Long-term effects of nitrogen fertilization on methane emissions in drained tropical peatland

open access: yesScientific Reports
Nitrogen (N) fertilization improves crop productivity. However, the long-term effects of N application on methane (CH4) emissions in drained peat soils, particularly under different hydrological conditions, remain poorly understood.

Wood‐Based Bioelectronics: Lignosulfonate‐Based Conductive Biocomposites for Paper Organic Electrochemical Transistors

open access: yesAdvanced Electronic Materials, EarlyView.
Biodegradable wood‐based bioelectronics are realized by integrating poly (2,3‐ethylenedioxythiopene:lignosulfonate (PEDOT:LigS) as a mixed ionicelectronic channel in organic electrochemical transistors fabricated on paper substrates. The biocomposite exhibits high conductivity, biocompatibility, and strong transistor performance, while devices built on

Uncovering renewable energy policy impact channels on land values, the local farm structure, and farmland heterogeneity

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...

Runoff production in blanket peat covered catchments [PDF]

open access: yes, 2000
Although blanket peat covers many major headwater areas in Britain, runoff production within these upland catchments is poorly understood. This thesis examines runoff production mechanisms within the blanket peat catchments of the Moor House National ...

Effect of soil properties on soil respiration in cultivated soils with varying organic matter content [PDF]

open access: yes, 2023
The relationship between carbon dioxide (CO2) production in soil respiration and soil carbon (C) content was studied using soil samples from agricultural field parcels where the C content changed along a transect within the field.

Optimizing Strategies for Non‐Invasive Prospection of Settlements in the Intertidal Zone: A Case Study From the Centre of the Drowned Medieval Village of Tolsende (Scheldt Estuary, the Netherlands)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Medieval and early modern drowned villages in the intertidal zone of the Scheldt estuary (the Netherlands) constitute intriguing yet largely understudied components of north‐western Europe's underwater cultural heritage. Despite their high archaeological potential as time capsules of past settlement landscapes, research has remained limited ...

Assessment of variability of peat physicochemical properties, subsidence and their interactions within Selangor forests [PDF]

open access: yes, 2023
Tropical peat swamp forests are carbon rich ecosystems both above- and below-ground, which play a major role in the climate balance of the earth. The majority of the world’s tropical peat forest cover is located in Southeast Asia and is increasingly ...
