Adaptations to oligotrophic soils
These soils contain low amount of nutrients. Due to weathering and high rates of leaching, these soils have poor nutrients.
Many plants growing is such nutrient poor soils, possess mycorrhizae, which is an association of roots with fungi. Mycorrhizae help in absorption of nutrients they can be either endo mycorrhizae or ectomycorrhizae. In endo mycorrhizae the fungus lives inside roots. In ectomycorrhizae the fungal hyphase are found outside the root.
