Data from: Fog controls biological cycling of soil phosphorus in the Coastal Cordillera of the Atacama Desert

<p>In this study, we collected topsoil samples (0‒10 cm) from each of 54 subsites, including sites in direct adjacency (&lt; 10 cm) and in 1 m distance to plants, along an aridity gradient across the Coastal Cordillera in the Atacama Desert. The soluble salts anions (NO³^‒, Cl^‒, and SO₄²^‒) and cations (Ca²⁺, Na⁺, Mg²⁺ and K⁺) were tested. And we performed soil sequential P fractionation and the oxygen isotope values of HCl-extractable P_i (δ¹⁸O_HCl-_Pi). </p>
