Cellulose, hemicellulose, lignin contents, C:N and lignin:N ratios were significantly greater (LSD, <em>P</em> &lt; 0.05) in soils with the E⁺ residues than in those with E⁻ residues. Additionally, the E+ plant residues consistently contained significantly less N (LSD, <em>P</em> &lt; 0.05).

We conducted a 4-year N addition experiment to investigate the response of both plant and arbuscular mycorrhizal (AM) fungal richness to the combined addition of ammonium (Am) and nitrate (Ni) in a revegetated grassland rehabilitated (with a focus on restoration) on the Qinghai–Tibet Plateau.

However, when Ni and Am were combined, only Ni20 plus Am20 among all combinations reduced both plant and AM fungal richness. Both soil nitrate-N and plant species richness jointly drove changes in AM fungal richness, but plant species richness was the main factor affecting AM fungal richness under N addition.
