Tiessen and Moir (Canadian Society of Soil Science 75\u201386, 1993) sequential fractionation method was carried out to determine different forms of soil P and to provide a comprehensive assessment of available P in soils. To explore the relationships between these variables, canonical correlation analyses and Pearson\u2019s correlations were studied.<br \/>\n<strong>Results<\/strong> Significant correlations were found between P fractions and soil properties related to Fe and Al contents, organic matter, and microbial biomass. Besides, significant correlations were found between site index and the studied P fractions except for P extracted with anion exchange membrane (PAEM) and the recalcitrant P fraction.<br \/>\n<strong>Conclusion<\/strong> In the studied soils, P availability is low and the predominant fractions of P are the recalcitrant forms. Aluminum and iron contents in the soils studied play an important role in sorption processes related to the highly and moderately labile P fractions and the organic phosphorus. P availability seems to be regulated by both processes: biochemical mineralization, where phosphatase activity is relevant, and biological mineralization of the soil organic matter. Phosphorus availability affects forest productivity in the Pinus sylvestris plantations studied.<\/p>\n<p><strong>Keywords<\/strong><br \/>\nSite index, Phosphorus fractionation, Sequential extraction, Labile phosphorus, Recalcitrant phosphorus, Microbial biomass<\/p>\n<div class='altmetric-embed' data-badge-type='donut' data-doi='10.1007\/s13595-019-0882-3'  style='float: right; ' ><\/div>\n<p><strong>Publication<\/strong><br \/>\nBueis, T., Bravo, F., Pando, V. et al.
