Long-term phosphorus fertilization effects on arbuscular mycorrhizal fungal diversity in Uruguayan grasses

Arbuscular mycorrhizas (AM) are particularly relevant in grasslands due to the high colonization in grasses, main constituent of this ecosystem. Natural grassland (NG) is the dominant ecosystem of Uruguay and it supports one of the main economic activities of the country: livestock. Available phosph...
