There is growing evidence that many nitrogen- and phosphorus-containing organic compounds in soils have on average a higher affinity for adsorption to mineral surfaces than nutrient-free organic compounds. This leads to preferential enrichment of organic nitrogen and phosphorus on mineral surfaces and has important implications for the architecture of organo-mineral associations in soils. Furthermore, the preferential adsorption of organic nitrogen and organic phosphorus compounds likely also influences carbon, nitrogen, and phosphorus cycling in terrestrial ecosystems since sorption of organic compounds to minerals slows down their decomposition. This contribution reviews studies on the sorption of soil organic nitrogen and phosphorus to minerals, guided by the questions; what compounds are soil organic nitrogen and phosphorus composed of and why do these compounds have a comparably high affinity to adsorb to minerals? How do soil properties influence adsorption of organic nitrogen and phosphorus to minerals and why does preferential adsorption of organic nitrogen and phosphorus matter for element cycling? Furthermore, this article identifies hypotheses for future research about the structure of organo-mineral associations, biochemical element cycling, and the role of stoichiometry for soil organic matter dynamics.

土壤中矿物质优先吸附含氮和含磷有机化合物：综述

越来越多的证据表明，土壤中许多含氮和磷的有机化合物平均比无营养的有机化合物对矿物表面的吸附具有更高的亲和力。这导致有机氮和磷在矿物表面优先富集，并对土壤中有机矿物组合的结构具有重要意义。此外，有机氮和有机磷化合物的优先吸附也可能影响陆地生态系统中的碳、氮和磷循环，因为有机化合物对矿物质的吸附减缓了它们的分解。本文回顾了土壤有机氮和磷对矿物质吸附的研究，以以下问题为指导：土壤有机氮和磷由哪些化合物组成？为什么这些化合物对矿物质的吸附力相对较高？土壤性质如何影响有机氮和磷对矿物质的吸附？为什么元素循环优先吸附有机氮和磷物质？此外，本文还提出了有关有机矿物关联结构、生化元素循环以及化学计量对土壤有机质动力学作用的未来研究的假设。
