Role of mycorrhizas in the mineral nutrition of host plants Mycorrhizas are very important in the uptake of nutrients such as P‚ N‚ K‚ Cu‚ Zn and Ca by plants especially in soils low in these nutrients. Since P is the most limiting nutrient in tropical soils‚ mycorrhizas are vital for improving P nutrition particularly for cultivated plants.
