Functional Ecology, Volume 39, Issue 12, Page 3504-3516, December 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Nitrogen (N) deposition strongly affects litter decomposition and nutrient release, thereby reshaping carbon cycling in terrestrial ecosystems. Although most studies have focused on above‐ground litter, the effects of N addition on fine root decomposition and their ...

Review of Policy Research, Volume 42, Issue 6, Page 1496-1508, November 2025.ABSTRACT This study adopts a policy‐centric perspective to explore the complex relationship between sustainable nitrogen management (SNM) and the health risks associated with unsafe drinking water. The critical policy challenge lies in balancing the essential role of nitrogen fertilizers in achieving high agricultural productivity with their ...

Spatial Pattern and Influence Factor Analysis of Soil Organic Matter Based on the GeoDetector Model: Taking Liaoyang—Anshan Area as an Example [PDF]
Spatial pattern of organic matter distribution and its influencing factors in the study area can provide a decision-making basis for territorial spatial planning. The majority of previous studies in this area focused on the soil surface, and most of them

Multiple global change factors alter the scaling of nitrogen to phosphorus in alpine plants
Functional Ecology, Volume 39, Issue 8, Page 2044-2055, August 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometry and allometry of nitrogen (N) and phosphorus (P) reflect nutrient absorption and dynamic allocation by plants, and can be regulated by global change factors (e.g. nitrogen enrichment, climate warming and altered precipitation). Yet, how multiple global

Shuitu Baochi Xuebao, 2005 以黑龙江省海伦黑土地区的农田长期（1985～2003年）定位试验土样为材料，对不同施肥处理土壤有机质含量、土壤全氮进行了系统研究。结果表明，长期无肥处理土壤有机质含量、全氮含量最低；长期施用氮肥、氮磷肥、有机肥处理土壤有机质含量、全氮含量居中；有机肥与化肥配合施用比无肥处理可显著提高有机质水平，增加土壤全氮含量。各处理C／N比值在9．91～13．10之间变动。

Fractal characteristics and related affecting factors of particle size distribution in mangrove soils in Dongzhai Harbor of Hainan [PDF]
, 2008 应用分形理论分析了海南东寨港红树林土壤粒径分布的分形特征及其影响因素,海南东寨港土壤的分形维数为2.302～2.575,分形维数的大小与土壤中的粘粒、盐分、有机质、全氮含量呈显著正相关,外滩红树林土壤的分形维数低于中滩和内滩;随着土壤质地由砂壤土、轻壤土、中壤土、重壤土的变化,分形维数逐渐增大;从陆到海土壤分形维数逐渐减小。群落类型、土壤质地、滩位、含盐量、有机质、全氮含量等是影响海南东寨港红树林土壤分形维数的主要因子。The analysis with fractal theory on the ...

New Phytologist, Volume 247, Issue 3, Page 1117-1128, August 2025.Summary Environmental changes and their effects are among the most pressing topics of today's ecological research. Shrublands, although widespread across the globe, remain understudied in this respect. We conducted a global meta‐analysis of 81 shrubland sites subjected to experimental warming, shifts in precipitation (e.g.

Shuitu Baochi Xuebao, 2017 为探讨水氮调控对设施土壤有机氮组分、全氮和矿质氮的影响，通过膜下滴灌设施番茄田间定位试验，采用灌水下限（W1、W2、W3）和施氮量（N1、N2、N3）的两因素三水平随机区组设计，研究水氮调控对休耕期0—30 cm土层土壤有机氮组分、全氮和矿质氮的影响。结果表明，不同水氮调控下，设施土壤有机氮主要是以酸解态氮为主，总体表现酸解态氮大于非酸解态氮含量。土壤有机氮组分在酸解态氮和非酸解态氮中分配比例差异明显。土壤有机氮各组分含量及占全氮比例的大小顺序为氨基酸氮＞氨态氮＞未知氮＞氨基糖氮。除氨基糖氮 ...
