Defoliation and fertilisation differentially moderate root trait effects on soil abiotic and biotic properties
Journal of Ecology, Volume 111, Issue 12, Page 2733-2749, December 2023., 2023 Our results indicate that defoliation and fertilisation, two common grassland perturbations, have contrasting impacts on root traits of grassland plant species, with direct and indirect short‐term consequences for a wide range of soil abiotic and biotic properties that underpin ecosystem functioning.Yan Liu, Irene Cordero, Richard D.

Methods in Ecology and Evolution, Volume 14, Issue 6, Page 1443-1456, June 2023., 2023 Abstract Successful use of stable isotopes (δ2H and δ18O) in ecohydrological studies relies on the accurate extraction of unfractionated water from different types of soil samples. Cryogenic vacuum distillation (CVD) is a common laboratory‐based technique used for soil water extraction; however, the reliability of this technique in reflecting soil ...Bin Yang, Gbadamassi G. O.

Methods in Ecology and Evolution, Volume 11, Issue 1, Page 22-37, January 2020., 2020 Abstract Climate change is a world‐wide threat to biodiversity and ecosystem structure, functioning and services. To understand the underlying drivers and mechanisms, and to predict the consequences for nature and people, we urgently need better understanding of the direction and magnitude of climate change impacts across the soil–plant–atmosphere ...Aud H.

Shuitu Baochi Xuebao, 2004 通过定位、半定位观测,对贵州喀斯特山区石漠化治理过程中土壤质量特性进行研究,探讨贵州喀斯特山区生态恢复过程中土壤特性以及土壤肥力变化规律。试验结果表明:喀斯特地区石漠化综合治理对土壤物理化学性质的影响较为明显,表现为表层土壤有机质增加,土壤容重降低,孔隙度增加,土壤理化性质改善,保水保肥能力和通道性增加;同时,土壤微生物数量增加,土壤微生物数量增加程度表现为细菌>放线菌>真菌,土壤肥力改善,生产力逐渐提高。罗海波 宋光煜 何腾兵 刘丛强 刘方 刘元生 钱晓刚doaj +2 more sources不同治理措施对退化紫色土土壤生物学活性的影响
Shuitu Baochi Xuebao, 2003 通过对福建省宁化县禾口镇退化紫色土采取3种不同治理措施的土壤理化性质、土壤酶活性和土壤微生物特性的研究,结果表明:治理后土壤有机质、>0.25mm水稳性团聚体含量均有不同程度的提高;治理后土壤细菌、真菌、放线菌数量及微生物总数有明显的增加,土壤水解性酶和氧化还原酶活性得到显著的增强,土壤养分贮量和速效养分供应强度得到明显的改善,土壤肥力得到不同程度的恢复。表明紫色土的治理应根据其所处的不同退化阶段而采取相应的治理措施,才能使土壤的物理化学性质、土壤肥力得到较好的恢复。郑本暖doaj +2 more sources晋西黄土区退耕还林后土壤入渗特征及土壤质量评价
