Nitrogen addition boosts alkaline phosphatase-mediated transformation of soil phosphorus under warming in an alpine grassland

A field experiment from 2019 to 2023 to access the influence of N addition, warming and their combination on soil properties, Hedley P fractions, alkaline and acid phosphatase (ALP & ACP) activities, ALP encoding gene (phoD), and root organic acid release in an alpine grassland in the central Qinghai-Tibet Plateau.
