Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Transition metal‐based amorphous/crystalline (a/c) heterostructured catalysts have garnered significant attention due to their exceptional activity, stability, and cost‐effectiveness. However, the precise synergistic regulation of interfacial composition and phase states remains challenging.

Functional Ecology, Volume 39, Issue 10, Page 2889-2904, October 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract In the Southwest Australian Biodiversity Hotspot, the greatest plant species diversity tends to occur on the most phosphorus (P)‐impoverished soils. Many plant species in this P‐impoverished environment release root carboxylates that mobilise soil P which is a more ...

Plant nutrient‐acquisition strategies contribute to species replacement during primary succession
Journal of Ecology, Volume 113, Issue 4, Page 988-1003, April 2025.Pioneer species Hippophae acquires phosphorus and nitrogen mainly by ‘mining’ and N2‐fixing strategies and thus dominates in the beginning of primary succession. As soil nutrient availability increases with the mobilization of apatite‐P and input of N‐rich plant residues, Hippophae' strategies become less efficient than Populus's scavenging strategies.

Functional Ecology, Volume 39, Issue 2, Page 621-634, February 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Tropical forests are generally characterized by high species diversity and low soil phosphorus (P) availability. Although tropical plants have evolved adaptations to low soil P availability, we know relatively little about the strategies of different groups of species ...

Shuitu Baochi Xuebao, 2003 通过温室盆栽和大田试验研究旱作水稻在施用中量磷肥条件下,土壤水分对红壤中几种磷的含量和动态的影响。研究表明:土壤水分水平和采样时间对红壤全磷、有效磷、有机磷和不同形态的无机磷含量都有极显著的影响,且相互间的交互作用明显。栽种水稻后总体来说,土壤全磷、有机磷和O-P含量均有一定的提高,有效磷和Al-P、Fe-P、Ca-P含量则下降;土壤中不同形态无机磷含量为O-P>Fe-P>Al-P>Ca-P;大田和盆栽实验相比,在4种形态的无机磷、全磷和有机磷的排列顺序、演变趋势等方面基本一致,但有效磷则出现相反的结果,

Shuitu Baochi Xuebao, 2005 由于长期种植蔬菜，石灰性菜园土壤中的磷素在剖面中发生了分异，直接影响到其它营养元素的吸收和蔬菜的产量及品质。通过对不同植菜年限石灰性菜园土壤剖面磷素形态分级及其变异规律的研究，探讨了全磷、有效磷和无机磷不同形态的变异特征以及其磷素形态分布与其它土壤性质的关系。研究结果表明，石灰性菜园土壤耕层全磷、有效磷、无机磷与有机磷均比粮田富集强烈，有效磷源的无机磷形态含量与植菜年限呈明显的正相关，各形态无机磷含量的垂直分布与粮田存在显著关系，Ca2-P、Ca8-P、Fe-P含量为表层强烈富集，向下骤减的垂直分布特征。

Shuitu Baochi Xuebao, 2007 对棕壤26年长期定位试验的无机磷分级表明:长期施入有机肥或化学磷肥,除了Ca10-P含量在耕层减少外,其它各形态无机磷含量都有所增加;仅施N肥或不施肥,Al-P,Fe-P,O-P,Ca10-P含量均减少,Fe-P,Al-P,Cas-P,Ca2-P占无机磷总量的比例增加,而O-P,Ca10-P则下降了.各形态无机磷的剖面分布相似,均为先下降而后略微上升.相关分析和逐步回归分析表明,Ca2-P,Ca8-P,Al-P,Fe-P,O-P与速效磷之间达到1%的极显著水平,Ca10-P与速效磷之间达到5%的显著水平.

Shuitu Baochi Xuebao, 2008 采用室内模拟土柱淋洗方法研究了无机复合肥、有机复合肥、猪粪堆肥和花生麸4种肥料单施和两两混施条件下氮磷在赤红壤中的淋失特征。结果表明,各处理总氮淋失率在43.2%～74.8%之间,总磷淋失率在0.01%～0.08%之间,赤红壤中肥料氮淋失严重,肥料磷淋失有限。肥料单施处理的无机氮淋失量和有机氮基本相近,肥料混施处理的无机氮淋失量远高于有机氮;各施肥处理磷的淋失均以颗粒磷为主。肥料混施显著增加铵态氮和无机氮淋失,减少有机氮和总氮淋失。猪粪与复合肥混施减少颗粒磷和总磷淋失 ...

Shuitu Baochi Xuebao, 2016 以济宁地区引黄充填复垦、引湖充填复垦和预复垦3种复垦方式样地土壤为研究对象，通过分层采样和室内分析，研究不同复垦方式下土壤无机磷（Ca2-P、Ca8-P、Al-P、Fe-P、O-P、Ca10-P）的空间分布情况，并找出影响复垦土壤速效磷偏低的原因。结果表明：（1）3种复垦方式下的复垦土壤全磷含量在0.42～0.77 g/kg之间，土壤速效磷含量在0.65～5.22 mg/kg之间，复垦土壤全磷含量丰富而速效磷偏低；（2）复垦土壤各无机磷形态以难被植物利用的Ca10-P和O-P含量最高 ...
