ABSTRACT The dynamics of soil organic carbon (SOC) turnover are significantly modulated by the supply of essential nutrients, with particular emphasis on nitrogen (N) and phosphorus (P). For the typical desert steppe, the responses of soil carbon (C) turnover to the addition of N and P and the under...
