Development and stabilisation of soil structure via interactions between organic matter, arbuscular mycorrhizal fungi and plant roots

摘要: A clearer understanding of the mechanisms that underpin the development and stabilisation of soil structure would enable a more predictable restoration of degraded soil. A hierarchical model of soil aggregation (HM) is posited that predicts soils to be self-organising systems, mediated via interactions and feedbacks between their mineral constituents, organic matter and biotic activity, which serve to create and stabilise soil structure. To determine the contribution of these latter constituents, combinations of organic matter (compost), living …
