Characterization of soft soil using multi-channel analysis of surface waves (MASW) and electrical resistivity method (ERM) [PDF]

open access: yes, 2017
This thesis demonstrates the research on the soft soil characteristics using geophysical methods. The need on non-intrusive, time efficient, economic and larger volume of investigation had increased the demand of using geophysical methods for ...

Sediment and particulate carbon removal by pipe erosion increase over time in blanket peatlands as a consequence of land drainage [PDF]

open access: yes, 2006
Land drainage is common in peatlands. Artificially drained blanket peat catchments have been shown to have a significantly greater soil pipe density than intact catchments.

Carbon balance of rewetted and drained peat soils used for biomass production: a mesocosm study

open access: yes, 2016
Rewetting of drained peatlands has been recommended to reduce CO2 emissions and to restore the carbon sink function of peatlands. Recently, the combination of rewetting and biomass production (paludiculture) has gained interest as a possible land use ...

Evaluating sulfurization as a blue carbon sink in a southern California salt marsh

open access: yesLimnology and Oceanography, EarlyView.
Abstract Blue carbon ecosystems such as seagrass meadows, mangrove forests, and salt marshes are important carbon sinks that can store carbon for millennia. Recently, organic matter sulfurization and pyritization have been proposed as mechanisms of net carbon storage in blue carbon ecosystems. At our study site, organic sulfur that is resistant to acid

The ash content of the plough layer of peat lands cultivated by different methods

open access: yesAgricultural and Food Science, 1961
The results of this investigation justify the conclusion that the ash content of peat increases under cultivation through the effects of the administered fertilizers and soil improving agents.

Multi‐scale electrical resistivity imaging and long‐term monitoring as a tool for groundwater management

open access: yesNear Surface Geophysics, EarlyView.
Abstract Extensive pumping, storm floods or sea‐level rise can lead to regional and local‐scale processes of saltwater intrusion into coastal aquifers. Particularly when exacerbated by the impacts of climate change, these processes can threaten freshwater resources and thus drinking water supplies and need to be prevented by investigation and ...

Results from a soil improvement and fertilizing test on fen land at Leteensuo

open access: yesAgricultural and Food Science, 1961
Clay and sand, used as soil improving agents, have increased the hay crops as well as the cereal crops. When the fertilization contained phosphates only, the increases in crop yield produced by the soil improvement were quite high.

ESTIMATION OF SOIL-PROTECTIVE SYSTEM WITH USE OF BIORESOURCES OF AGRICULTURE ON THE BASIS OF USE OF AGROCENOSIS ON THE GREY FOREST SOILS [PDF]

open access: yesScientific Papers Series : Management, Economic Engineering in Agriculture and Rural Development, 2013
The experimental data of long-term researches establishing high efficiency of soil-protective system of agriculture with use of bioresources on biological and humus in condition of arable grey forest soil has been presented.

Changes in PM2.5 Peat Combustion Source Profiles with Atmospheric Aging in an Oxidation Flow Reactor

open access: yes, 2019
Smoke from laboratory chamber burning of peat fuels from Russia, Siberia, the USA (Alaska and Florida), and Malaysia representing boreal, temperate, subtropical, and tropical regions was sampled before and after passing through a potential-aerosol-mass ...

The missing woodland story: Implications of 1700 years of stand‐scale change on ‘naturalness’ and managing remnant broadleaved woodlands

open access: yesPeople and Nature, EarlyView.
Abstract Longer‐term perspectives—equivalent to the lifespans of long‐lived trees—are required to fully inform perceptions of ‘naturalness’ used in woodland conservation and management. Stand‐scale dynamics of an old growth temperate woodland are reconstructed using palaeoecological data.
