Description:
Despite the importance of phosphorus (P) as a macronutrient, the factors controlling storage of organic phosphorus (OP) in soils are not yet well understood. The objective of this meta-analysis was therefore to investigate the distribution of OP, organic carbon (OC), and inorganic P (IP) in particle size fractions depending on climate, latitude and land use, based on data from published studies. The clay size fraction contained on average 8.8 times more OP than the sand size fraction and 3.9 and 3.2 times more IP and OC, respectively. The OP concentrations of the silt size and clay size fractions were both most strongly correlated with mean annual temperature (MAT) (R2=0.30 and 0.31, respectively, p
