A dataset of soil phosphorus fractions and physicochemical properties under 13-year nitrogen addition in biological soil crusts of the Gurbantunggut Desert (2023)
Listed in ScienceDB
This dataset is based on a 13-year (2010–2023) N addition gradient experiment at the southern Gurbantunggut Desert, comprising 240 samples of lichen- and moss-dominated biological soil crusts and underlying 0–5 cm soils.
Description
Six N levels (0–12 g N/m²/yr) were applied twice yearly. Samples were collected in April and July 2023.
The dataset includes 26 variables: nine modified Hedley P fractions, available P, total P, soil moisture, pH, EC, total N, nitrate, ammonium, organic C, Fe, Al, Ca, and alkaline phosphatase activity. It supports research on dryland P cycling under N deposition and biological soil crust microbial ecology.
