Long-term nitrogen deposition linked to reduced water use efficiency in forests with low phosphorus availability [PDF]

, 2016
1. The impact of long-term nitrogen (N) deposition is under-studied in phosphorus (P)-limited subtropical forests. We exploited historically collected herbarium specimens to investigate potential physiological responses of trees in three subtropical ...

Microbial Nutrient Limitation of Different Tea Cultivars: Evidence from Five Representative Cultivars

Agronomy
Soil microbial activity is generally limited by the availability of carbon (C), nitrogen (N), or phosphorus (P) in agricultural ecosystems. Soil ecoenzymatic activity (EEA), ecoenzymatic stoichiometry (EES), and vector characteristics were examined to ...

Litter chemical quality strongly affects forest floor microbial groups and ecoenzymatic stoichiometry in the subalpine forest [PDF]

Annals of Forest Science, 2019
AbstractKey messageLitter chemical quality regulates the distinct composition of the main microbial groups and ecoenzymatic stoichiometry. Microbes in spruce (Picea asperataMast.) and fir (Abies faxonianaRehd.) rather than birch (Betula platyphyllaSuk.) and rhododendron (Rhododendron lapponicum(L.) Wahl.) can more easily adjust their physiological ...

Natural fallow alleviates carbon and nitrogen limitation of microorganisms and plants in paddy fields

Functional Ecology, Volume 39, Issue 8, Page 1972-1981, August 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Carbon (C), nitrogen (N) and phosphorus (P) serve as critical limiting factors for plant–microbe colonization and growth in agroecosystems, while simultaneously functioning as key regulatory controls for soil C emissions.

Bedrock geochemistry regulates glomalin-related soil protein accrual in subtropical karst forest soils, Southwest China

Ecological Indicators
Lithology-driven changes in forest soil nutrients have a strong impact on glomalin-related soil protein (GRSP). GRSP is a key component of the stable microbial-derived carbon (C) pools in soil and plays an important role in promoting the accumulation and

Balancing macronutrient stoichiometry to alleviate eutrophication [PDF]

, 2018
Reactive nitrogen (N) and phosphorus (P) inputs to surface waters modify aquatic environments and affect public health and recreation. Until now, source control is the dominating measure of eutrophication management, and biological regulation of ...

Initial Soil Organic Carbon Level Governs Contrasting Carbon Responses to Fresh-Straw Input in Long-Term Straw-Returned Soils

Agronomy
Soil organic carbon (SOC) responses to straw return are strongly influenced by active carbon dynamics and extracellular enzyme responses, yet how these processes vary with initial SOC status and long-term straw-return history remains unclear.

Effects of Mixing Feldspathic Sandstone and Sand on Soil Microbial Biomass and Extracellular Enzyme Activities—A Case Study in Mu Us Sandy Land in China

Applied Sciences, 2019
Microbial biomass, extracellular enzyme activity, and their stoichiometry in soil play an important role in ecosystem dynamics and functioning. To better understand the improvement of sand soil quality and the limitation of soil nutrients after adding ...

Carbon transit through degradation networks [PDF]

, 2013
The decay of organic matter in natural ecosystems is controlled by a network of biologically, physically, and chemically driven processes. Decomposing organic matter is often described as a continuum that transforms and degrades over a wide range of ...
