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 ...

Ecological Solutions and Evidence, Volume 6, Issue 3, July–September 2025.Urban agriculture is in an intermediate state between traditional urban green spaces and conventional rural farms in terms of environmental impacts, so that its contribution to urban sustainability requires complementarity with other green spaces. Abstract As cities expand, they encroach on agricultural land, impacting food production and natural ...

Shuitu Baochi Xuebao, 2018 为了研究不同坡向土地利用类型对土壤性质的影响，以渭北旱塬区5种土地利用类型（不同坡向）为研究对象，系统分析该区不同坡向土地利用类型剖面土壤物理、化学和生物性质的差异。结果表明：（1）除土壤pH和土壤颗粒组成外，5种土地利用类型土壤含水量、总孔隙度、有机质、全氮、微生物量碳和氮含量总体随土层加深呈下降趋势，土壤容重则相反。（2）0-30 cm土层，阳坡农用地土壤含水量、黏粒含量和pH最高，粉粒和全氮含量最低；人工草地砂粒和全氮含量最高，黏粒含量最低；人工林地土壤总孔隙度、土壤有机质、微生物量碳和氮含量最高，
