Mycorrhizas and soil structure.
In addition to their well-recognized roles in plant nutrition and communities, mycorrhizas can influence the key ecosystem process of soil aggregation. Here we review the contribution of mycorrhizas, mostly focused on arbuscular mycorrhizal fungi (AMF), to soil structure at various hierarchical levels: plant community; individual root; and the soil mycelium. There are a suite of mechanisms by w...
متن کاملMycorrhizas for Forestry and Agriculture
This chapter provides an introduction to the concepts and procedures that would be required to plan. initiate. monitor and analyse experiments involving mycorrhizal inoculation or fertilizer application treatments. The following discussion is concerned primarily with larger field trials required in plantation forestry. but most principles apply equally to smaller experiments conducted in the gl...
متن کاملRevegetation Priorities
Revegetation is a needed means of mitigating man-made and natural disturbance. Our current ability to address environmental insults contrasts sharply with that existing when John Muir fi rst sowed the roots of environmental awareness or Aldo Leopold and Hugh H. Bennett inspired a land ethic and a sense of stewardship. We now have considerable revegetation science and experience and—equally impo...
متن کاملPodocarp Roots, Mycorrhizas, and Nodules
Podocarps are often found on lownutrient soils and further exacerbate nutrient limitation through the production of recalcitrant litter. Understanding podocarp ecology therefore depends on understanding the root adaptations of podocarps to obtain nutrients. The roots of podocarps are heterorhizic (having two root forms) with abundant spherical determinate short roots, a unique form of largely u...
متن کاملInoculated Legumes and Revegetation/roadside Plantings
In response to the vast loss of prairie area in western and southern Minnesota and the concern over plant genetic loss and soil erosion that resulted, this study set to determine the success of prairie reconstruction along Minnesota roadways. Areas around rest stops on major highways were seeded with prairie plants. As nitrogen is commonly limited in natural environments, legumes-known for thei...
