The uptake of selenium by perennial ryegrass in soils of different organic matter contents receiving sheep excreta [0.03%]
不同有机质含量土壤中施加羊粪后多年生黑麦草对硒的吸收研究
Pei-Tzu Kao,Heather L Buss,Steve P McGrath et al.
Pei-Tzu Kao et al.
Background and aims: The intake of selenium, an essential element for animals and humans, in ruminants is largely determined by selenium concentration in ingested forages, which take up selenium mainly from soil. Ruminant...

Plant-soil feedbacks have been recognised as playing a key role in a range of ecological processes, including succession, invasion, species coexistence and population dynamics. However, there is substantial variation between species in the ...
Continuous monitoring of chlorophyll a fluorescence and microclimatic conditions reveals warming-induced physiological damage in biocrust-forming lichens [0.03%]
叶绿素a荧光和微气候的连续监测揭示了地衣生物被膜暖化导致的生理损害
José Raggio,David S Pescador,Beatriz Gozalo et al.
José Raggio et al.
Purpose: Biocrust communities, which are important regulators of multiple ecosystem functions in drylands, are highly sensitive to climate change. There is growing evidence of the negative impacts of warming on the perfor...
Mechanisms of nitrogen transfer in a model clover-ryegrass pasture: a 15N-tracer approach [0.03%]
模型三叶草雀麦牧场氮传递的机制:一项基于15N示踪的方法
Michaela K Reay,Katrina A Pears,Alison Kuhl et al.
Michaela K Reay et al.
Purpose: Nitrogen (N) transfer from white clover (Trifolium repens cv.) to ryegrass (Lolium perenne cv.) has the potential to meet ryegrass N requirements. This study aimed to quantify N transfer in a mixed pasture and in...
Improving the remote estimation of soil organic carbon in complex ecosystems with Sentinel-2 and GIS using Gaussian processes regression [0.03%]
利用Sentinel-2和GIS高斯过程回归提高复杂生态系统中土壤有机碳的远程估算精度
Johanna Elizabeth Ayala Izurieta,Carlos Arturo Jara Santillán,Carmen Omaira Márquez et al.
Johanna Elizabeth Ayala Izurieta et al.
Background and aims: The quantitative retrieval of soil organic carbon (SOC) storage, particularly for soils with a large potential for carbon sequestration, is of global interest due to its link with the carbon cycle and...
Metalliferous habitats and seed microbes affect the seed morphology and reproductive strategy of Arabidopsis halleri [0.03%]
金属聚积环境和种子微生物影响阿拉波塞笳芥的种子形态和繁殖策略
Kamila Murawska-Wlodarczyk,Urszula Korzeniak,Andrzej Chlebicki et al.
Kamila Murawska-Wlodarczyk et al.
Purpose: Plant reproduction in metalliferous habitats is challenged by elevated concentrations of metal trace elements in soil. As part of their survival strategy, metal-tolerant plants have adjusted reproductive traits, ...
Harnessing belowground processes for sustainable intensification of agricultural systems [0.03%]

Yann Boursiac et al.
Background: Root water transport, which critically contributes to the plant water status and thereby plant productivity, has been the object of extensive experimental and theoretical studies. However, root systems represe...
A quick and simple spectrophotometric method to determine total carbon concentrations in root exudate samples of grass species [0.03%]
一种测定草类根系分泌物中总碳浓度的分光光度法
Eva Oburger,Christiana Staudinger,Andreea Spiridon et al.
Eva Oburger et al.
Purpose: Root exudates are key components driving belowground interaction between plant, microbes and soil. High-end analytical approaches provide advanced insights into exudate metabolite diversity, however, the amount o...
Nitrogen and phosphorus cycling in an ombrotrophic peatland: a benchmark for assessing change [0.03%]
氮和磷在高位沼泽中的循环:评估变化的参照标准
Verity G Salmon,Deanne J Brice,Scott Bridgham et al.
Verity G Salmon et al.
Aims: Slow decomposition and isolation from groundwater mean that ombrotrophic peatlands store a large amount of soil carbon (C) but have low availability of nitrogen (N) and phosphorus (P). To better understand the role ...
