- Abstract:
- ... In this article, we present a graphical user interface software for the litter decomposition and soil carbon model Yasso07 and an overview of the principles and formulae it is based on. The software can be used to test the model and use it in simple applications. Yasso07 is applicable to upland soils of different ecosystems worldwide, because it has been developed using data covering the global cl ...

- Abstract:
- ... On-going, high-profile public debate about climate change has focussed attention on how to monitor the soil organic carbon stock (Cₛ) of rangelands (savannas). Unfortunately, optimal sampling of the rangelands for baseline Cₛ – the critical first step towards efficient monitoring – has received relatively little attention to date. Moreover, in the rangelands of tropical Australia relatively little ...

The objective of this study was to determine the effect of soil compaction on soil microbiological properties related to N in a claypan soil amended with poultry litter (i.e., Turkey (Meleagris gallopavo) excrement mixed with pine shavings as b ...

- Abstract:
- ... Land-use change from perennial grasslands to cultivated croplands leads to reduced soil organic C (SOC) and total N. Among other factors, introduction of annual crops and soil disturbance by tillage may account for reduced amounts of SOC and total N. However, agricultural practices of no-till and N fertilizer application may maintain soil N in cropped soils. We measured soil N changes and N-use ef ...

There are increasing concerns that climatic and land use changes will enhance soil respiration rates and soil organic carbon loss, compromising agricultural productivity and further elevating atmospheric CO₂. Current understanding of dryland respiration is, however, insufficient to enable prediction of the consequences of these changes for dryland soils and CO₂ fluxes. The objectives of this paper ...

Previous studies in non-saline soils have shown that rewetting induces a flush of soil respiration, but little is known about how the extent of drying affects the size of the respiration flush or how drying and rewetting affects soil respir ...

Simulation models are important tools in the long-term assessment of soil organic carbon (SOC) stock changes caused by agriculture, but proper parameter adjustments for the underlying environmental context are essential for an accurate assessment of the models ability to predict SOC.

In order to reduce uncertainties from upscaling spatial processes of the DeNitrification–DeComposition (DNDC) model for improving the understanding of C sequestration under recommended management practices (RMPs), we parameterized the DNDC model with a 1:1,000,000 polygonal soil ...

A successful determination of spectrally active soil components with visible and near infrared reflectance spectroscopy (VIS-NIRS, 400–2500nm) depends on the selection of an adequate multivariate calibration technique. In this study, the contents of thermolabile organic carbon (C₃₇₅°C), the inert organic C fraction (Cᵢₙₑᵣₜ) and the sum of both (total soil organic carbon, OCₜₒₜ) were estimated with ...

N fertilization can also affect the soil organic carbon (SOC) pool. Therefore, this study was conducted to assess the effects of N fertilization on switchgrass biomass production and the SOC stock in Ohio. ...

This presents Ireland with the opportunity to offset carbon emissions through carbon sequestration in forests, as the latter are known to sequester a large amount of carbon into the tree biomass. However, the effects of afforestation on soil organic carbon in the Irish humid ...
