Roots can increase the channels in the soil
WebThe fungus obtains nutrients, such as sugars, from the plant root. Mycorrhizae also help increase the surface area of the plant root system because hyphae, which are narrow, can spread beyond the nutrient depletion zone. Hyphae can grow into small soil pores that allow access to phosphorus that would otherwise be unavailable to the plant. Web1 Apr 2024 · Root secretions and exfoliations provide nutrition for microorganisms, and root respiration can increase soil temperature and humidity, thereby increasing microorganism viability (Edmondson et al., 2014; Zadeh, 2015). The activities of soil organisms can also loosen the soil and facilitate infiltration (Zadeh, 2015).
