业 (CF) 土壤的和酸盐含量较高,与肥料和除草剂的使用有关,并且有不同的微生物群落 (Gammaproteobacteria, Planctomycetes, Firmicutes, Nitrospirae).

结论:

有机和环保农业实践显然提高了土壤的物理化学特性和碳捕获.
土壤微生物群落的变化与特定的农业实践和土壤营养成分特征密切相关.
环保和有机农业促进有益的土壤微生物种群,与依赖化学投入的传统方法形成鲜明对比.

The Soil Ecosystem

The Soil Ecosystem

Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:

The Roles of Bacteria and Fungi in Plant Nutrition

The Roles of Bacteria and Fungi in Plant Nutrition

Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.
