Droplet infiltration dynamics and soil wettability related to soil organic matter of soil aggregate coatings and interiors

Carbon dynamics of soil organic matter in bulk soil and aggregate fraction during secondary succession in a Mediterranean environment

Soil Aggregate, Organic Matter and Microbial Dynamics under Different Amendments after 27 Years of Mine Soil Development

Physical and biological properties of soils developing from spoil material following surface coal mining in southwest Virginia are poorly understood. Additionally, the effects of various types of soil amendments such as sawdust, topsoil or biosolids on long-term soil development are lacking in the current literature. The objective of this study was to examine water stable aggregation, organic m...

Aggregate and soil organic carbon dynamics in South Chilean Andisols

Extreme sensitivity of soil organic carbon (SOC) to climate and land use change warrants further research in different terrestrial ecosystems. The aim of this study was to investigate the link between aggregate and SOC dynamics in a chronosequence of three different land uses of a south Chilean Andisol: a second growth Nothofagus obliqua forest (SGFOR), a grassland (GRASS) and a Pinus radiata p...

Soil Organic Matter: Its Fractionation and Role in Soil Structure

An understanding of the form and function of SOM in soil is essential to sustainable crop production. Various methods of SOM fractionation are used to study SOM forms and to gain an understanding of interaction between SOM and aggregate formation. Physical SOM fractionation techniques are based on the concept that SOM associated with particles of various sizes. differs in structure and function...

Sustainable Agriculture, Soil Health, and Soil Organic Matter

The latter two principles protect the soil resource on which all food and fibre production ultimately depends. However, agricultural production systems differ from ‘natural’ or undeveloped systems in that they can be considered to be ‘leaky’ with respect to nutrients. This is inevitable, due to nutrient removal in harvested product, but inappropriate fertiliser management can exacerbate the ‘le...
