Globally increasing atmospheric nitrogen (N) deposition has altered soil phosphorus (P) transformations and availability, and thereby influenced structure and function of terrestrial ecosystems. Edaphic characteristics and chemical form of deposited N could be important factors determining impacts of N deposition on soil P transformations, yet the underlying mechanisms remain largely unknown. Objectives of this study were to examine how mineral-N and amino N differently affect P fractions, and identify key soil properties determining N addition impacts on soil P transformations. Considering that amino N is an important component of deposited N and forest soils vary greatly in different regions, the results of present study can guide the management of forests across different soils under ongoing N deposition scenarios. We conducted a 60-day laboratory experiment to investigate the effects of N addition (NH4NO3 and glycine) on soil P fractions and related biochemical properties in four representative forest soils (brown, yellow brown, aeolian sandy, and red soils) in China. Glycine and NH4NO3 were separately added at three rates (5, 10 and 20 g N m–2 yr–1). Firstly, the percent changes in organic P fractions with N addition were significantly greater than changes in inorganic P fractions across all soils. Secondly, the percent changes in P fractions with glycine and NH4NO3 additions were significantly correlated across all soils and treatments. However, glycine addition had significantly greater impacts on organic P fractions than NH4NO3 addition in the aeolian sandy and red soils with low organic carbon content. Thirdly, P fractions responded differently to N addition among the four soils. N-induced changes in microbial biomass and phosphatase activities, pH, exchangeable Ca2+ and Mg2+ contributed differently to the changes in P fractions with N addition in the four soils. The different responses of P fractions to N addition in the four soils were mainly generated by the differences in extent of microbial N limitation, acid buffering capacity, and cation exchange capacity among the soils. The different impacts of mineral and amino N on soil P fractions can be ascribed to their divergent effects on soil pH, microbial biomass and activities.
全球范围内不断增加的大气氮（N）沉积改变了土壤磷（P）的转化和供应，从而影响了陆地生态系统的结构和功能。土壤特性和沉积氮的化学形态可能是决定氮沉积对土壤磷转化影响的重要因素，但其潜在机制在很大程度上仍然未知。本研究的目的是考察矿物氮和氨基氮如何对磷组分产生不同影响，并确定决定氮添加对土壤磷转化影响的关键土壤特性。考虑到氨基氮是沉积氮的重要组成部分，而不同地区的森林土壤差异很大，本研究的结果可指导在持续氮沉积情况下不同土壤的森林管理。我们进行了一项为期 60 天的实验室实验，研究了氮添加（NH4NO3 和甘氨酸）对中国四种代表性森林土壤（棕壤、黄棕壤、风化沙土和红壤）中土壤磷组分及相关生化特性的影响。甘氨酸和 NH4NO3 的添加量分别为 5、10 和 20 g N m-2 yr-1。首先，在所有土壤中，添加氮后有机磷组分变化的百分比明显大于无机磷组分的变化。其次，在所有土壤和处理中，添加甘氨酸和 NH4NO3 时 P 分量变化的百分比明显相关。然而，在有机碳含量较低的风化沙土和红壤中，添加甘氨酸对有机磷组分的影响明显大于添加 NH4NO3。第三，四种土壤中的磷组分对氮添加的反应不同。氮引起的微生物生物量和磷酸酶活性、pH 值、可交换 Ca2+ 和 Mg2+ 的变化对四种土壤中添加氮后 P 组分的变化有不同的影响。四种土壤中 P 部分对氮添加的不同反应主要是由于微生物对氮的限制程度、酸缓冲能力和阳离子交换能力的不同造成的。矿物氮和氨基氮对土壤中磷组分的不同影响可归因于它们对土壤 pH 值、微生物生物量和活性的不同影响。
