Soil microorganisms can do both, mineralize and synthesize organic and condensed phosphate (P) species. Whereas P mineralization has been extensively studied, few studies have assessed the biological synthesis of organic P species, which can potentially accumulate in soil. The goal of this study was to investigate biotic and abiotic P transformations, particularly the synthesis of organic P species, upon water-soluble P addition in the organic (O) horizons of two beech forest sites with contrasting P availability.

双同位素(33P 和 18O)示踪和溶液 31P NMR 光谱揭示有机土壤层中有机磷的合成



土壤微生物可以同时矿化和合成有机和缩合磷酸盐 (P) 物质。尽管磷矿化已被广泛研究,但很少有研究评估可能在土壤中积累的有机磷的生物合成。本研究的目的是研究生物和非生物磷的转化,特别是有机磷形态的合成,在两个山毛榉林地的有机(O)层中添加水溶性磷后,并对比磷的利用率。
