Subject:
biochar; carbon dioxide; feedstocks; soil; soil organic matter
Abstract:
... Methodologies based on ¹³C‐enrichment (E), ¹³C‐depletion (D) and ¹³C‐natural abundance (NA) to estimate the stability of biochar in soil were critically examined. The stability of ¹³C‐enriched biochar can be estimated by the quantitative recovery of excess ¹³C, either in the soil or in evolved CO₂. Both approaches have advantages and disadvantages. Recovery in the soil is a measure of both residua ...

These cause the spatial distribution of iron (Fe) and manganese (Mn) between the soil matrix and ferromanganese concretions or nodules. Since oxides of these metals may interact with organic matter, we studied their spatial distribution in bulk material from the Bg hor ...

Abstract:
... A model of phosphate reaction is constructed and its output compared with observations for the sorption and desorption of phosphate by soil. The model has three components: first, the reaction between divalent phosphate ions and a variable‐charge surface; second, the assumption that there is a range of values of surface properties and that these are normally distributed; third, the assumption that ...

Abstract:
... Archaeological Dark Earth soil is a category of archaeological anthrosols that has gained much attention because it exhibits higher nutrient content and organic matter stocks and a characteristic dark colour, and enables higher crop yields in comparison to neighbouring soil. However, much is unknown about the chemical properties of Archaeological Dark Earth soils in Central Europe. Therefore, we s ...

Abstract:
... Although plant canopies are widely recognized to protect the soil and help mitigate soil erosion, recent research has shown that the majority of soil scour prevention can be attributed to the roots. Because roots are more difficult and time‐consuming to measure than shoots, research in this area has largely been limited to understanding the influence of large roots and/or whole root systems, and t ...

Abstract:

To date, there has been little study of the share of the global soil carbon budget made up of carbon in Technosols or the contribution of Technosols to climate mitigation. A meta‐analysis is proposed based on the analysis of 130 articles and consisting of the extraction of 953 observations on soil or ...

Abstract:
... The oxygen isotope composition of phosphate (δ¹⁸O‐PO₄) has successfully been used to study the biological cycling of phosphorus (P) in seawater and marine sediments. However, only a few studies have used this approach in soils. In order to analyse δ¹⁸O‐PO₄, phosphate must be extracted from the soil, purified and converted to silver phosphate (Ag₃PO₄). The published extraction methods, successfully ...

Although methods exist for the purification of inorganic soil P pools, there is no pub ...

Abstract:
... Most agronomic crop models use a reservoir tipping‐bucket approach to model the water budget in the soil. Soil available water capacity (AWC) is the main soil property considered in this approach. Because AWC is difficult to measure, uncertainty in AWC may be high. We developed a method using a specific kriging technique to determine the effects of uncertainty in AWC on crop model predictions. The ...

Because of the difficulties in measuring soil vapour diffusion directly, modelling approaches have been used to estimate the vapour enhancement factor (η) by matching theory to measurements. In the method proposed by Hiraiwa ...

The total soil-water content is divided into free water and water in the diffuse double layer (DDL) around clay particles. These two fractions of soil water conduct electrical current through the soil and are assumed to act in parallel with the soil solid. The volume of water in the DDL is evaluated from the surface ar ...
